What to Expect on the Trail
The Rainbow Trail is an out-and-back route, meaning you’ll return the same way you came. The journey begins immediately with a steady climb through a dense, verdant forest of spruce and birch. The 1000 feet of elevation gain is spread over the 3.5 miles to the turnaround point, making for a consistent, but manageable, incline. The trail surface is generally well-maintained but can be uneven, featuring exposed roots, rocks, and occasional muddy sections, especially after rain or during spring snowmelt. As you ascend, the forest gradually thins, offering tantalizing glimpses of Turnagain Arm through the trees. Around the halfway point, the views truly open up, providing expansive vistas of the water, the dramatic mountains across the arm, and often, the bore tide if your timing is right. The turnaround point is not a distinct summit, but rather a high ridge offering the best unobstructed views, inviting hikers to pause, soak in the scenery, and capture
