“A great loop near Clarkia, ID, a forest road climb with a nice singletrack descent.”— Kyle F
Electric Mountain Bikes Allowed
In typical ridgeline fashion, the trail goes up and down (though, mostly down) to the junction with Gold Center Creek - Trail #251. You owe it to yourself to continue along the ridge on a rougher and steeper section of 275 to the summit of Grandmother Mountain where a great 360 degree view awaits you for all your hard work. It will become hike-a-bike for most people up to the summit. Take it all in, have a snack, and enjoy a fun technical descent back to the junction with Gold Center Creek - Trail #251.
From the junction, the trail has a few places that are moderately rough and technical, but as you descend from the alpine into the cedar covered forest below, the trail becomes more fast and flowy. The trail then begins to gradually widen towards the bottom where it eventually links up with Gold Center Creek with huge cedars all around.
Need to Know
IMPORTANT: Despite what the GPS track of our day out there says, I would recommend starting at the bottom of Gold Center Creek - Trail #251 and riding the short flat road (3319) section to Rd. 301 and begin the climb that way!
Begin the singletrack traverse on Marble Divide Trail #275 . In just over a mile you'll reach the junction with Gold Center Creek - Trail #251 , which will be the trail you descend back down. Continue on 275 and approx. 3/4 of a mile you'll meet another junction (signed). Stay on 275, which begins to climb steeply towards Grandmother Mountain. In approx. another 3/4 mile you'll meet the summit spur for Grandmother Mountain. 275 will begin to go down from here towards the saddle with Grandfather Mountain. Take the spur up, hike-a-bike, or leave your bike and enjoy the views up top. From Grandmother Mountain, head back to the first junction with Gold Center Creek - Trail #251 and enjoy a fun descent back down to the start of the ride.
