Cayuga Lake State Park has a massive campground but most of the sites don't have water or electricity and are squeezed together in tiny loops. If you stay, I'd recommend the 800 or 1000 loops--the sites were much bigger in those areas. But we stayed in the 100 loop (appropriately named "Minnow) and ended up leaving early because our neighbors were just too close for comfort. 

The lakefront area of the park was very nice and we enjoyed walking on the drive down in front of the lake. Plus, Seneca Falls is an adorable town and it was great to visit the Women's Rights National Historic Park and the homes of Elizabeth Cady Stanton and Harriett Tubman, while we were in the area! 

To be fair to this park, we came directly from Watkins Glen State Park (which we loved) and our neighbors were rambunctious. We may have had a better opinion, had the circumstances been different. And in any event, we did really enjoy the area but decided to leave after 2 nights (rather than the 5 we had booked). 

Oh and if you have a boat--the dock area of the park seemed really nice. We'd have loved to get out on the lake!
