Need to Know

Visit the Ridgway Wrench (no affiliation) in Ridgway for a copy of the latest map of the trails. Ridgway Adventure Sports also has Ridgway Area Trails (RAT) maps as well as a full service bike shop to meet all your pre or post ride needs.


The RAT system is currently a work in progress, continually evolving with ongoing construction of new trails.

In the spring of 2013, after eight years of administrative review by BLM and constant advocacy from COPMOBA/RAT, BLM issued its final Environmental Analysis and Travel Management Plan for the RAT trail network. Construction began almost immediately and, to date, volunteers and paid professionals have constructed about seven miles of rockin' new singletrack.

To start, this ride takes you up the main entrance trail; The Big Cheese. Take this trail all the way up past Speedy Gonzales and Exterminator to an intersection with Rattus Maximus, Rat Trap, and Ratical. Turn right, then right again on Speedy Gonzales. Take this trail for a short distance and then stay left on Splinter.

Splinter is a mostly downhill trail with some awesome views of the surrounding Big Blue Wilderness and Courthouse Mountain. At its end, turn right onto Speedy Gonzales which will take you back up to the "Four Corners" intersection. Turn right here again and head down Ratical.

Ratical is an easy and flowing singletrack that has some really fun undulations. Let 'er rip on this trail but don't blow past the intersection with The Plagueround. Turn right here and enter this aptly named playground. As one of the few trails that exits the trees, this trail does get hot. However, it's very easy, fun, and is great for wide open speed. Stay right when you hit the next junction to eventually reach the newest addition to this trail system.

This new trail brings you across a bridge and up a beautifully built switchback trail. While the dirt can be loose, the going is never too steep, so you should have great traction. At this trail's top, check out the views of the surrounding San Juan mountains as well as the Big Blue's. From here, the trail descends rapidly in, around, and through a creek drainage.

From this drainage, you'll be back on the bridge and onto The Plagueround. Stay right here again and head up Double Crosser. At the end of Double Crosser, turn left onto Rattus Maximus, shortly thereafter turn right onto Rat Trap. Ride the switchbacks and whoopdeedoos on Rat Trap; this trail is super fun!

From the bottom of Rat Trap, stay right onto Rattus Maximus Spur. This trail brings you to the road, which you should turn right onto. At the road, dive right onto The Maze, the last trail of your journey. From the end of The Maze, stay left to hit the parking lot you started in.

This was a really fun track. The initial switchback climbs are a beast but after that it was a blast. 8mi — 1h 15m

Though not characteristic of the whole system, there are a few fun features mixed in! Hoping more are created amongst the highly flowy system!
