Time Warp -> Marty's -> BTI Shuttle Map

While Jabberwocky is the most renowned trail in Ashland, if you ask riders who've explored most of the trail network, they often name Time Warp as their favorite trail.


Getting to Time Warp requires a bit of climbing from the shuttle drop off point, unlike the classic Mt. Ashland shuttle run. You'll have to pedal around the backside of the mountain, but on the way up to the top of the trail, you'll enjoy panoramic views from the wide-open meadows, which will make you forget the extra work you're going through.

Time Warp is a black diamond descent with high-speed downhills with long sightlines. While some of the trails on Mt. Ashland are tight and twisty, the high speeds and wide-open ripping on Time Warp offer a breath of fresh air. The black diamond rating comes from the drops, rock slabs, and occasional rock gardens, but if anything, it's a light black rating. Most competent mountain bikers will have a blast on Time Warp, with the expert riders sending all of the hucks and the more timid riders opting for the alt lines.

After dropping out of Time Warp, it's a bit of easy pedaling along the dirt road to return to the main Mt. Ashland trail network. From the Four Corners, the route as mapped takes you down Marty's Trail.

Now Marty's is unequivocally the most technical trail on the mountain, earning its black diamond rating! The upper section of the trail is filled with massive gap jumps that are experts-only. However, they can all easily be bypassed. The middle section of Marty's drops into a steep rock garden descent with technical rock rolls. This is arguably the most technical rock feature on the mountain, earning this ride its "severe" rating. Finally, the rest of Marty's mellows out a bit as it reaches the top of Lizard.

After descending Lizard, this route skips over Jabberwocky and instead heads for the slalom course on White Rabbit with back-to-back berms. Then, it follows Alice in Wonderland on its way to the classic BTI descent.

BTI is a flowy descent with big berms and jumps, but with an old school flavor. It's tighter and more demanding than Jabberwocky, with a narrower trail tread and sniper jumps mixed in. After a few laps on Jab, the differences offered by BTI bring a welcome variety to the riding on Mt. Ashland.



Widely variable, narrow trail tread with steeper grades and unavoidable obstacles of 15in/38cm tall or less. Obstacles may include unavoidable bridges 24in/61cm wide or less, large rocks, gravel, difficult root sections, and more. Ideal for advanced-level riders.
