Summit Lake via Johnson Canyon: A California 89 Bike Guide

Start with the place

Johnson Canyon sits near Donner Summit by the Donner Lake exit off I-80. It is close to Truckee, but the route climbs into higher Sierra terrain where rocks, bridges, weather, and late-season snow can all shape the ride.

Summit Lake gives the day a clear destination. Think of the lake as the pause point, then remember that the way down follows the same rough ground you climbed.

How the ride feels

Summit Lake via Johnson Canyon asks for patience on the way up. The route has rocks, bridges, road links, and a lake turnaround, so it never feels like just one long grind.

The descent follows what you climbed. Pay attention on the way up so you know where the rough spots are on the way down.

Finding your way

Park at the Johnson Canyon DLRT lot by the Donner Lake exit off I-80.

Ride through the trail and bridge sections toward the dirt road. The route joins the road, leaves it, joins it again, and then climbs to Summit Lake.

Save the map before you start and bring a layer for Donner Summit weather.

Who this ride is for

Pick this ride when riders who can handle rocky climbing at a steady pace.

Beginners may find the rough sections hard to enjoy. Bring a snack for the lake and enough time to make the turnaround feel worth it.

Keep it local
