Marble Mountain

Marble Mountain Professional Review and Guide

"The trip up Marble Mountain is an intermediate-level ride with advanced-level views. The 13.2-mile route is a reverse lollipop configuration, with the sweeter part on the stick!The out-and-back sections leads to the top of Marble Mountain, which, on a clear day, provides views of nearby Mt. St. Helens, and also Mt. Rainier, Mt. Adams, Mt. Hood, and other high Cascades peaks and ridgelines.

You've got to believe what I'm telling you here; on the day of research it was cloudy enough that I was only able to see the lower part of Mt. St. Helens to the north. On a clear day, it dominates the views along the way. An added bonus on this ride is that you both begin and end with a descent! Some of the best non-singletrack riding in the area, with some of the best views."

Road 8312 was washed out requiring a detour from 83 down Willow trail (a short XC ski-single track gem) back to 8312. The grind up 8312 is a 6+ mile 1500 ft climb on gravel road with drop-jaw views of St Helens, Adams, Ranier and Hood. As always, come prepared with a USGS map and compass. An odometer etc helps. We did an out and back and logged about 17 miles due to a missed turn on the switch-back at mile 4+. Resist the temptation to go straight unless you want to contour east and take in another beautiful view of Adams. Otherwise, take the left swithchback onto the gray crushed rock road to the top.
