Exit I-70 westbound directly after the Eisenhower Tunnel and park on the north side of the highway (11,140').
Coon Hill ascent routes. Red = South Ridge. Blue = Northeast Ridge. Click to enlarge.
From where you park, travel north about 0.8 miles. Coon Hill will be obvious on your left after about 0.4 miles. Gain the northeast ridge. This can be accomplished on skis or by bootpacking depending on the exact route chosen. Scramble southwest towards the ridge to summit Coon Hill.
Skins and skis are best for snow climbs in the spring. A pack with a good carry system will help during the scramble.
