From the main parking area, Mouse starts with doubletrack. Head out the main road and continue in a clockwise direction. Many riders consider Mouse the most technical of the Tsali trails, but overall it is very similar to the others. There are plenty of loose rocks in places, and many fast, fun sections.
This trail is over 8 miles when using the overlook section and ~6 without it. To loop this extra section, stay right on Mouse at the intersection then follow it back around counter clockwise. The overlook is a spectacular view of the lake and surrounding mountains, and very close to the highest point of the Mouse Loop. After snapping some photos, get ready to descend the fastest part of trail back down. Take a left again and overlap the same small section of trail you used to pass through the first time. This time at the top of the climb, stay right on the Mouse again.
Following the lakes contours for another 3.5 miles will take you back to the intersection with the entrance road and the Thompson Loop
at Murphy Gap.
