Weston, Colorado sits in the Purgatoire River valley along Highway 12, and the rock climbing here is defined by two main areas: Stonewall and North Lake South. Stonewall is the more prominent of the two, a long volcanic ridge of welded tuff that produces the kind of featured, juggy climbing you don't find everywhere in Colorado. Routes like Elephant Ears, Truck Stop Crank, Runaway Truck Ramp, and Pay Before you Pump give you a sense of the range here — the naming convention alone tells you this is a locals' crag with a sense of humor. North Lake South rounds out the options with additional sport and trad lines. With 12 active listings across both areas, Weston isn't a destination you'd fly across the country for on climbing alone, but if you're road-tripping the Highway of Legends corridor or based in Trinidad (about 20 miles east), it's a legitimate half-day or full-day stop with enough variety to keep intermediate climbers busy. The rock quality at Stonewall is generally solid, and the setting — open ridge with views down into the valley — is worth the drive regardless.
The named routes in the Weston area, including lines like Mini Thins, Ronin's Revenge, and El Segundo, skew toward intermediate sport climbers. Beginners will find the approach and route-finding challenging without a local or a detailed guidebook, and there are no obvious beginner slabs here. Experienced trad climbers will find some options, but the area is predominantly sport.
Spring and fall are the most reliable seasons. Summer afternoons at elevation can bring afternoon thunderstorms, so early starts matter — aim to be on the rock by 8 or 9 a.m. and off exposed ridgelines by early afternoon. Winter is possible on warmer days since the south-facing sections of Stonewall dry quickly, but snow and ice on the approach trail can be a factor from November through March.

Access details can change, so confirm current conditions before you go through the Access Fund or local climbing coalitions. Stonewall sits along a state highway corridor and has historically had straightforward roadside access, but land ownership in this part of Las Animas County is a patchwork, and respecting private property boundaries matters for keeping access open.
A standard sport rack with 12-15 quickdraws covers most routes at Stonewall. A 60-meter rope is sufficient for the majority of lines. Bring extra water — there are no services in Weston itself, and the nearest reliable resupply is Trinidad to the east or Aguilar to the north.
Mountain Project carries community-maintained beta for the Stonewall area and is your best free starting point. A printed guidebook specific to the Spanish Peaks and Highway 12 corridor will give you more complete route descriptions and approach notes, which matters here since some lines are not obvious from the road.
