    Croton-on-Hudson, New York

    Croton Point Park is a 508-acre park situated on a peninsula on the east shore of the Hudson River. This park offers year-round events and activities and has facilities for camping, hiking and swimming. The park, rich in natural and human history, is also the site of historic wine cellars that are thought of be the oldest in New York State and the Croton Point Nature Center. The oldest oyster shell middens on the North Atlantic Coast uncovered by archeologists on Croton Point confirm that the peninsula was inhabited by Native Americans as early as 7,000 years ago. Croton is in fact named for the Indian sachem, Kenoten, which means "wild wind.” In the 17th century, Indians of the Kitchawank tribe on the Wappinger Confederacy occupied a large fortified village on the high flat at the neck of Croton Point, which they called Navish. This was one of the most ancient and formidable Indian fortresses south of the Hudson Highlands.

    Croton Point Park

    Not too much to offer

    General: A county park with a mix of w/e (6 sites) and FHU sites plus about a dozen tent sites near a capped dump! There is a lodge and cabins close to the end of the point, but they appeared to be part of a group camp experience. They all appeared to be closed for the season (or because no one was renting at the time; they reminded me of places I used to take youth groups for weekend camps). The reservation process is a bit wonky. You need to call (no online reservations) and then wait for an e-mail, but the e-mail does not tell you your assigned site; you have to wait until you check in to find out your site.

    Site Quality: We had a loosely defined gravel pad that was level. All sites appeared level. The FHU sites were back-to-back and although there were trees separating the sites, they were close together. No one was in the tent sites, but they did have new picnic tables.

    Activities/Amenities: Other than a playground and a basketball court, there did not seem to be any activities to partake in. There used to be a pool but from the looks of it, it hasn’t been in use for many years. There are walking paths outside of the campground that are located within the park, but we did not have time to explore them. 

    Bath/Shower house: Clean but a bit dated. No shelves or hooks for toiletries. I was surprised the door was left open all night long. There was a sign warning that the toilets were slow flushing, but I think this may have been fixed because the flush was so powerful that the water splashed over the top of the seat! 

    Because it was on a point on the Hudson, I had hoped for views from the campground but there were too many trees to see the water. I was perplexed by the signs throughout saying no trespassing/fishing prohibited. I get the no fishing part but the trespassing? When we checked in, we had to write down our credit card number on a slip of paper before we were given a key that opened the gate to the campground. When we checked out, we asked for the paper or to watch it get shredded but were told they had to keep it on file which concerned us.

    Campgaw Mountain Reservation

    Busy but Lonely

    Campgaw doesn’t seem to offer much in terms of a camping experience. The sites themselves are fairly close to the road and there are super popular hiking trails that run right through all the camps. If you like being woken up by folks walking their dog at 7 AM, this is the spot for you.

    However, once the sun goes down, the campsite becomes a ghost town (except for the odd sheriff driving down the road). We went on a holiday weekend, and we were the only campsite that was occupied, so that is absolutely a plus. There was also plenty to do during the day, like joining the hikers on those trails, disc golf, and sitting by the water.

    All-in-all, it is not a terrible site, especially considering the cheap price.

    Clean bathrooms, good amenities

    Stay in one of the last weekends of August.  We were a party of 8 so we needed 2 sites, the first sites we booked were horrible - so so tiny (E11 & E12) and right on a swampy pond where the grass is growing into the water so it was hard to see where the water line was.  We had kids, so we needed to move our sites.  We ended up right across the way on E7 & E8 - much better.  This loop for tent campers is mixed.  Some of the sites are literally on the road - stay away from the sites on the same side of the road as the pond.  I saw a family who literally had to block the road a little bc they couldn't park their car *and* have a tent on the tiny site.  Anything on the side of E7 is bigger and a little deeper into the trees, but nothing seemed to be private in this campground.  It was a busy weekend, so of course there was loud music and partying - it just so happens that it was next door to our sites.  Bathrooms were far on this loop.  There are little foot bridges that you could take to get to the bathroom easier (and closer) but they are set on people's campsites, so if someone is on that site it's really walking through their site to get to it.  The campground has good amenities - wifi, pool, jumping ball, playground, basketball courts, volleyball courts, and a tether ball court :).  Great for the kids.  Pool is small but it works.  There's a cafe there so we were able to grab coffees and stuff.  They deliver wood and ice to your site which is super convenient.  We would return for sure.  Also - just to let everyone know the fire pit is really small.

    Lake Frederick Outdoor Recreation Area

    Beloved Family Spot

    Yes, this is a military-only campground but, that doesn't take away from how incredible it is and that is properly advertised. 

    This place is incredible.  Being military-only keeps standards high, the campground clean and well maintained.  We've spent years here, with Dan & Janet but, are looking forward to returning this year under new management, as they enjoy retirement after many years of hard work. Boy, does their hard work show! They have poured so much love and attention into the building and maintaining of Lake Frederick! 

    Between rustic power-only campsites that give you a true camping experience and upgraded but, still simple cabins which allow campers of all ages and abilities to enjoy the outdoor experience, there is something for everyone.  The new docks around the swimming area create a safer swimming experience for even the most inexperienced swimmers, allowing them safe and obvious perimeters.  The bath house is always well stocked and clean, ready for end of the day cleanup and the laundry facilities are a great bonus for those of us who like to stay longer than a couple days.  

