- Fortress Lake: the park’s main sight, a long, deep lake with opaque blue-green water and sheer walls on every side.
- Chaba River valley: the approach route, with gravel bars, braided channels and spruce forest where moose and black bears leave tracks.
- Lake shoreline camping: quiet backcountry sites with stony beaches, loon calls at dusk and cold wind off the ice.
- Glacier views above the lake: peaks on the Continental Divide side carry hanging ice that drops meltwater into the lake.
- Wildlife watching: mountain goats on the cliffs, grizzlies and black bears in the valley bottoms, and occasional wolf sign on riverbars.
- Fortress Lake Wilderness Retreat: a remote fly-in fishing lodge on the shore, handy to see as a landmark, though it is a separate private operation.
