High in the Caribou–Targhee National Forest, 90 miles northeast of Idaho Falls, Henrys Lake is a stone’s throw from the Continental Divide and the western boundary of Yellowstone National Park. Situated in a wide, flat basin, and surrounded by 10,000-foot peaks, this shallow alpine lake is as popular with migrating birds as it is with local sport fishers. The small state park at Henrys Lake is a great spot for spending a few days fishing, lounging and wildlife watching, or for exploring some of the area’s other attractions, including Yellowstone, Harriman State Park, Mesa Falls, and various hiking, horseback, and ATV trails. 

Campers visiting Henrys Lake State Park will find more than 80 tent and RV sites situated near the lake’s eastern shore. Sites are equipped with electrical and water hookups, picnic tables, and fire pits with cooking grills. Some sites are ADA accessible. Campground amenities include flush restrooms, showers, picnic areas. A dump station is located onsite. The park also has a few camping cabins for rent. Dogs are permitted in the park, but must remain leashed. Camping is available from mid-May through mid-October. Sites are $20–$31/night; cabins are $50–$55/night; reservations are accepted.

For fishing on the lake, the park has a boat ramp and fish cleaning station. Yellowstone cutthroat is the most common at Henrys Lake, but there is also a significant number of cutthroat-rainbow (cut-bow) hybrids. Paddlers can launch from the beach area; kayak rentals are available. Wildlife watching from the park’s 3 miles of hiking and biking trails—as well as the lake’s shoreline–can be exceptional. Besides the prolific number of migrating birds, including waterfowl, eagles and hawks, there are frequent sightings of deer, moose, and antelope. The park also hosts seasonal nature programs.

Henrys Lake State Park Campground

Nice campground right on a lake and close to the west entrance to Yellowstone Smallish state park (44 sites plus several cabins) right on Henry’s Lake. Located 16 miles from West Yellowstone, MT (and the west entrance to Yellowstone NP), it is a nice quiet place to camp but with easy access to the park. We camped here for three nights and our site (35) had a view of the water but in my opinion, Site 33 is the best as you have an unobstructed view of the lake. We reserved our site in March for July and are glad we did as the campground was full. Sites are either electric and water or electric with access to water. The bath/shower house in the Blue Dun Loop was new and immaculate (I dropped my soap in the shower and had no qualms about picking it up and using!) However, they are still working out the kinks and there was a sign warning that there may not be hot water; I had one hot shower and one cold one! I saw single kayaks near the dock which I assume were available for rentals although we did not inquire further. I highly recommend a day trip to Upper Mesa Falls (your camping tag will give you access with no additional fee) and/or Earthquake Lake. We did both in one day. Lots of families with kids and apart from the rude campers next to us who arrived at 1:00 am running their diesel engine for 45 minutes while they set up, it was very quiet after dark. I would give this campground 5 stars except for lack of privacy between sites and not a lot of shade and it was HOT in July.

Very nice campground on a lake

We stayed here for two days and it was just incredible. We experienced unbelievable midnight lightening storms and went on solitary wildflower walks populated by gorgeous trees and loads of deer and chipmunks (bring bug repellent).

Most of the campers are in giant luxury RV's and never seem to leave their rigs so the whole place is quiet and great for watching birds and stormy looking skies across the lake. I was on a two month trip and took some of the best pictures here.

If the Ranger named Richard is around he'll take you on a gorgeous wildflower hike and talk and tell you the secrets of the landscape.

You can't swim in the lake because of the leeches, but you could bring a boat or just park yourself by the side and quietly drink in the magnificence. 

Everyone who works there is special--there's young ranger Richard and an older fellow from Georgia who comes out every summer as a volunteer and brings good stories and plenty of advice if you need or want it for local attractions. 

This is not to be missed and very nearby big attention-getting Yellowstone so it's often overlooked. 

All the facilities were clean and working and the place was very very very well stocked with volunteers who clean, patrol and love the place up big time.

I will definitely go back there again.

A dramatic lake full of wildlife, weather, solitude and romantic views

Very nice campground right on the water. There are both camping spots for campers and tents, as well as a few cabins. The bathrooms are very nice and clean, with showers and flushing toilets. Site we reserved had water and electricity hook ups. Beautiful spot near both West Yellowstone and Island Park. Lots to do including: fishing, hiking, floating the river in Island Park, driving through Yellowstone, horseback riding, etc.

