Spies, Lies, and Naked Thighs commands attention on the sun-drenched face of Mota Wall in El Potrero Chico, one of Northern Mexico's premier climbing destinations. This 90-foot sport route invites climbers to test their mettle on a clean, vertical wall peppered with bolts that promise a straightforward yet challenging ascension. The climb launches smoothly onto a pristine rock surface, demanding precise footwork and controlled movement before reaching a subtle ledge that offers a brief respite.

The route’s core challenge emerges along a small crack situated just to the right of the fifth bolt. Opting to climb this crack reduces the difficulty noticeably, making the difference between a tough 5.12a and a slightly more accessible climb by a couple of grade steps. This choice opens the door for climbers eager to engage with natural features instead of purely relying on face holds, providing a nuanced balance between technical skill and raw endurance.

Protection is well established with nine bolts leading safely to anchors above a secondary ledge, where climbers can regroup and prepare for the final moves. The rock here is solid and offers reliable placements, making protection trustworthy even as the route demands consistent effort throughout. Climbers report a distinct sense of flow along the face, with the occasional challenge of maintaining grip and focus, especially under the glare of the Northern Mexican sun.

Mota Wall sits within the rugged expanse of El Potrero Chico, a climbing haven known for its limestone cliffs that tower over the desert landscape. The area is characterized by dry, clear air and sweeping views of distant ridgelines, creating a backdrop that both humbles and energizes. Approach trails are well marked but can become hot during midday, so early starts and hydration are essential.

For those tackling Spies, Lies, and Naked Thighs, solid climbing shoes with good edging capability and chalk to manage sweat will improve hold security. Given the sport climb’s brief length but technical demands, pacing yourself and scouting the crack option early on can lead to a smoother ascent. Fall protection is reliable, but the route's exposure requires climbers to be comfortable with confident clipping and seam navigation.

Whether you’re sharpening your 5.12 skills or seeking a route that blends face climbing with crack technique, this climb offers an unusual and rewarding challenge. Prepare for the dryness of the desert, early morning shadows along the face, and the satisfying pull of each well-placed bolt as you ascend. It’s an invigorating piece of El Potrero Chico’s climbing mosaic, with plenty to teach and a route to respect.
