Parking
Begin at Goat Haunt Ranger Station. Boat passengers follow the paved path from the dock; the area is reached by watercraft or backcountry trail rather than a drive-up trailhead.

Glacier National Park, MT
A short forest walk ends at a waterfall beneath high peaks.
Overview
Rainbow Falls is a 2-mile out-and-back from Goat Haunt Ranger Station, listed as 1 mile each way. The route follows Waterton Lake Trail for most of the walk, then branches onto Rainbow Falls Trail to the cascade. Budget about an hour on foot; its short distance makes it an easy side trip if you are already at Goat Haunt, but getting to the remote start takes more planning than the hike itself.

The highest, rockiest slopes around here are a summer buffet for grizzly bears.

Most of the approach runs through forest. A route description places Cleveland Creek about 0.2 mile in and says the walk then follows Waterton River before the falls; it does not say whether the creek crossing is bridged. The mapped line is about 0.96 mile to the falls, close to the park's rounded one-way mile. The current trail detail reports 172 feet of gain and 108 feet of descent on the approach, so expect some short ups and downs.
A natural mineral lick lies along the route, and deer are often seen there. At the end, water tumbles across layered gray rock, with tall conifers and distant mountain peaks in view. Frame the cascade with some of the trees and peaks so the picture keeps the setting as well as the water.
All hikes in the area start at Goat Haunt Ranger Station. Boat arrivals walk a paved path from the dock; the area can also be reached by backcountry trails. Hikers going beyond the station must report their U.S. entry under current CBP rules; the short round-trip ferry exception applies only to visitors who do not hike past the station. Arrange reporting and boat or backcountry logistics before leaving Waterton, where there is limited cell service along the lake. The station lists drinking water and a seasonal restroom; food service on the route was not established.
Pets are not allowed on Glacier trails. The park warns visitors to take care around water, steep drop-offs, and wildlife; give animals at the mineral lick plenty of space. Check current boat and trail-status information before setting out; access and conditions can change.
