Garden Wall, Alpine ridge in Glacier National Park, Montana, United States.

The Garden Wall is an arête, a rock spine rising from Logan Pass and running north along the west side of the Continental Divide for over 5 mi (8.0 km) to Granite Park Chalet. Its crest reaches 2,285 m, with layered grey and dark brown rock in horizontal bands, steep cliff faces below, and small snow patches in gullies. The Highline Trail traverses it, and the Going-to-the-Sun Road passes through its northwest portions.

The Garden Wall is an arête, a rock spine left standing between two glacial cirques that eroded its flanks. It runs along the west side of the Continental Divide, rising to 2,285 m in Flathead County, Montana, with Mount Gould (2,905 m) about 2.5 km to the southwest. The Highline Trail follows it north from Logan Pass for over 5 mi (8 km) to the Granite Park Chalet.

The Garden Wall forms the divide between the Many Glacier area and the Lake McDonald valley, and the Highline Trail runs along its crest for over 5 mi (8 km) to the Granite Park Chalet. Hikers can take a 2 mi (3.2 km) round trip up the Garden Wall Trail to Glacier Overlook, which looks down on Grinnell Glacier.

The Highline Trail offers the main access route to view this formation, passing through open meadows and rocky sections at higher elevation. Weather conditions can change rapidly at this altitude, so warm layers and rain gear are essential regardless of the season.

Water cascades down the cliff face at the Weeping Wall, a section where the Going-to-the-Sun Road cuts across the formation and creates a striking water feature. This cascade flows year-round but appears most dramatic during warmer months when snowmelt increases the water flow.
