We have visited this campground twice over the years, the most recent as part of roadtrip back from Yosemite.  The quality of the experience really has to do with what loop you camp in.  If you look at the website for the park there is a notice that they are getting ready to do construction and it appears many of the issues will be fixed.

Right now, I'd strongly recommend camping in the upper part of the "A", "B" or "C" loops.  The lower parts of "A" and "B" are pretty exposed with just dune grass/bushes for protection.  The bathrooms in those loops are also in the best shape.  The "D" loop needs a lot of work.  The bathroom is very mildewed and just bearable.

I don't have a lot to add beyond what has been said by others.  This campground is about the location.  It is nestled right in the state park w/old growth redwood trees and hikes accessible directly from the campground.

However, it is very tight, which is difficult for anyone with a larger trailer.  The facilities are showing their ages as well.  The showers were in decent shape, but the bathrooms could use some work. 

It is still the best campground for exploring the park though.  And the negatives should not turn you away.

We used Diamond Gulch as our base while exploring Yosemite for 5 days.  Overall, it was a great experience with a great host!  We visited in mid to late July, so it was very hot, and this means the campground was a little dusty, but manageable.  As others have stated, there is free firewood at your site, but we were a little scared to light a wood fire given how everything was so dry.  Also, as others have mentioned the showers were great, but we did have issues with getting them to heat up.  

One thing to keep in mind is that while Groveland is only ~30 minutes from Yosemite, the drive within the park can take up 45-60 minutes.  So, plan accordingly and be prepared.  Our experience was that if we left camp around 7:30 we'd be through the gate with no line at 8am, and be at a parking lot around 9am.  This always worked for us to get a parking spot without any hassle.  After a long day of hiking and exploring the drive back to the campground felt a little long.

Something we did not expect was how little there is in Groveland itself.  We tried to spend a couple of hours there one afternoon, and ended up just grabbing coffee and going back to camp.  There just isn't much to do in town.  This isn't to discourage anyone, but keep that in mind.

The good:

* Good host

* Beautiful scenery from camp

* Clean, well serviced bathrooms (porta potties)

* Water available in camp

* Excellent showers (especially when you can get them to heat up)

* Very relaxed atmosphere

The okay:

* The sites have wood chips spread to keep down dust, but those get tracked everywhere.

* A bit of a drive from the sights in Yosemite

* On busy weekends it can get a bit crowded

Like others that have reviewed this campground I agree this is great for an in-city campground. Yes, you can hear the freeway it it becomes white noise at night. There are a lot of permanent residents but it’s a nice, clean facility. If you have something to do in the Tri-cities and want to camp, this is a great choice.

I’d recommend any of the sites in the newer section.

I can see how this resort could charge these prices at one time, but not now. The current resort is a little run down. The grass is weedy and has bare spots. The bathrooms are clean but have seen a lot of use. The showers, especially the men’s, have seen better days. I’m not saying the resort is horrible, but it is hard to reconcile how much you pay with the current state.

A good example is he storage they provide at each site and want you to use. Every one of them I looked at had broken, hanging doors. Again, not a huge deal, but at this price it’s not what you would expect.

Pros:

• quiet for a city park
• level spots
• large spaces
• a great launching point for adventures in Bend

Okay:

• bathrooms can be a hike for those without in their trailer

Cons:

• expensive
• tables at the site are teeny with only two chairs
• a lot of rules

We stayed here for almost a week while exploring Canyon Lands and Arches NP. It was a last second change of plans after our original destination had a blizzard! This campground is right on the southern edge of Moab, so not an out-in-nature experience.

Good:

• Very clean and well maintained park
• Easy to walk into town for shopping and food
• Short drive to both Canyonlands and Arches
• Good access to bicycle trails
• Laundry, convenience store, gas station and propane all on site

Okay:

• It’s a bit close quarters
• A bit of road noise
• No grass at sites, it’s all gravel

Bad:

• There is a car wash near the park that tells people to “pull forward” regardless of time of night

We did visit this park during “Jeep Week” which did have some impacts. People were cleaning their jeeps at all hours (see note about the car wash). It also meant that it was pretty loud with people showing off. I didn’t hold that against the campground, but be aware if you visit and want to avoid.

There are already som nice reviews of this campground and they are spot on. It’s easy access, clean, and even after hours was easy to check-in.

I will add that they are very communicative about your upcoming visit. I received several messages from them ahead of my visit to provide additional info and welcome.

It’s close enough to run into Caldwell for dinner and there are some really good restaurants and coffee shops I town.

They even had Easter activities for families the morning we were leaving.

We stopped here during a road trip and it was a good choice. This is a pretty standard KOA experience.

