If you can i reccomend scoping out sites before you book. Some are hike in, some pull in, some are more for groups/rv. Canopus lake is gorgeous, you need a permit to put you boat down and you don't launch at the beach… you launch up the road a bit. Nice section of the AT runs through. Some easy trails if you want a quick spin. Pelton pond loop is lovely. They just switched their water over to potable last year. Bathrooms are spaced far apart.
Bring your boats! There are a few tent sites where you can launch your boat. I want to live here I love it so much.
Dug it. Not a fan of the platform for the tent. Nice hikes. The view from the lighthouse is worth it.
What a beautiful park. Go river rafting! Only drag is the mixed rv and tent sites.
