    Wellesley Island State Park Campground

    Beautiful campground

    We camp with a big rig(40ft) we prefer the heron loop they are very spacious. Nice bathrooms, a small park near the cabins and heron loop, a huge park near the beach and store. They have a beautiful nature center with a lot of kids activities. A ton of trails, they do have full hookup in another loop. By far a beautiful campground and views

    Soft Maple Campground

    Small and completely gorgeous! Beach, wooded sites, great for everyone.

    Soft Maple is a truly gorgeous small campground. Only about a dozen sites or so, first come first serve. Level sites for RVs or tent or hammock camping. Each site has a nice space with fire ring and picnic table. The beach is lovely and clean. There’s boat access for canoes and kayaks as this is part of the Beaver River route. 

    The entire campground is accessible, with gravel pack paths, and level sites.  

    Charlie is the caretaker here and everyone says he is the nicest person you’ll meet.  You can’t beat site number 11 for the perfect mix of treelined and water view!

    There is space for RVs and a dump station but the sites do not have power or hookups. 

    If you come in to the campground from “number 4 road” (aka state rt. 26) it’s exactly five miles from the Left turn on to Soft Maple rd. If you have time, stop halfway- the 2.5 mile mark will bring you to the entrance for Eagle falls, a short hike with a fantastic reveal.

    Nice State park

    We camped in loop F site 43 with full hookups, nice asphalt pad picnic table and fire ring. Our site is located adjacent to a mowed grass path that leads to the main road, close to the camp store. Beautiful area, lots of hiking and biking trails and swim area.

    Willows on the Lake

    Good Overnight stop

    Mostly long term folks but transient spots have easy road access. Clean bathrooms good WiFi. Sites are gravel, pretty level. Campground is well maintained.

    Birch Haven Campground

    Would not stay again!

    Not really sure what to say about this campground, other than I would not stay here again (thus a one-star rating). It really is not what you would think of as a “campground” or “RV Park.” It is a decent price at $40/night + tax for a 50-amp full hook-up site but it is pretty dumpy. There are tons of seasonal campers that look like they have not moved in years. Most of those units are pretty run down park models and people don’t seem to care. In all fairness, we visited early in the season and many people had not “opened” up their campers yet. There are a few transient sites that you can rent by the night in the center portion of the park. Our site was grassy but not very level. There is a picnic table and fire pit. The electric worked fine and the sewer and water were easy to reach. They do have a rental cottage right on the water which has a great view but couldn’t see inside to tell if it was nice or not. There are restrooms and washer/dryer somewhere on site, but we did not look inside. The grounds seemed pretty well cared for with the grass being mowed and no trash lying about.  Access to the park is easy in and out off route 12 and well-marked.

    The campground is fairly small and not great for a decent dog walk so I found the Zenda Preserve which is a nice hike around a farm field. There are numerous other trails managed by the Thousand Island Lakes Trust that are very nice (we also liked the MacSherry Trail in the town of Redwood). 

    On the bright side, the campground is close to downtown Clayton. There are really cute shops, restaurants, and museums and the downtown parks are great places to watch the sunset. The Wood Boat Brewery brews great beer and has really good food. There are numerous other places to stay for a couple of nights or week which would be preferable.

    Sun Outdoors Association Island

    Island Getaway

    We stayed at Association Island on Lake Ontario in Henderson, NY, for a three-night excursion to celebrate my daughter’s end-of-9th-grade and start-of-summer. We’re so glad we did! 

    When I made the reservation, this campground was a KOA, but has since changed owners and dissociated. They’re owned by Sun Outdoors who was willing to honor the reservation, site request, and discounted pricing.(Thank you, Sun Outdoors!) 

    The approach by way of a single lane bridge to the island is beautiful. Once on the island, it’s obvious that this is a great place for retreat. Surrounded by Lake Ontario, it’s a secluded and idyllic setting for a RV campground. 

    Our site(#G07) was on the sunset-side of the island and the last of the row beside a walking trail. It was wooded, roomy, and has full hookups, a fire ring, and picnic table. I could probably have fit another RV in the site and still had space to stretch. 

    The sites all seem to be well maintained, the campground has paved roadways, a marina for small boats, swimming pool, and ice cream shop. We didn’t explore off the island and didn’t use the bath or shower facilities. 

    Each of our interactions with staff was warm and friendly. We especially appreciate this when staying anywhere. 

    We met a bunch of people who’ve visited the park for several consecutive years- all of whom told us there have been many upgrades and improvements since the ownership change. 

    Except for the 9-hour drive through three states, we can’t wait to return. We paid a KOA-discounted rate of$88 per night plus a$25 site lock fee. We stayed in our 37’ Class-A motorhome.

    Cedar Creek Cabin

    Nice location, for tons of atving!

    Never been up here before, a friend found this place for our lil group. They currently have 4 sites and a cabin, 30 amp electric, water to fill your tank, and a dump station. But like I said the best part is the riding and close to several local bar/restaurants that have good food and good folks. The owners are very nice and helpful and live right close by if you have any issues.

