Big Arm Unit- Flathead Lake State Park Campground Professional Guide

Detailed Trail Description from our Guidebook

"Set between the Swan and Mission ranges to the east and the Salish Mountains to the west, Flathead Lake is a sparkling northwestern Montana jewel carved thousands of years ago by receding glaciers. At 28 miles long, it’s the largest freshwater lake west of the Mississippi and draws 80 percent of its water from a watershed larger than the states of Delaware and Rhode Island combined.

No wonder so many people drive up to “the Flathead,” stopping at the highway stands selling Flathead cherries (be sure to check one out—you won’t be sorry). These prized cherries thrive on the microenvironment created by the lake. But visitors don’t stop for long; they’re on their way to a recreational heaven for boaters, anglers, swimmers, and just plain loafers."
