My family and I have been visiting Old Forge Camping Resort for 20+ years. This is one of the most family friendly resorts and a perfect weekend getaway for those living in other parts of New York State. The visitors/welcome center has everything you need, including firewood, sweatshirts and homemade breakfast sandwiches. There is endless RV camping, tent camping, cabins and cottages available. Make sure you book far enough in advance. We typically book 1 year prior for the cottages.
The bathrooms and grounds are well maintained and accessible from wherever you are in the park. There are hiking, biking and running trails galore. A volleyball court, playground and even a lake to fish or rent paddle boards. There is a bus from the campground that takes you to enchanted forest safari, which is a great way to avoid parking. Would recommend 100%
