Trail
Heil Valley Ranch
Nineteen miles of trail south of town; the Picture Rock trail runs from the Lyons side up to the ranch and links to Wild Turkey and Wapiti for a long loop.
The big open space south of town. Picture Rock (5.2 miles, moderate) climbs from the Lyons side and links to Wild Turkey (2.9) and Wapiti (3) for a long loop; the Ponderosa, Overland, Schoolhouse and Lichen loops sit by the main trailheads off Lefthand Canyon Drive. On-trail only, since it is elk habitat; no dogs and no e-bikes anywhere on the ranch.

Read about Heil Valley Ranch
- Lyons hikes: where dogs are allowed, and where they are not
Rabbit Mountain is the one trail area near Lyons that takes dogs, on a leash; Hall Ranch, Heil Valley Ranch and Button Rock do not. In town, Bohn Park has a ten-acre off-leash area. Each manager's rule, with distances, hours and parking from its own page.
- Trails and the river: five areas inside fifteen minutes
Two creeks, one whitewater park, and five trail areas within fifteen minutes of Main Street. Start with the river gauge: the number decides what kind of day it is.