Henry's Lake

Upon our arrival at this campsite we were met with the most spectacular sunsets. The views of three mountain passes and the haze and cloud cover from a forest fire in the distance provided great views. It was windy at times so that limited the cooking we were able to do over an open fire like we typically would. One of the things that we did was purchase a new grill which the boys put together soon after our arrival. L did a bunch of the work and did a great job following the instructions. The campsite had an older section and a newer section. We didn't know this when we booked the site and was fortunate enough to get in the "new" section where the sites and driveway was paved and had new showers and restrooms. Had it not been for the windy conditions this might have been the perfect campsite. 

There was a boat launch at the campsite and the lake offers boat rentals from a neighboring marina. The rivers provided better fishing due to the high winds but the views didn't disappoint. On a positive note, the winds kept the bugs away. When the winds died down, the bugs made an appearance and were in plentiful supply.  

I am in favor of returning again, it was 15 miles from the West Yellowstone entrance in Montana. So you had easy access to grocery stores, gas stations, as well as one of the most beautiful National Parks in the country.  

The view above is of the restroom/shower area. If you look closely, you'll see L near the building. On the roof of the building was a Peregrine Falcon! That happens to be the first one he's seen in the wild up close. He's seen them flying but much further in the distance. He was so incredibly happy that he was able to observe this bird of prey up close.  

This place would have been close to perfect had it not been so buggy when the winds slowed

This was a nice park and the bathrooms were well maintained. The spaces seemed a little close together but wasn't too bad!

Very nice 

State run Site. Save money with the Idaho State Parks Pass.

RV and tent camping fishing and boating. I have stayed here numerous times. Cell service spotty but can be achieved. Wildlife can be viewed from inside RV. As stated before can get windy at times.

Very close to other places to visit; Yellowstone NP, Mesa Falls, Harriman State Park, Earthquake Lake, Big Spring, really to many to list.

Quiet gorgeous setting 

Beautiful setting in a mountain meadow covered in wildflowers, along a high mountain lake, surrounded by mountains! 
There is very little shade, but there is a steady breeze during the day that keeps things comfortable.
Mosquitos in the evening!
Water and electric sites, with a dump station.
A few pull thru sites.
Very nice and relaxing 
Just 15 miles from Yellowstone 

Mountain Views & wildflowers 

It’s a pretty huge campground. We didn’t even realize it until we wandered through for an evening walk and saw the entire other section of the campground. Most sites had fire pits, and they’re pretty well spaced out so you’re not on top of your neighbor. My kids loved riding their bikes around the campsites and there are some really cool trails. Paved if your of that speed, but it looked like there was a pretty rigorous hike up along a ridge. We used it as a basecamp for day trips into Yellowstone and it was reasonable. There were a lot of signs for fishing on The lake, but we were not really there for that.   

Beautiful and so much to do  

This campground was great for myself and my wife. About 45 minutes to an hour from Ole Faithful. An easy 3 hour drive to Grand Teton as well! Campground was clean, staff was nice, and we even had perfect weather in mid-June. A few mosquitos but nothing bad. Views were beautiful also. I'll say, this campground has the nicest restrooms and showers I have EVER seen for a campground. Clean, warm, and with great water pressure. Hope to be back!

Great spot outside of Yellowstone!

The campground has alot of spots available for tent and rv campers. They also have a few cabins as well. The cabins just have beds in them and no other amenities. The bathrooms were the cleanest ive ever seen for a campground to include their showers. The water is great for drinking and the lake is easy to access from 80% of the camping spots. They have pavilions for picnics and large areas for dogs and kids to play. The water on the south side of the lake by the dock is Shallow for quite a ways so swimming with kids is doable. The lake is forgiving for kayaks and other small watercraft until the wind picks up then it can be dangerous. The staff was awesome, they had bear bins for your trash and the park was well maintained. If your looking for a nice getaway give this park a shot, you won't be disappointed.

A + Campground

There is great boon docking outside of the organized campground area.  Follow your GPS to 44°35'52"N x 111°25'18"W.  At ~6,500 feet, the views of Lake Henry are amazing.  There are 15-20 spots suitable for RV's (of any length) plus campsites.  It's a great location, only about 20-30 minutes from West Yellowstone and the entrance to the national park.  We could have stayed here for days!  

  

5-bar coverage on Verizon.

Epic Views.  Great Location.

