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. Courtesy of MTBProject.com

Mouse Branch and Thompson Loops are the more technical of the Tsali trails, nonetheless, these trails are equally fun and fast. There is also significantly more elevation change on Mouse Branch Loop. There are some gradual uphills that tend to be near the top of the mountains in full exposure to the sun, but the views of Lake Fontana make it worth all the sweat and work. A really great trail when combined with the Thompson Loop. Courtesy of Singletracks.com
