Olallie is one of the few mountain bike trails in the area with plenty of vertical, vistas, and velocity. Designed by Evergreen MTB Alliance, this trail is ranked as a Blue Square and boasts a hefty 19 miles (roundtrip) up Mt. Washington. The trail grade is rarely steeper than 10%, has minimal roots and rocks, and plenty of mossy, green views. Olallie has a ripping fast descent through old growth forest with smooth surface tread, enabling you to push your speed limits. This trail is great for riders of all abilities.

Important Reminders:

There is no water available at the park, so make sure to bring your own.


You can leave a backpack in the clearing or take it with you, but a bit of food always helps if shaken up from a fall or worn out from the heat.


If you are with kids, STOP WHEN THEY ARE DONE!! From all of our instructor experience here at Compass, we have found this to be one of the most important safety decisions. Pushing kids for one last lap or ride when they are tired and/or dehydrated can turn a fun day into a bummer.


If you are still unsure about your time at Duthie, or just want more information and support while riding, Compass has instructors who love to guide groups at the bike park.


This progression is simply a guide, and you are responsible to ride at your own ability and judge your comfort for each and every aspect of the terrain. No matter how aware and careful you are riding, there is always the chance of injury when mountain biking.
