Trail Guide
There are several possible routes to the summit of Mount Agassiz. These are a few:
The shortest route is via the West Face Direct Route. This is a short, steep, and very direct route. The boulders can be tedious, but the route is not difficult. This route is about 7 miles round trip. The route usually takes the better part of a day. On the way up the saddle of Mount Agassiz you will find two ice caves. These secret caves may look small by the holes, but they both go deep - one going almost 50 feet down! There are some small parts parts to squeeze through, so if you are overweight at all, you might not be able to go down to far. Go to our Cave Exploration page for more information on the ice caves.
The most popular route is probably from Naturalist Basin. It is probably the easiest route to the summit of the mountain as well. This route is about 14 miles round trip and takes one long or two shorter days.
Grandwazoo has added a Loop Route from Hayden Pass which is about as short as the West Face Direct Route. The route ascends the NW ridge of Agassiz and descends a variation of the West Face Direct Route. This route is about 7 miles round trip and takes the better part of a day.
The final route discussed is the one from Christmas Meadows/Stillwater Fork. This route is very similar to the route up Spread Eagle and connects with the Natuarist Basin Route after reaching the col east of Agassiz. This route is scenic, but is longer than the other routes described, being almost 25 miles round trip.
The routes up Agassiz also connect quite well with those from Spread Eagle and Hayden Peaks from Christmas Meadows/Stillwater Fork, since the same cols/passes are used. Many of the routes on those pages connect with the ones described above.
Once you are at the top, you will find a mailbox with writings of everyone who has been to the top. Make sure you sign it! Camping is available all around Mount Agassiz. Popular places to camp includes Jordan Lake.
