Lake McDonald Valley, Glacier National Park Professional Review and Guide
"Lake McDonald is the longest and deepest lake in the park, carved 472 feet deep in places and 10 miles long by glaciers. The sparkling clear waters and prominent mountain views no doubt contribute to the lake’s continued popularity. This well-used area has been developed with four campgrounds, the west side visitor center, visitor services at Apgar Village, and an amphitheater. Historic Lake McDonald Lodge is near the head of the lake, where a boat tour is available. Going-to-the-Sun Road traverses the southern boundary of the lake. This road provides easy access to the lakeshore and banks of McDonald Creek, which empties into the lake.
There are easy woodland trails to be pursued in this valley, including paved trails at Apgar Village and Avalanche Creek. The National Park Service conducts interpretive programs and guided hikes in the area. The Lake McDonald Valley sits just beyond the West Glacier entrance station and can be reached from the east, via the Going-to-the-Sun Road over Logan Pass. This eTrail provides detailed information on family-friendly things to do. The destinations include: Apgar Village, Visitor Center, and Campground; Apgar Bicycle Trail, Rocky Point Hike and McDonald Lake Trail, Camas Creek Road, Huckleberry Mountain Hike, Lake McDonald Lodge, Sacred Dancing Cascades, and Trail of the Cedars and Avalanche Lake Trail."
