What Gangster said. Cassel is where most of the fly fishers camp. Local flyfishing clubs often meet there as well. I like to camp up at the forest service campgrounds as I like to play in the smaller stream section and harass the Brookies, but they close most of them when it gets colder. Cave is usually open till the end of October. Last year at this time it was 22 degrees in the am when I woke up.
I am planning on going next Sunday-Tuesday depending on weather.
Bill put a post in the Campgrounds section on Burney area camping and lodging for more info.
