Lake McDonald
Lake Largest lake in Glacier National Park with dramatic scenery
The largest lake inside Glacier National Park, with historic Lake McDonald Lodge, boat tours and trailheads leading to alpine hikes along its western shore.
Lake McDonald is a long, narrow lake in Glacier National Park in northwestern Montana and is the park’s principal lake on the west side of the Continental Divide. It is known regionally for its shoreline views, clear water and accessibility from the park’s west entrance.
The lakeshore includes the historic Lake McDonald Lodge and a small cluster of visitor facilities near Apgar on the west end, which serve as the main access point for boating, kayaking and lakeside walks. Scenic drives along the road to the lake provide frequent viewpoints.
The lake lies within Glacier National Park and has been part of the park’s visitor infrastructure since early 20th-century development of lodges and access roads for tourism.
Geographically it sits in the western valleys of Glacier National Park, Montana, with the community and visitor facilities concentrated at the lake’s western end near Apgar and the Going-to-the-Sun Road corridor.
- Historic lodge: Lake McDonald Lodge sits on the lake's shore and is a historic focal point for visitors, providing accommodation and boat access to the lake.
How to Get to Lake McDonald #
Lake McDonald sits at the western entrance of Glacier National Park (near Apgar). By car, drive from Kalispell on US‑2 to West Glacier and follow signs into the park to Lake McDonald; the drive from Kalispell is about 30 miles and typically takes around 30-40 minutes.
Seasonally Amtrak’s Empire Builder stops at West Glacier (summer schedule); from the West Glacier/Apgar area the lake is a short drive (10-15 minutes) or reachable by park shuttles/tours that operate in peak season.
Tips for Visiting Lake McDonald #
- Enter from the west (Apgar Village/West Glacier entrance) - Apgar has the main parking, visitor facilities and lakeshore trails that put you right on Lake McDonald without needing to drive far into the park.
- Visit at sunrise or early morning for calm water and dramatic reflections of the mountains; this also avoids the mid‑day wave of tour buses and Going‑to‑the‑Sun Road traffic.
- If the park shuttle is running in season, use it or arrive before 9:00 a.m. to secure lakeside parking; take the Lakeshore Trail east from Apgar to reach quieter stretches and viewpoints most day visitors miss.
