This is a very pretty loop on Route 9, 4 & 9C around a high alpine lake just west of Leadville. The loop around the lake itself is 15 miles loop with 1,300' feet of climb on a quiet road. Park at any of the picnic areas or campgrounds around the lake if the lake loop is all you want to do.
Generally we park in Leadville across from the Safeway on US 24 and ride out E. Mountain View Dr. for the loop around the Lake for a 22 mile, 1,900' climb ride.
Or ride from Breckenridge, Frisco or Copper Mtn over Fremont Pass to Leadville, around the lake and back. Breck to Breck is a challenging 100 mile Century ride with almost 8,000' of climb.
