Rocky Mountain National Park
Copeland Falls and Calypso Cascades are on the way.
The trail begins at the Wild Basin TH and leads to three waterfalls. Finch Lake TH and Sandbeach Lake TH are located along Wild Basin Rd and offer more backcountry options.
An early start is recommended.
The trail to Chasm Lake is consistently steep and easy to follow. Snow coverage is possible year round, but well placed cairns will keep you on track. Be prepared and start early to ensure that you are back below treeline before the typical afternoon thunderstorms arrive.
Two Trails to Mountain Summits
How to get there:
SH7, the Peak to Peak Scenic Byway, 2.6 miles north of the Long’s Peak turnoff. Turn east for the Twin Sisters TH and park near the gate.
- From I-25/I-70 to Twin Sisters Rd
- 67 miles 1 hr 30 mins
Lily Mtn TH is on the west side of SH7, 0.5 miles further north. VERY limited parking.
Two trails leading to summits with panoramic vistas in all directions. The Twin Sisters Trail is within Rocky Mountain Ntl. Park and does not allow pets or mountain bikes. Lily Mountain Trail is in the Roosevelt NF and pets on leashes are welcome.
