About This Route
St. Mary Lake, Glacier's second-largest body of water, dazzles with vibrant turquoise hues and stellar fishing for cutthroat trout and whitefish. Boat from Rising Sun or fish shores near Wild Goose Island overlook via Sun Point Trail. NPS mandates: no bait except unscented artificial lures in some areas, attend rods closely, release bull trout. Open year-round for lake fishing, standard season late May to November 30. Access via Going-to-the-Sun Road; shuttle recommended during peak summer traffic.
Safety Considerations
High winds whip up quickly, creating whitecaps; never boat without checking weather via NPS app. Steep drop-offs near Sun Point demand caution, especially for kids. Mosquitoes swarm in July; use DEET-treated clothing. Grizzly bears frequent fish-rich shores; process catches 100 yards from water and store in vehicle trunks. Lightning strikes common on exposed points; descend immediately at thunder. Water rescues rare but possible; all on boats wear USCG-approved PFDs per REI guidelines. Invasive lake trout threaten natives; report large catches to park biologists.
Essential Gear
Equip with Ursack bear bag for overnight, Patagonia Torrentshell rain jacket, Sage fly reel, 20 lb fluorocarbon leader, compact stove for hot meals, and emergency bivvy sack. Rubber-soled wading boots prevent slips on volcanic rocks.
Tips for Success
Troll spoons from boats or nymph droppers from shore. Follow catch limits to protect bull trout populations. Practice Leave No Trace by packing out all waste.
