Definitely need a decent sized boat with a gas outboard to get there, but wow. What an experience. Me the wife and our 3 children had an amazing time on our three night stay. Definitely no amenities other than an outhouse but spectacular views and pristine waters. Great fishing, lots of fun to be had on the water and quiet peaceful evening by the campfire. Will definitely be going again in the spring.
When camping on lake George, staying on an island to camp is a must-do. We rented kayaks and actually reserved a spot on our own private island. It was little, slightly wooded, and private. There are also other islands in the park - Glen and Long, etc, where there are more sites in a group setting, but nothing beats being alone and hearing only the tide crashing next to you all night. We went for July 4th and got front row seats for their fireworks over the lake from our private shore. It was beautiful. Spent the rest of our time kayaking, swimming, hiking in the mountains and eating at our favorite local joint, George's (we recommend the prime rib and salad bar with their carrot slaw - it's amazing.) Best kayak rentals at Bolton Landing a short drive down the coast!
