"Big Block offers easy access to shaded limestone bouldering and sport climbs just south of Albuquerque. Its signature detached cube and reliable dry cave provide a unique experience perfect for climbers seeking technical challenges and quick approach times."
Just a short drive south of Albuquerque lies Big Block, a limestone bouldering and sport climbing destination that blends convenience with quiet adventure. The crag’s most striking feature is the massive cube detached and resting on one corner—a clear landmark that marks your arrival. The setting is refreshing for climbers who want easy access without sacrificing a touch of wilderness. The north-facing aspect ensures the climbs remain largely shaded throughout the day, a real relief under New Mexico’s often intense sun. Even when rain rolls in, the cave remains dry, offering a reliable refuge and an opportunity to keep climbing despite the weather.
The approach is straightforward and well known to locals: from I-40, head south on Highway 337 (also known as South 14) for roughly 4.5 miles. You’ll spot the block immediately to your right. From there, a short hike down and across a stream bed brings you right to the climbing zone. The terrain is friendly, perfect for a quick adventure or a day-trip to sharpen skills on compact limestone formations.
Climbing at Big Block focuses mostly on bouldering, with some approachable sport routes to mix things up. Elevation here is about 6,927 feet, lending cool mountain air that complements the shade. Climbers of varying levels will appreciate the selection of classic problems here. For those who crave steep, technical challenges, "Pegboard" (V6) and "The Baseball Problem" (V8) offer demanding sequences, while "Reachy Sidepulls?" (V9) pushes into higher commitment moves. For those leaning toward sport climbing, routes like "Block Left" (5.9) and "Blockade" (5.10a) provide solid limestone face climbing with dependable holds and moderate difficulty.
You’ll find a variety of styles in the classic climbs, including crimpy faces and powerful pinches. Notable problems like "Murray Pinch" (V10) and "Double Bump" (V10) offer serious tests for seasoned boulderers ready to push their limits. Meanwhile, easier problems such as "The V3" (V2/V3) make the area accessible for climbers warming up or dipping their toes into limestone bouldering. The atmosphere at Big Block balances laid-back and focused — a great spot to sharpen technique without the crowds or travel strain of larger areas.
Big Block’s limestone stone offers good friction but demands sharp footwork and precise body positioning. It’s an inviting arena for those who want to hone their skills or simply enjoy quick lines with minimal access hassle. The north-facing shade means cooler climbing hours best fall in mid to late morning or late afternoon, especially in the warmer months. Winter offers mild climbing weather, making this an all-season destination for local and visiting climbers alike.
Gear-wise, standard bouldering pads and a brush will cover your needs. The climbs usually stay dry even during short rains, but wet conditions can make the limestone slick, so check conditions before heading out. The approach’s stream crossing is mild but can be slick after heavy rain, so plan accordingly. While the crag is easy to reach, expect some natural obstacles underfoot when crossing the stream bed, so sturdy footwear on approach is recommended.
