Not that it really matters but Bisco is 7 hours tops from Hamilton.
There's lots of places closer than Bisco, but how many are on a 26km lake that has but one camp, with walleye fishing that's comparable to a fly in?
Also Ray's camp is not on Biscotasing lake. They pick you up in a water taxi, take you to the very end of the lake and your stuff is hauled over to Ramsey lake with a tractor. From there it's a boat ride to the camp.
It's as remote as you can get within that driving range.
I've been to Ramsey a bunch of times. Never stayed at Ray's camp, always camped. There's a rough boat launch in Cat Bay at the north end of the lake. Good for light aluminum boats only..
