This is a scenic spot to look out over the reservoir. The dam itself was built in the early 1960s and required relocating the original town of Dillon, which is now sitting beneath the water. Today, the reservoir holds Denver’s largest water supply and sends it through a tunnel under the Continental Divide. Surrounded by mountain towns, Dillon Reservoir is a popular locale for boating, fishing, and summer concerts at the lakeside amphitheater.

Loveland Pass from Keystone is a fantastic high-altitude road biking challenge on US Highway 6, taking you over the Continental Divide. Starting around 9,200 feet at Keystone, you'll ascend approximately 8.5 to 11.5 miles, gaining about 2,600 to 3,000 feet to reach the 11,990-foot summit, with a steady average gradient typically in the 5.4-5.9% range. As you climb, you'll pass the Arapahoe Basin ski area and gradually transition into beautiful alpine meadows and forests before the final switchbacks above treeline offer dramatic views down to I-70 and expansive mountain vistas from the top of the pass. Be prepared for the significant altitude and potentially rapid weather changes at this elevation.

From the Dillion Reservoir Recpath there are great views of the south end of the Dillion Reservoir. The edge of the water is only a few feet away, and with the occasional tree obstructing the view, it is overall a great way to see the reservoir.
