At the halfway point of the 2026 field season, the Trails Preservation Alliance Trail Crew has completed nine of 18 scheduled hitches, partnering with the U.S. Forest Service, Bureau of Land Management, state agencies, local clubs, and volunteers across Colorado and eastern Utah to improve motorized trail systems.

The Red Cone Trail is one of Colorado's most iconic high-alpine four-wheel-drive routes, connecting the South Platte and Dillon Ranger Districts while offering spectacular views and a challenging one-way descent. With thousands of visitors each season, maintaining accurate trail information and durable infrastructure is essential to protecting the surrounding environment and ensuring a safe experience for all users.

China Wall is a short, looping trail system that offers motorized users an option for difficult terrain that challenges any 4×4 vehicle. There are two separate entrances to the seasonally managed loop, and one entrance is along an easy stretch of dirt road. In past seasons, this allowed vehicles not equipped to run the full trail access to some difficult sections. Several recoveries and vehicle breakdowns resulted from this issue in the past.

The Holy Cross Trail is a Jeep Badge of Honor Trail and one of the most popular, true destination trails in Colorado. One of the unique features of the trail and one of the hardest obstacles is the French Creek crossing. A high mountain creek flows across the trail, making it wet and challenging to climb the slick granite boulders on the uphill side.

The Wheeler Lake Trail in Colorado is a difficult route that climbs through Alpine Basin, ending above treeline at Wheeler Lake. The trail is a destination for Colorado locals and motorized enthusiasts who visit the state in the summer. Near the end of summer 2025, the Wheeler Lake Trail near Alma, Colorado, suffered from a unique issue. A mining claim owner looking to dmakeimprovements to his property about halfway up the trail filled in several obstacles to get heavy equipment to his property. In doing so he altered the difficulty of the trail in an undesirable way which resulted in the difficulty of the trail being severly altered and made it much easier.

Tomichi Pass is an Alpine mountain pass that connects the old mining town of White Pine with Brittle Silver Basin. The Tomichi Pass area has a long and rich mining history, complete with a mining district and an old cemetery. The original route was built across steep talus slopes composed of highly erosive soil, and the pass has suffered several landslides over the years. One such slide in 2015 closed Tomichi Pass for several years before CORE first rebuilt the road by hand over the slide in 2019.

Tincup Pass is a high-elevation road in the Central Colorado Rockies that crosses the Continental Divide at over 12,000’. It was originally built to connect the mining town of St. Elmo and Tincup. In late 2024, a mud pit began to form along a section of Tincup Pass Road. By early 2025, this mud pit was large enough to swallow a full-size vehicle and had rendered that pass nearly unusable for most vehicles and machines.
