This is a short, easy trail that has spectacular views of the mountains of the Tenmile Range and the Continental Divide. The Old Dillon Reservoir was built in the 1930’s to supply water to the original town of Dillon, which is now covered by the new Dillon Reservoir. Water is supplied to the old reservoir via a diversion ditch from Salt Lick Creek, north of I-70. The Old Dillon Reservoir offers great fishing during the summer.
