From the Rucksack TH, you’ll soon have great views of Mt. Iliamna and Redoubt across Cook Inlet. The trail quickly descends to Bridge Creek and climbs to Crossman Ridge through grassy meadows, often head high in the middle of summer, and forest. There is a bridge over Bridge Creek, 1 mile from Diamond Ridge, constructed in 2019 by the Eagle Scouts. The trail into and out of the Creek is a bit rough; go slow for sound footing. Once up on Crossman Ridge, the trail follows a dirt road to the Reservoir for the last 2 miles.
Distance: 5.0 miles
Elevation Gain: 1160’
Elevation at Rucksack TH: 1155 ft.
Elevation at Reservoir TH: 936 ft.
Elevation at Bridge Creek crossing: 657 ft.
Access: Rucksack TH: There is a small parking area on the southwest side of Diamond Ridge Road where it intersects with Rucksack Drive. Cross Diamond Ridge Road and follow Rucksack to the end where the trail begins.
Bridge Creek Reservoir TH : (up West Hill Road, then right on Skyline Drive 3/4 mile, left on Crossman Ridge Road). Once you cross the dam there is parking on the north side. Continue on foot up the road keeping an eye out for the left onto Crossman Ridge Road.
Level of Difficulty/Grade: Beginning and end are good walking. The middle section, into and out of Bridge Creek, is very rough footing with steep climbs. The bridge at Bridge Creek is a very nice rest stop. The section from Rucksack to Bridge Creek may be hard to find in mid-summer due to tall grasses. Trail signs at regular points along the way. Some very muddy spots. The last 2 miles of trail follow Crossman Ridge Road so be aware of vehicles (which are rare). Bears are uncommon but be bear aware.
