Rito Alto four pass loop

While the tour data suggests a jogging duration of approximately 5 hours, the Rito Alto four pass loop is a challenging 23-24 mile route with significant elevation changes (around 6,000 feet). For most, it's more akin to a fast-paced hike or power-hike, especially on steep and technical sections. Plan for a full day, or even an overnight trip, depending on your fitness and pace.

No, this loop is classified as strenuous and a 'hard run,' demanding very good fitness, sure-footedness, and alpine experience. It's more suitable for experienced trail runners or hikers due to its technical terrain, high altitude, and significant vertical gain.

The loop features about 6 miles of Forest Service Road (County Road 160), which is wider and shared with ATVs, and 18 miles of singletrack trail. Expect steep ascents and descents, switchbacks, and sections with loose rock and dust. A significant portion is at or above treeline, exposing you to varying surface conditions and potential route-finding challenges, particularly in the headwaters of Rito Alto Creek.

The loop is renowned for breathtaking views of the Sangre de Cristo Mountains. You'll traverse four distinct mountain passes, including Hermit Pass (the highest point), and encounter stunning alpine lakes like Hermit Lake, Lake San Isabella, and Venable Lakes. Other highlights include impressive cirques, views of Eureka Mountain, and the beautiful Venable Falls.

The best time to visit is typically late summer and early fall. During these seasons, you might witness aspens in autumnal colors or fields of wildflowers. Water sources are generally available, even in late summer. However, be prepared for cold nights, potentially dropping into the 20s Fahrenheit, and significant exposure to wind and sun due to long stretches above treeline.

Yes, dogs are generally allowed on trails within the Sangre de Cristo Wilderness. However, always ensure your dog is under control, preferably on a leash, and practice Leave No Trace principles by packing out all waste. Be mindful of the challenging terrain and high altitude for your pet's safety.

The Rito Alto four pass loop is located within the Sangre de Cristo Wilderness. While there are typically no entrance fees for the wilderness area itself, it's always wise to check with the local Forest Service office for any specific permits required for overnight stays or group sizes, especially during peak seasons. Parking at trailheads may also have specific regulations or fees.

The loop typically starts from the vicinity of Forest Service Road (County Road 160). While specific trailhead parking details can vary, access usually involves this road. It's advisable to research current parking availability and regulations before your trip, as conditions can change.

Yes, water sources such as creeks and alpine lakes (like Hermit Lake, Lake San Isabella, and Venable Lakes) are generally available along the route, even in late summer. However, it is crucial to carry a water filter or purification tablets, as all natural water sources should be treated before consumption.

Yes, the route incorporates sections of several other trails. You will find yourself on parts of Hermit Lake Road, Venable Trail, the Rainbow Trail (FS1336), North Fork Crestone Trail, Rito Alto Trail, and even smaller segments like Venable Lake Spur and San Isabel Lake Trail.

Given the strenuous nature, high altitude, and exposure, you should bring sturdy, well-broken-in shoes, appropriate layers for varying temperatures (nights can be cold), and sun protection (hat, sunglasses, sunscreen). A water filter, sufficient food, navigation tools (map, compass, or GPS), and emergency supplies are also essential. Be prepared for potential altitude sickness and carry necessary medications.