Good:

• Easy on and off the highway. Including a convenient gas station when leaving in the morning.
• Easy access to restaurants in Twin Falls
• Clean campground
• Very nice and clean bathrooms
• Great staff who moved us to a better site even though we were just overnighting
• Near the falls if you want to visit

Okay:

• As expected, the sites are a bit tight. At least in the RV section.
• A bit of road noise from the highway and the road it’s on
• Some cow pastures in the area, so there was occasional aroma
• Pretty windy the night we visited

I had wanted to visit this campground for years and it was worth it. The feel of this campground is very different than those just down the road towards Cle Elum. Much closer to an alpine feel than the lower pine forests. It’s a very peaceful campground with a lot of large private sites and also sites along the river. In fact the river runs down two sides of the campground.

It is a more primitive campground. There are only pit toilets and water that must be hand pumped. There is also a picnic area for day use.

We arrived here Wednesday evening and found a site pretty easily (we had no reservation). There were sites available until Friday mid-day.

Activities include hiking, biking, playing in the river and visits to Roslyn.

The good:

• well maintained
• paved roads and driveways
• a lot of sites on the river and access for those not
• large private sites
• double sites
• a lot of nearby activities

The bad:

• nothing comes to mind

The OK:

• decent smelling pit toilets
• limited potable water (all hand pumps and only 1 or 2 were working during our visit)

We have camped here three times over the last 7 years.  Sometimes for full vacations, sometimes just as part of a larger trip, and I always love it.  The lake is beautiful, with great views of Mt. Hood.  The little store has snacks and some food as treats and rents kayaks, row boats, etc.  The showers are very nice and clean.  The campsites are huge and very private.  There are even a few trails which leave from the campground if you want to hike.  And for those that want less rustic they even have yurts!

Now, it is busy, especially on the weekends.  There is a reason for that.  If you want to spend the day at one of the spots on the lake, you have to get up early and get your spot (by 9am, even on a weekday).  On the weekend it can be a bit of a mad house with people coming from outside the campground, so I recommend staying during the week.

Also, the bathrooms are pit toilets.  They aren't bad, but still pits. :)

Pros:

* Beautiful lake

* Close to Hood River

* Hiking from the campground

* Store with treats

* Very nice showers

* Very nice campsites with lots of space

Cons:

* Very crowded on the weekends

OK:

* Pit toilets

A lot of people really love this campground and I had high hopes, but I was disappointed.  This campground is right on East Lake at Newberry National Volcanic Monument.  It's fairly long and narrow with quite a few sites, some right on the water.  No sites have utilities and the bathrooms were old, fairly dirty pit toilets (except one which had two flush toilets).  

The first issue I had with this campground was that the sites are fairly closely packed.  You can see in the photos below that there was little privacy.  The second issue I had was the bathrooms were old, rundown and quite smelly.  The worse issue though was the bugs.  They were horrible.  I'm willing to concede they probably are not all year, but our 4 days were not good.

Pros:

* Lake access with fishing, kayaking, etc…

* Close to the East Lake Resort if you want a bite to eat out

* Hiking trails leave right from the campground

Cons:

* Bathrooms

* Insects (at least seasonally)

* Little to no privacy

OK:

* The lake was not pristine, it looks like its been invaded by non native grasses and algae

Mazama campground is a great place to camp while visiting Crater Lake NP.  I was pleasantly surprised given some reviews I've seen.  The campground has quite a few sites, but they are generally spread out enough to give you privacy.  The bathrooms are fairly new and maintained.  The showers were still closed for Covid when we visited, so I have no idea how they looked.  There are even some sites with power, which I've seen very rarely in NPs.  On top of it all, you're very close to a store, restaurant, gas and Crater Lake! 

Pros:

* Well maintained

* Cafe/restaurant close to the campground

* Pretty loop hike right at the campground

* Crater Lake is close

* Ranger programs

Cons:

* Pumice volcanic soil gets everywhere

OK:

* The bathrooms smelled a bit mildewed

This campground is just south of Lassen Volcanic National Park.  It has two main sections, one for RVs and the other for tents.  There are a small number of RV sites with full hookups and then a larger number of tent sites.  The RV sites are fairly small, but felt separated enough to have some privacy.  The tent sites are a bit more rustic.

The other slightly odd part is that most of the RV sites were filled with people who came and stayed for the entire summer, year after year.  We were the only not long-term camper in the RV section.  

Pros:

* Close to a lot of amazing scenery with Lassen

* Well kept, clean, quiet campground

* Camp store/restaurant is great

* Laundry on site

* Access to a nice little creek w/swimming hole

Cons:

* Camp store is open limited days

* Tent sites only have pit toilets which are not the best maintained

OK:

* No fires in the RV sites

* Showers were not always very clean

All the earlier reviews on this campground are correct. It’s cramped, with very little privacy. We laughed that it looked like we were parked at the grocery store instead of camping. The campsites on the end (21), by the lake (22-30), or by the creek (7-9) are probably the best, but still not great.