    You won't want for anything at Lake Frederick and it will be a great way to unplug, kick back and enjoy God's Creation!

    One of my favorite stays!!!!

    When we rolled in, I got the feeling we were going to really like this place. It turns out, I was right!! They have the best staff and they are everywhere, if you need someone they are always around and super friendly also. They have a pond for fishing, basketball, a mini golf course being redone, jumping pillow, 2 pools, arcade and a playground. The sites we stayed in had a lot of trees and not on top of people. You can tell they maintain the campground and do their best to keep everything clean and they do a great job. They had a free pancake breakfast on the weekend days, and a band Saturday night.

    Around the area, there is tons to do if you're an outdoors person. They have an awesome path called the rail trail that you can ride your bike or walk down it goes for 22 miles, and you can stop on the way in little towns or for a bite to eat. They have a wonderful state park with a huge waterfall not a bad hike but 20 mins from the car, and a huge lake if your travel up the mountain. The hiking in the area is for all levels and ages. If you like to be outside, you won't be disappointed.

    I love this campground, my family and I come every year. Super clean, friendly staff and lots of entertainment. We have seen live music and they have free breakfast events. Lots of activities for the kiddos. I have stayed in every corner of this campground but my favorite sites are the 30’s. Full hookups, back in, lots of trees and really roomy. Lots to do around like New Paltz, Mohonk Preserve, Lake Minnewaska and my favorite hike Bonticou Crag…

    First time camping in awhile; great time

    We chose Korn's because it was close to home on our first trip in years.

    It was a great time from check in to check out.

    We had a nice tent site ( 92 ) along the river. I called myself captain planet because I fished a coffee cup from the river.

    Will definitely be staying again

    My first TT stay and it's better than expcted

    This was my first stay at any TT campground and I wasn't sure what to expect with this campground as the reviews are so mixed. While I don't have other TT campgrounds to compare this to, I do have a lot of experience in state parks and private campgrounds. If you are looking for an RV resort-type place, this isn't it. If you are looking for a CAMPground, this is a wonderful place! The grounds are well-kept and the bathrooms are clean. Th campground itself is pretty quiet, although there is some noise by the playground. Once school is out, I'm sure it will be busier.

    The only problem I had was that my Starlink didn't work at the first site (372 - full hookup) but they let me choose another site (435 - no sewer) and I was happy as a clam. Oh yea, the sewer connection in 372 ran uphill for me, but my pipe sits very low.

    Skyline RV Park

    It is not as lovely as it looks in the pictures

    There was only 1 bathroom with small shower for all guests, however they are in the process of adding 5 more. The only bathroom did have toilet paper, a garbage can and hand soap for the sink, but no paper towels to dry your hands and no shelves, hooks, or benches to put your things while you shower.

    The campground was pretty hard to find. We almost gave up before we found someone local who could point us to the right place. One of the reasons is that their sign is half gone, small, and very hard to read.  

    The views of the city are spectacular, but the place itself is what I would call very rustic/primitive/not lovely.

    The host was helpful but the administration seemed a little unorganized. When we tried to check in, they told us we were a day too early. I had booked through the Dyrt and there was a mixup. A day later, two days later, they texted us that we were late checking in. They had another mixup. On checkout day, we didn't check out on time and they didn't contact us until it was so late we had to pay for and stay another night. It was our fault, but a reminder of checkout time would have been helpful.

    I have pictures I would add if there was a way to do that.

    Liberty Harbor RV Park

    Close to NYC!

    This RV park is literally just a parking lot and quite expensive for what it is.

    The location is great, but the surrounding streets may be hard to maneuver with an RV if you’re a newbie. You can see the Statue of Liberty from the park, and there were several cafes and restaurants within walking distance.

    If you’re looking for actual amenities, this probably isn’t the park for you. But if you just need a base camp for doing tourist activities in NYC then this place will do.

    There is 24 hour security which is nice as well. We felt safe while we were there, but it was also fairly empty too.

    Winding Hills Park

    Gorgeous in the fall!

    We were there in late October, towards the end of the season, and there were only a few other campers there, and it was a weekend! So nice to have the whole place feel so quiet and desolate. No reservations taken other than for certain popular holidays. You just show up and pick a spot and the ranger will come around and collect fees. For non-residents the non-electric sites are $40 and the power sites are $45. Residents are $10 less. Cash only!

    No privacy between sites, but sites are big and far away enough from each other that it felt like it would be ok. Lots of trees everywhere, which is nice. Some sites are really nice, with a little driveway to go deeper into the woods and off of the main road. 

    Dump and potable water fill available here. Dump is kept locked, but there’s a number to call and staff will come unlock for you. Water spigots available throughout campground. 

    Good cell reception for Verizon and ATT. Showers are free and hot and clean, water runs continuously (no button to push), and you can adjust the temperature. 

    Gorgeous lake for fishing or just enjoying the beauty. Beautiful place. We were there at the end of October, and staff told us Oct 22, 2023 was the last camping day of the season.

    Well maintained and friendly

    Ive been coming here for years. They have great sights and are open all year round. Ive stayed in hammocks, tents, leantos, and even did a good share of car camping. They have many sites and a tone of hiking trails. All of the shelters have fire pits and some have interior fireplaces. The one downside is that you need to book in person but it can be done well in advance if need be.