There is great boon docking by Lake Henry.  Follow your GPS to 44°36'52"N x 111°25'18"W.  With space for 15-20 campsites suitable for RV's (of any length) or tent camping, you'll be treated to epic views.  Ample fishing, natures walks, sitting on the (rocky) beach, or staging for Yellowstone (it's a short 20-30 min drive to West Yellowstone), the location and views are epic.  Good coverage, with 5-bars (boosted) on Verizon.  We'll be back!

Epic View.  Great Location.

What beautiful views and an awesome spot to stay.  We had fantastic fishing in the lake. The sites are maintained well and very neat. It was one of the nicest campground we've ever stayed.  The showers were spacious and very clean.   

A BIG issue for us was we were given no heads up that their sanitary station wasn’t working.  We made reservations back in January and nothing was on the website.  They really should have followed up with emails or even phone calls!   We weren't even told when we checked in either.  With an issue this bad, there should have been some communication and a discounted price since the dump wasn't available to use.   We had to back track 40 minutes into West Yellowstone and pay to dump at the Grizzly RV Campground before heading north to Glacier.

Should be 5 stars but the sanitary dump wasn't working without a heads up

Henry’s Lake is an absolutely beautiful place. The campground and facilities were generally clean. We loved the location in proximity to Yellowstone. Our site had water and electricity. 

We were in a pop up and the wind was a bit strong and unpredictable for us. One night we had to move down the road to the KOA to get out of the wind. If we were in our travel trailer we probably would have been okay. 

Depending on the direction of the wind and your site, you may get the aroma from the fish cleaning station and vault toilets by the boat ramp. We were out most of the time so it wasn’t an issue. If we stay here again, we would get a site away from the boat ramp. 

Several of our neighbors were disappointed with the dump station being closed and the lack of notification. We did see the alert on the site and didn’t need sewer hookup. This wasn’t an issue for us. 

Overall, this is a great campground. We would certainly stay again if in our TT. 

Beautiful but Windy

Great electric sites with shared water. There are only  8 sites with full hookups. The shower rooms are brand new and the best I’ve seen. Almost worth five stars except the dump station is closed and mosquitoes are torturous all day and night. 

Beautiful views

Nice enough State Park. Busy with RV's and families, but easy access to West Yellowstone and fishing on the river. Be prepared for wind.

Easy access to West Yellowstone and Henrys Fork

You're greeted by friendly Idaho State Parks volunteers at the kiosk and given a brief rundown about the park including easy to follow directions to your campsite.  

There are hiking trails with great views of the lake and wildlife.  Bring your camera and binoculars because the bird watching is phenomenal. 

The park is very clean and well maintained. Each RV site has electricity and shared access to water or individual water depending on the site.  Each RV site is paved and has a fire ring.  The sites are very nicely spaced. 

Caddis Loop sites have water and power and 8 sites have sewer, but half or more of the sites are not level. Adams and Blue Dun loops have power,  water, trees and most sites are level.

Restrooms and showers are cleaned daily and restocked throughout the day.

Impressively, 99.9% of campers do a good job picking up after themselves.  Trash is picked up daily at 930am at your campsite.  There are no dumpsters. 

The campground dump station is out of service for the 2021 season. There was a notice warning about that on the reservation website. The park has 8 sites with sewer connections that cannot be shared, so plan accordingly. 

The resident park ranger is very pleasant as are the resident volunteers that do the bulk of the park maintenance and cleaning.

Stunning views, close to Yellowstone NP

Everyone is very respectful of nature and preserving its beauty for all to enjoy and the park is well kept and clean.  Gorgeous scenery and wildlife.  

Beautiful and quiet

This campground is situation on Henrys Lake and provides amazing views from the campground. There are trails to explore without going too far. The park is ~20 minutes from the West Yellowstone entry, but nestled away from the hustle of the tourist town. Clean shower house.  Super friendly staff/hosts/rangers. 

My only negative is it’s $71 a night if you’re a non-Idaho resident. 

Overall we’d stay here again hands down! 

Amazing Views & Great Yellowstone Base

This place surprised us and is in an excellent location drivable to Yellowstone but far enough away from the hustle bustle. Sites are huge and really spaced out. We literally saw many bald eagles every day hunting in the lake. Beautiful campground and well maintained!

Bald eagles galore

Staff friendly, view lovely.

Definitely peeved that there is a $30 upcharge for non-residents and they only give discounts to Idaho military. Interesting!! North Carolina should consider doing this since we have BEAUTIFUL state parks too. Do what Idaho is doing to everyone else...kind of sad...would have given five stars if wasn't for this....army vet of 22 years.