    Cranberry Lake Campground

    Ranger Review: Aftershokz Titanium Headphones @ Cranberry Lake State Park

    As a Ranger for The Dyrt, I am one of the lucky ones who gets gear to review from time to time. We recently tested out the Aftershokz Titanium Bone Conduction Headphones at this gorgeous campground in the Adirondacks! Pretty cool…

    Gear Review

    What we liked most about this product:

    • Versatile: Can be used just about anywhere you want to be able to listen to music or a podcast (without disturbing others), but also want to be able to hear people coming down the trail, birds singing, the ocean crashing along the shore, etc. They are just as great in a library as they are outside.
    • Compact: While they don’t fold down as small as a pair of traditional headphones, they are pocket-sized and can easily be stored in a jacket or a pocket of a backpack.
    • Lightweight: You barely feel them on your head and are very comfortable to wear for long periods of time.
    • Better for Ear Health: Because the headphones use bone conduction technology rather than sit inside your ear, they are much better for the long term health of your hearing.
    • Blue Tooth Technology: Cordless is wonderful…enough said!

    What could be improved:

    • Adjustability: If they were made to adjust to each person’s head size, they would be even more comfortable. If you have a smaller head, they drape down a bit at the nape of your neck and bounce a bit while walking/cycling. They fit my husband’s head perfectly, but are a bit large on me.

    Campground Review

    Wow, what a gorgeous campground! This one came recommended from a friend and we fell in love at first sight. The campground reminded us of summer camp on the lake, as it seemed frozen in time. Each site has a picnic table and open grill and all sites are non-electric. We stayed in site #45, right on the edge of the lake, with great kayak access.

    We spent one day kayaking on the lake and another day hiking. While the mosquitoes weren’t bad at the campground itself, they are terrible on the trails this time of year, so bring your bug spray, or better yet, bug shirts! We’ll need to come back in the winter and do some snowshoeing on these trails, so we can enjoy them mosquito free.

    The bathrooms are kept tidy, the shower house is classic and clean, and there is an extensive recycling facility (yay for NY and ADK!). There is also a sand volleyball court and basketball hoop. Bonus: There was a huge stack of free wood piled near the shower house!

    The Village of Cranberry Lake has some supplies, but not much except the very basics at the general store. You’ll need to head to Star Lake or Tupper Lake for anything of significance.

    We did our usual reservation-less “pull up and see what they have open” style of camping, but during the main season, this place is busy! You’ll definitely need to plan ahead and make reservations if you plan to be here during the crazy season.

    Swan Bay Resort - The 1000 Islands Premier RV Park & Marina

    Great Resort Campground

    I’ll start by saying Swan Bay is a busy, family-oriented campground. We arrived on a weekend and it was pretty busy but loved it during the week when everybody left and things were quieter. Our site (#38) was a Passport America site so we got a great nightly rate of $42 which is half of the regular nightly rate. Our site was a “standard site” near the pool, boat launch, activities, and Tiki Bar which surprised us because sites close to activities are usually desired and not discounted. Campsite costs depends on whether you get a waterfront (which is $95/night even in the off-season), water view, pull thru, or standard site. Most sites do not have shade but they added a new section that does have some old mature trees and sporadic shade. All the sites are the same in that they have paved parking areas with gravel in front, pavers for a patio and full hook-up. Some of the newer sites now have a bit of shade from trees. There are lots of rental park models and cottages close to the pool and Tiki Bar. Within walking distance is a Price Chopper Grocery, Dollar General, gas station, and wine and liquor store.  

    There is a free boat launch and boat slips (not sure if they are free) for guests. I was hoping to spend a bit of time on my paddleboard but soon realized it is very windy here and found very few windows to paddle. Our neighbor (who has camped here seasonally for the last four years) mentioned that he lost three awnings to the wind. So, don’t leave your awning out when you leave your camper and beware of winds if you want to be on the water. Check-in was quick and easy. The park is gated so you get a gate card to enter the park. You also get a BOGO card to use at the Tiki Bar which has specials during the week (like margarita Monday, bucket of beer, bloody Mary’s, etc.). The pool and Tiki Bar were not very busy when we were there. There is a second pool but it was not open yet for the season. In between the pools is a community fire pit with nice Adirondack chairs which is pretty cool. The playground is awesome and huge with lots of cool features for kids to explore. The dog park is very nice and a decent size to throw a ball for your dog. It also has potable water for drinking, which, for some reason, did not work during our stay. There are gobs of activities for kids and adults. Plenty of rentals too – ranging from boats, kayaks, golf carts, etc. 

    A couple of the downsides of this park are the price (unless you get a discount like we did), sites don’t have much privacy, the park gets crowded and noisy, and there was lots of noise from the construction work within the park they were doing. If you are in the back of the park, you get some road noise from Route 12 and the refrigerated truck at the neighboring Price Chopper. Overall, we loved this park during the slow season and during the week when there were not kids running around and adults playing loud music and drinking constantly.
