A tough, but scenic all-singletrack loop around the tranquil and pristine Waldo Lake.

Features -none-

Although the snow melt at the high elevation lake will be gone by late June, the mosquitos can be relentless throughout the summer months. Best bet is to plan a ride here after Labor Day if possible.


Waldo Lake, with a surface elevation of 5414 ft., sits in the heart of the Central Oregon Cascades. This beautiful lake is encircled by a challenging 21 mile singletrack loop, the Jim Weaver Loop Trail (aka, Waldo Lake Trail #3590).


The elevation gain of the overall ride is manageable, however the relentless short, steep climbs and technical sections will give you a quite a workout. There are incredible views of the lake throughout the ride and plenty of spots to cool off during the hot summer months. Pick up the Waldo Lake Trail from the main parking area at the northeast corner of the lake and complete the loop either clockwise or counter-clockwise.

History & Background

The lake is termed ultra-oligotrophic as it has extremely clear water and very little organic material. Nutrients required for sustained plant life are not present as the lake has no permanent inlet. Depths of over 100 feet can be seen on a clear day and Waldo Lake is in fact one of the purist lakes in the world. Be sure to leave only footprints (and tire tracks!), take only pictures.

Counterclockwise, stopped at South launch for a great rest before the final push home. Loved the last 3 miles of downhill. Definitely a strong blue. 22.3mi

Only one deadfall tree across the trail. It is located in the burn section. First half is more technical, second half smoother and more sustained. 20.3mi — 3h 00m

I rode this loop on 7/12/16 starting at North Waldo heading counter-clockwise. I agree with the other comments regarding the burn section on the north end being the best section. The west and south side had about 8 miles of downed logs and there were a few more miles of downed trees on the east. The mosquitos were bad if you stopped, but not a problem if you keep moving. If/when the logs are cleared this would be a great loop but for now I would suggest an out and back from north waldo into the burn until you hit the logs, probably about 9 miles total. And don't forget the bug spray if you're camping. Jul 15, 2016
I rode yesterday, 8/27/2016 starting at Shadow Bay going CCW. There was only one downed tree to carry over. Mosquitos were only bad in really sheltered areas away from the lake. Late August is definitely the time to go! Aug 28, 2016

7/14/2017 Rode counter clockwise starting on north end of the lake. The beginning of the trail was nice and in great shape. On the west side of the lake was over grown making it difficult to pick a good line, a lot of roots, had a number of muddy crossings, two place where the snow had not melted. Because of this I could only give the trail 3 stars. The rest of the trail was in good shape. Jul 17, 2017
