Jackrabbit and Grindstone Rim Loop Map

Berms in the desert?! Yes, you'll find sections of beautiful machine-built flow trail on this desert mountain bike loop—and so much more!


The Jackrabbit Loop is the best beginner-friendly loop through what's referred to as either the "Jackrabbit Trails" or the "Logandale Trails," depending on who you ask. The ride begins by climbing the Warmup Loop trail, then connects to the core Jackrabbit Loop.

The vast majority of this ride is smooth, flowy, and largely non-technical. The singletrack undulates along desert ridges, dropping steeply into the bottom of some washes and rocketing back up the other side. The swoop and flow of this route are so superb that even advanced-level mountain bikers will have a fun time on Jackrabbit.

The swoopy machine-built sections are interspersed throughout this loop. These trails quite obviously began life as old-school renegade singletrack and have since been updated and improved with some sections of modern trail building. Even though the machine-built sections aren't continuous, some of the classic stretches of singletrack in between are absolutely fantastic in their own right, especially one short section where the trail passes through a miniature slot canyon!

The ride shown here is a slightly more advanced version of the Jackrabbit Loop that also incorporates Grindstone Rim into the loop. Grindstone Rim is a shockingly-beautiful rim edge ride, with a natural singletrack trail undulating up and down along the rim for over half a mile. From this elevated vantage point, you can spot the stunning red rock formations in Valley of Fire State Park off in the distance.

The descent off the rim is fast and furious, with some steep pitches and high-speed jumps. You'll rip through a few delightful berms and have the opportunity to hit some low tabletop jumps and a few kickers. All of the jumps can be avoided if you so desire, keeping the technicality and difficulty of this ride to "Moderate." Despite the low-level tech rating, this ride is an absolute gem that almost every mountain biker will enjoy!



Mostly stable trail tread with some variability, with unavoidable obstacles 8in/20cm tall or less. Other obstacles such as rock gullies and steep sections may exist. Ideal for lower intermediate riders.
