The Blue Lake Ridge Trail (#271) is an 11.7 mile horseback riding trail that leaves the trailhead on Road 23 and climbs steadily through dense conifer forests. The trail crosses several roads before coming to Blue Lake (at mile 3). The heavily used trail proceeds along a rolling ridge, passing by Mouse Lake before descending to Trail #270. This trail has been reconstructed to ATV standards. A short section of the trail above Blue Lake is Hiker Only to minimize noise near the lake. Other users must use Jumpoff Trail #271A and Bishop Ridge Trail #272 to continue the loop. Blue Lake is at the headwaters of Blue Lake Creek.
Overall, Blue Lake Ridge Trail is the 12th most popular horse trail of all 32 horseback rides in Washington.
