Camp ground is large - Navy base during WW II and Air Force base during the Korean War. Visit the Museum at the park.
Sunday morning brunch at Belhurst Castle is always good - reservations are needed - they are busy in the summer.
Two new breweries on the lake
east side of lake Grist Iron Brewing
west side of lake Gael brewing
The gorge at Watkins Glen - all will enjoy.
Wineries - plenty on Senaca and Cayuga lakes.
Corning Glass museum is not too far of a drive. 17 and under are free.
Boat cruise on Seneca Lake - we have done a dinner cruise.
I'll be at the Watkins Glen race track the weekend of June 27 - Sahlen's Six Hours of The Glen. If you are in to auto racing the race is great.
