Trail Information
The Supply Trail starts on the road that leads to Hosmer Grove and winds up through the native subalpine shrubland that dominates this elevation. This is a great chance to see this ecosystem up close and away from the road. Bird watching can be good along this trail. The Supply Trail connects with the Halemauu Trail in 3.5 miles and becomes even steeper as it approaches Halemauu Trail.
