Only rideable once the snow pack has melted.


A seriously well-crafted trail. The DLRT, when completed, will circumnavigate the high country around Donner Lake. A 23 mile loop is planned, about 9 sweet miles are open to bikes so far. Enjoy!

Need to Know

This trail can be shuttled several different ways. For mostly downhill fun, start at castle valley (TH) and end with the shuttle at Wendin Way Access Trail. For a fun long ride, start at Castle Valley (TH) and end with the shuttle in Truckee (Tahoe Donner) and combine Hidden Gem and Motherlode. My favorite is a crusher: combine DLRT with Emigrant Trail , and if you are sick in the head, do Hidden Gem and Motherlode along the way...


Starting at Castle Valley Trailhead, head up the fireroad the same as you would for Hole in the Ground. Before Hole in the Ground trail, there is a right turn after a rock garden on doubletrack. Stay on the doubletrack, cross over the PCT (no bikes), and the summit trail (no bikes). At 1.2 miles, the DLRT starts to your right. Soon after, the granite garden begins - it's one of the best sections of trail featuring great vistas of the Donner area.

At the 3 mile mark you'll be at summit lake. From here, there is a faint trail around the lake and several cool perches for a snack break. Start on doubletrack at the lake and follow it up and over a small hill. Then head downhill toward Truckee for a wicked descent. Keep an eye out for a short climb to the left at about the 4.4 mile mark, the singletrack picks back up on an exposed hillside. You'll pop out on a doubletrack again for a short climb, then back onto trail on the right.

After crossing a bridge, you'll arrive at an intersection with Wendin Way Access Trail. Left continues up to the ridge, right takes you down to the trailhead. Once up a short grunt of a climb, you are on the ridge and in Tahoe Donner area. From there, you can take DLRT on a fast plunge down to the "bench" or delve into the Donner trails, the possibilities are endless. The DLRT also functions as a great out-and-back. Head back the way you came! Its ALL good...

Overrated imo. Close to freeway, decent chunk of descending on fire road and the final descent is one that is just like many other 'ok' trails.
