To explore the Mission Mountains Tribal Wilderness, first pick up an $8 tribal recreation permit, available at Allard’s Trading Post and other local stores. A map of the Flathead National Forest or the Flathead Reservation is another essential.

St. Mary’s Lake is less than 10 miles from St. Ignatius on St. Mary’s Lake Road. (Find the road just southeast of the mission and follow it as it turns into a fairly bumpy, dusty gravel road, turns left, and heads into the hills.) There are several places to pitch a tent around the lake, and it’s worth taking along fishing gear and a tribal fishing permit; there are some lunker trout around here.

Just over a mile up the road is the first of the Twin Lakes, which are a little more isolated and quieter than St. Mary’s. No motorboats are allowed on the Twin Lakes; St. Mary’s does permit them.
