Chinns Lake

Located in the Arapaho National Forest near Idaho Springs, Chinns Lake is a high-elevation alpine destination known for its peaceful mountain setting, dispersed camping, fishing, and stunning lake views. Accessible via a rugged 4WD road, this hidden gem offers a true Colorado backcountry experience without venturing too far from Denver.

Location & Access

• Region: Arapaho National Forest, near St. Mary’s Glacier, west of Idaho Springs, Colorado

• Elevation: ~11,000 feet

• Distance from Denver: ~1.5 hours (50–60 miles)

Access to Chinns Lake is via Fall River Road → Rainbow Road (FR 275) → Chinns Lake Road, which is 4WD high-clearance only. The road is rocky, steep, and not suitable for low-clearance vehicles. Snow may linger into early summer, so check conditions before heading up. 

Things to Do

Hiking:

• While there’s no formal trail around the lake, you can explore social paths along the shoreline or continue higher to nearby Sherwin Lake and Slater Lake for more solitude and views.

• For those with capable vehicles, it’s a great basecamp for peak-bagging or short alpine walks.

Fishing:

• Chinns Lake is regularly stocked with trout and is a popular spot for shoreline fishing.

• A valid Colorado fishing license is required.

Camping:

• Dispersed camping is allowed around Chinns Lake and nearby lakes.

• Sites are primitive with no services, fire rings, or toilets — pack in and pack out everything.

• Fires may be restricted depending on seasonal conditions — always check fire bans before lighting a campfire.

• The area fills quickly on weekends; arrive early or visit on weekdays for better site selection.

Swimming:

• Yes, you can swim, but be prepared — the water is ice-cold year-round due to the lake’s high elevation. There are no designated swimming areas or beaches.

Wildlife Viewing & Photography:

• Early morning and evening often bring sightings of marmots, pikas, deer, and alpine birds.

• The mirror-like lake reflection against rugged peaks offers stunning photo opportunities, especially at sunrise and sunset.
