The remote locaton is the best draw to this peak. This peak is above one of the most beautiful alpine lakes in the Selkirk Range. Although the trail hike is only 2.5 miles, it is in a very remote place with excellent views in all directions.
From Sandpoint Idaho head north on US 95 toward Bonners Ferry. Drive 10.5 miles, cross the Pack River bridge and turn left on Pack River Road No. 231. Drive 20 miles and look for the small Trail N0. 217 at the trailhead on the right side of the road. The trail climbs fairly steady following an enoding jeep road. There are 2 stream crossings for water. Large slabs of granite are visible most of the way. Stay on the trail until the lake comes into view.
Harrison Peak can be reached from Bonners Ferry as well. Turn west at the City Center sign onto Riverside Avenue. The City Center sign is just north of the Kootenai River Inn on US 95. Follow Riverside Avenue for 5.4 miles to the Kootenai National Wildlife Refuge. Continue past the KNWR on the paved road for 1.3 miles. Turn left onto signed Myrtle Creek Road 633. Travel 13.6 miles to signed FR 2409 which is the Upper Myrtle Creek Road. Turn right and travel 1.4 miles (with one switchback) to the end of the road. Harrison Lake Trail 6 begins here. There is parking for 6-8 vehicles. This route provided by montanaboy. Thanks.
No fees or permits required. The road to the trailhead usally does not open for vehicle unitl around the end of May or begining of June. Even in the summer a high clearence vehicle is recomended. The road for the last 5 miles or so is unmaintained.
May through October would be the best time. The peak itself is climbable any time of year but access to the trailhead is impossible in the winter. (unless you fancy on hiking an extra 5 miles in deep snow)
Camping is allowed. There are several good sites at Harrison Lake. Most use this are as a base camp. Camping on the mountain itself is impossible due to steep, loose scree and rockfall hazards. The lake is frozen well into June.
