OTB (Over The Bars) is an amazing and largely underutilized singletrack between Western States (aka Tevis Trail)
and the TRT.
The trail has amazing views, great rock formations, and is a beautifully built trail. Notice the craftsmanship of the built rock walls and other great features.
This is one of our favorites as both a climb or descent on epic singletrack loops. Although the trail doesn't include anything particularly gnarly, I rated it as difficult due to exposure (narrow trail on steep hillside).
Trail entrances are fairly obvious on both ends, but motorcycles regularly tear down the signs (since they say "No Motos." Keep your eyes peeled, and it should be easy to find.
