“The world famous Rubicon Jeep Trail connects Lake Tahoe to Loon Lake.”
— S. Lengyel
Rubicon Jeep Trail is an iconic destination for 4x4s. The Tahoe side of the Rubicon is also decent for MTB, and can be used for longer backcountry rides and loops.
The terrain ranges from easy to steep climbing on loose cobble.
Parts of it are very scenic, and there are three alpine lakes along the road.
Note that beyond the Blackwood Canyon intersection the trail is not great for MTBs. Think big rocks and deep powdery dust. Great for rock crawlers, not so great for MTBs.
The Rubicon is mapped to the top of Cadillac Hill, but very few people ride that far. You certainly can ride from Loon Lake to Tahoe on the Rubicon Trail but it is slow going on bikes due to unrelenting rocks. It took some of my friends 8-10 hours to cover the 26 miles, and me several hours on a motorcycle due to scouting the moto-accessible lines.
