Quemazon/Pipeline Loop

This loop is considered challenging for mountain biking, requiring a difficult fitness level. The climb difficulty is rated as 'Black Diamond' and the physical rating as 'Hard' on platforms like Trailforks. Expect a very steep ascent, gaining about 1,500 feet in three miles, and technical sections with volcanic tuff rock, ledges, and small drops.

The terrain is quite varied. You'll encounter packed dirt, sections of volcanic tuff rock (similar to slick rock), and rocky areas, especially on descents. While some parts offer 'flowy singletrack,' there are also ledges and small drops that make it technically engaging. The steep climb on volcanic tuff rock is a defining feature.

Riders are treated to outstanding views of Los Alamos and its surroundings, with grand vistas throughout the loop. As you ascend the mesa and traverse along canyon rims, you'll get panoramic 360-degree views, making the arduous climb very rewarding.

The best time to ride this trail is typically during the spring, summer, and fall months when the weather is favorable and the trail conditions are dry. Winter mountain biking may be possible but could involve snow and ice, making the already technical sections more challenging. Always check local weather and trail conditions before heading out.

You can typically access the loop from the Quemazon Trailhead. Specific parking information for this trailhead should be available locally, but it's the primary starting point for many riders tackling this route.

The Quemazon/Pipeline Loop is located within the Santa Fe National Forest. Generally, there are no specific permits or entrance fees required for day-use mountain biking on trails within the National Forest, but it's always a good idea to check the latest regulations from the U.S. Forest Service or local ranger district before your visit.

As part of the Santa Fe National Forest, dogs are generally allowed on trails. However, they should always be kept on a leash to protect wildlife and ensure the safety and enjoyment of all trail users. Please remember to pack out any waste.

This 7.8-mile loop offers a strategic choice: you can ride it as a strenuous climb directly from the Quemazon Trailhead, or you can opt for a less direct ascent by first climbing via Pipeline Road, which can make the overall experience different. The Quemazon Trail portion itself involves a very steep climb on volcanic tuff rock.

Yes, the route incorporates sections of several other trails. You'll spend significant time on the Quemazon Trail and Pipeline Road. It also connects to the Perimeter Trail and may briefly intersect with trails like Cave of the Winds Trail, Quemazon Nature Trail, and Satch Cowan Trail.

The primary highlights of this loop include the challenging and scenic Quemazon Trail itself, known for its steep climb and technical features. Another notable section is the Technical Perimeter, which offers rocky terrain and engaging downhill sections. The panoramic views of Los Alamos are also a major draw.
