You can paddle to town from Finlayson PP easily, especially if you put-in at the park beach, which btw is a nice swimming spot. Tie up at the town docks. There's also car camping in Marten River PP a few miles south of town. Lots of family canoeing putting in from both parks. If you want to hike there's an old growth trail in Marten PP and another in Temagami.