However, if you view this as a place to sleep while you explore a beautiful lake with great hiking, it becomes more palatable.

The good:

• The lake is fantastic.
• The hiking is great
• the devil’s punch bowl
• Spruce railroad trail for cycling

The okay:

• Park common areas

The bad:

• Cramped camping
• Bathrooms are very dated

The Ohanapecosh campground is on the southeast side of Mount Rainier NP in old growth forest.  There are a streams and a river running through the campground, so a lot of sites are on water.  Its fairly standard for a NP campground, with a fair amount of privacy for each camp, but also with facilities which are getting older.

While the campground is a long way from the "main" areas of the park, I really like camping here.  You are away from a lot of the crowds that you find at the other two campgrounds within the park, and Ohanapecosh takes reservations.  You can also do some pretty nice hikes right from your site, including Silver Falls, which are very nice.

Pros:

* Quiet (well, quiet with stream/river background noise)

* Large sites w/privacy

* Hiking from the park

Cons:

* Facilities are showing their age

* Sites are rustic, often not very level, and sometimes difficult to get into

* You have to drive ~1 hour to Longmire or Paradise

NOTE: you cannot bring larger trailers into this campground.  The roads are very tight!

We stopped here on our way home from a recent trip and was a good stop over point. I’m not sure what activities are possible as a destination campground but maybe water sports?

The good:

• Easy on and off from the highway
• Clean bathrooms
• Easy, pull through sites
• Very friendly staff
• They have a grill which will deliver breakfast, lunch or dinner to your site

The mixed:

• It is an RV resort laid out like a grassy parking lot
• A lot of resident campers

The bad:

• The highway was very loud from our site
• No picnic table or fire pit

We spent four days here for spring break this year while exploring Zion NP. It’s basically just reserved, dispersed camping with outhouses. That said, you are much more spread out than the free dispersed camping around the park.

The good:

• The views were amazing right at our campsite.
• There was a fair amount of privacy with everyone spread out through the field.
• Proximity to Zion (40 minutes to the park entrance or just up the road for some hiking)

The mixed:

• There are outhouses but they can get fairly full before they get cleaned. They were full when we arrived but cleaned a couple days later.
• The wind. You are on a plateau with little cover. The winds were coming from the south when we were there so you can try and find a spot with some protection.
• The road is rough, both up to the campground and within it. Take it slow and you will be fine but it can be a bit intimidating. I would be concerned trying it when wet.

We stayed here overnight on our trip and were very happy with the campground. Everything is very clean and well maintained. Most of the campground looks new or at least newly renovated. Bathrooms and showers were very clean. There is also a game room with foos ball and air hockey.

It’s an easy off and on from the freeway which is nice, but that does mean you hear the freeway from camp.

The host was particular about where we park but it was to avoid the sprinklers in the lawn. And there are rules about what can be on the lawn. It was nothing surprising or crazy though.

While we do not atv it looks like this would be a great place to stay if you did. They have a lot of information on local trails complete with suggestions.

As others have said, this campground is on the reservoir at Moses Lake, but it is maybe 20-30 minutes from town. There are really several sections to this campground and they each have a different feel. I am not much of a fisherman, and have always stopped here while traveling, but I have always found it relaxing. If you are a fisherman, you will probably love this campground. Otherwise it would be a nice place to spend a weekend relaxing with friends.

The RV sites are separated into groups of circles where the sites radiate off like spokes on a wheel. Tall poplars surround these groups to break up the wind that can really get blowing in this area of the state. The sites themselves are gravel driveways in a grass field. There are trees within each group but there is very little privacy, even though the sites are quite large. These sites have access to a single restroom with flush toilets and showers. However, the restroom is starting to show its age quite badly.

The tent sites are in two loops amongst some trees. These are definitely my favorites spots in the campground. The sites are gravel/dirt driveways in a more rustic and less grassy setting. These sites are not level, so any RV will require some effort if you care about that. Privacy is still not great but it is better than the RV sites. The biggest issue with the tent sites is that the restrooms are pit toilets (I believe, but I didn’t go in).

Look, it is a KOA. Some people like them, some do not. We generally avoid them and prefer more rustic camping. However, we decided to stay here to avoid some of the bear restrictions within Glacier, and for something different.

This park is very nice, but I would never call it rustic. We stayed in an electric and water only site which was tucked in some trees. Other sites were very landscaped, like a backyard. In fact, those have patios with awnings and BBQs provided. Our site was a bit small, with our neighbors close to our outdoor area. There were several tent only sites which looked fantastic and were back within the trees.

The staff is very friendly and everything was very clean. It was nice having a small outdoor restaurant, but it’s selection was very limited (4 meat choices, 2 sides with your meat). The ice cream shop was probably the biggest hit. There are also two pools, one adult and one family, and also two adult only hot tubs. When we stayed there it was in the mid-90s, so the pools were a life saver.
