This trail is open to motorcycles, hikers, horses and bicycles.

This route is sometimes known as the Sawtooth Ridge Epic.

This ride has it all: old growth forest, pristine lakes, great views, very narrow trail, some climbing challenge, a stretch of flowy downhill and to finish a section of steeper downhill with many switchbacks. Perhaps the one thing missing is an actual peak--despite the name, the route does not go to the top of Osborne Mountain. If you want panoramic views, do the three mile side hike up High Rock that's described below. This is a great ride, more people should check it out.

The ride difficulty is in the same class as, but a bit higher than the Lower Dungeness-Gold Creek trail loop. There are some tough climbs, and there are long, long stretches of very narrow trail with side slope exposure.

The adventure consists of a 11 mile approach on forest roads, and a 12 mile return that's mostly singletrack with a short road climb in the middle. The ride can also be done as a point-to-point shuttle. The shuttle makes it a 12 mile ride that still has 2500 feet of climbing.

Big Creek #252 / Teeley Creek #251 trails can be ridden as an 8mi out and back or combined with the Osbourne Mt #250 as a point to point or larger loop using forest roads. Done as an out and back or point to point this ride has steep climbs and super fun single track descents through old growth forest. Three lakes are accessible on the trail along with great views of Mt. Rainier giving this ride a back country feel.

Access Info

The campground is closed and gated from mid-September through mid-May. Access to the trail during this time is from the campground entrance road on Forest Road 52.

Access Option 2:

To access Big Creek #252 trail head start by driving 17 mi north or 2.8 mi from big creek camp on Skate Creek and turn FR84. Continue 4.2 mi up FR84 and turn right on 8420 and the trail head will be on the left in 2mi.
If doing this as a loop or point to point park at Big Creek Campground so the ride ends with a long descent
