Squaw Pass loop

While specific parking areas aren't detailed, the route is often accessed from Bergen Park or Idaho Springs. You'll want to find suitable parking in one of these towns to begin your ride.

The full loop is about 72 km (44.7 miles) with significant climbing. For a fit rider, it typically takes around 4 hours, 18 minutes to complete, but this can vary greatly depending on your pace and stops.

No, this route is generally considered difficult and requires very good fitness. It features a long, continuous climb with grades of 4-5% for most of the ride, and some sections reaching up to 10%. It's not recommended for beginners.

The best time to ride is typically during the warmer months when the roads are clear of snow. However, be prepared for rapidly changing weather conditions in the Colorado mountains, including rain or snow, even in summer. Weekends can also see high traffic, so consider riding on weekdays if possible.

The route is characterized by a relentless 4-5% grade climb, with some sections up to 10%. While largely paved, some segments may be unpaved, and descents, like on Witter Gulch Road, can have gravel on turns, requiring caution. The ride reaches high altitudes, up to 11,130 feet at Juniper Pass.

As you gain altitude, you'll pass through 'sea of green forests' and twisting roads. Around mile 13, views open up around Chief Mountain, and Juniper Pass offers distant views of Mount Evans. The landscape transitions from mountainous to high, dry mountain basins. You'll also encounter the challenging Witter Gulch Climb.

Generally, there are no specific permits or entrance fees required for road cycling on the Squaw Pass loop itself, as it primarily follows public roads within the Denver Mountain Parks system and through sections of Arapaho National Forest. However, always check for any current regulations or specific area closures before your ride.

As this is primarily a road cycling route on public roads, dogs are generally allowed in vehicles or on leash in designated areas. However, bringing a dog along for a challenging road bike ride of this nature is not practical or recommended. If you plan to stop at any specific parks or trails along the way, always check their individual dog policies.

Given the high altitude and potential for rapid weather changes, bring layers of clothing, including rain gear. Carry plenty of water, as altitude sickness can be a concern, and there may not be many resupply points. Essential bike repair tools, snacks, and sun protection are also highly recommended.

Yes, the route also passes through sections of the ADT - Colorado C - Q - Seg 4, Denver Orbital Trail, Denver Orbital Trail - Segment 2, Bear Creek Trail, and Gennessee Bike Trail, among others.

Riding the loop from east to west (e.g., starting from Bergen Park) presents a long, continuous climb. If you start in Idaho Springs, you'll have about 8 miles of a gentler climb along Chicago Creek before the road steepens significantly. Be aware that the route reaches high altitudes, so consider acclimatization and hydration, especially if you're not used to riding above 11,000 feet.
