Mountain Biking Lost Trail-twin Creeks Ridge

****   Add a review
#122 of 317 mountain bike trails in Idaho
#7,029 in the world

Except for the roads on the beginning and end of the ride, the route is singletrack. A shuttle is recommended for this ride. The Divide trail 106 has numerous short climbs and descents on its way south to the junction with Trail 109 which goes down a long steep ridge. This section of trail is a great downhill brake burner run. Watch out for the slick wooden waterbars. The ride is best ridden counterclockwise from north to south. The trail goes through an old burn (2003) so downfall may be numerous if not cleaned out recently.

    This is a great day trip trail in the Lost Trail Pass area. The downhill at the end is awsome. You ride south on the Idaho, Montana Divide and take the first left trail heading east down the ridge to Twin Creeks Campground. You can also ride farther south out the Divide trail and take the Twin Creeks trail down to Twin Creeks Campground. That is a more difficult trail with several creek crossings.
