GuideVery nice night spent at Winona State Forest with my boyfriend and our dog, Michelob. Lots of horseflies and mosquitoes but big spray did help and the fire. We have a truck bed tent we used for this trip and a canopy tent to put all of our stuff under. Each site does have a fire pit of some sort.
TravelerWe thought the campground was beautiful, tight to your neighbors on majority of sites, and lack of trash cans for pet waste especially since the campground is so big. It has ball field, 2 playgrounds, rec room, camp store, lake Ontario to swim, trails for multi use, and pavillions. Down fall for us was small site , lack of trash cans to toss pet waste, not being told about fill station because there is no water faucets like most state parks along campground. We were there for first time so not familiar with park. Office did not offer us a map to get to our site or clue us in on filling our tank prior to parking camper. Main gate personnel not on same information. bathrooms could be cleaned more often. bathhouse building is all gender with bathrooms on one side of building and showers on other. Bathroom and showers are private space rooms. Beach is very rocky with little sand area. Life guards only guard one side of beach making everyone crowded to one side
ScoutNot very welcoming at night. Kinda creepy.
GuideI've stayed here twice, once in 2024 and again in 2026, both on Memorial Day Weekend. In 2024 I woke to the sound of loons but did not hear them in 2026.
This is a large campground on the shores of Cranberry Lake with access to many hiking trails and other activities. Quite a few of the sites are lakefront but they seem to book up fast. Most of the sites are spaced out fairly well although a few are close and will result in you seeing & hearing everything your neighbors are doing. However, they are mostly designed well and blend into the environment. A few seem like afterthoughts and are right on the road, so you'll want to choose carefully.
Dumpsters are in the center of the campground near the bathhouse, which has hot showers. There is a sandy beach area near the entrance of the campground and a volleyball area near the dumpsters/bathhouse.
It's a beautiful area and is mostly quiet. Other campers were respectful and didn't play loud music although a few talked loudly late into the night. There are lots of trailer camping sites, so you should expect to hear generators although most people were considerate and only ran them in the daytime.
This is a great campground for exploring the Adirondack Mountains. The town of Cranberry Lake seems mostly dead so don't plan on eating in restaurants nearby.
TravelerGood place to fish and stay. Good welcoming friendly host also. Well come back
LegendThis has been one of my favorite campgrounds and I have camped there many times over the last several decades. Always well maintained, but peaceful state forest campground with spacious sites, many right on the water. There is an official beach, but the water sites really have their own access for canoes and nice swimming. The water is crystal clear, sunsets magnificent, canoeing and hiking opportunities abound, and even on a "busy" summer weekend the campground is quiet and the fellow campers are low key and respectful. For a tent camper, this is an ideal location and I love it. Fire ring, even tenting spot, picnic tables, etc. There are numerous accessible campsites, a shower building, and regular restrooms as well as privvies. Small trailers can fit and their is an RV dumpstation, but this is not a campground for big rigs and hookups. The campground is a little off the beaten path and in the further reaches of the Adirondacks for most campers, and the vicinity is one of the largest and most pristine areas in the ADK wilderness. Come well supplied with groceries and camping needs as there isnt much nearby. The SUNY Forestry school maintains a Ranger school at nearby Wanakena on the west side of the lake, and a Field Biology station on the south side of the lake. Nice hiking in the area
TravelerGreat camp. Easy in and out for big rigs. Right on the St. Lawrence River. Many amenities to include 3 bay R.V. wash as well as car wash. Nice sites and some on the water with docks and a boat ramp.
ScoutCedar Point is in a very nice location,our site that I booked was not in a ideal location being on the road to the boat launch, ( my fault ) Camping went fine until the last couple of days when people starting walking through our site, looked liked a group of people who knew each other and we were in their way.
ScoutI love how it has great fishing and nice camp sites even let's you bring a boat nice clean showers and bathroom can easily find firewood near by as well..

Catch some perch and have a fish fry back at camp," reports a camper from Wellesley Island State Park Campground.

Accessible waterfront: Kring Point State Park features waterfront sites on both the river and bay sides.

Free primitive options: Payne Lake offers no-cost camping without amenities for those seeking a more basic experience. "Public access boat ramp with limited parking available on both sides.

We reserved online and there was a mix up. We reserved 3 days got there and found out there was no hookups we were told if we cancelled we would only get a few dollars back," cautions a visitor to Keewaydin State Park.
Site sizing limitations: Verify your RV will fit at your selected site. "We arrived on July 5th for 5 nights.
