Osborne Mountain

Osborne Mountain Professional Review and Guide

"This is another advanced mountain biking loop that can be categorized in the gonzo/abusive realm. The climb that never ends really does find a stopping point —it just takes awhile. And gads! The scenery is spectacular.

Right between Mount Rainier within the Sawtooth Ridge, this route is both challenging and rewarding. The descent is filled with switchbacks and requires a lot of technical skill, wiping out any unsuspecting mountain bikers if they aren’t careful."

The weather was good and the trail was easy to access. My crew and I made our way up the trail. The first half mile presented with patches of thick / slick mud. We made good time...the trail was well defined but was a bit steep. Into the second mile we began to run into traces of snow at about 3200 feet in elevation (starting elevation is about 1800). By 3600 feet and just 200 feet from the trails summit we lost the trail. This was due totally to the fact that anywhere from 14" to 3 feet of snow was present. To further impact us was blow down (very extensive) that covered the trail for as far up, what we guessed was the trail, as we could see. So we were only able to make a round trip of about 4.5 miles. As we came out...the trail is only sufficiently wide enough for an individual...and we encountered several families with small children coming up the trail toward us...be cautious.
