Thunderkiss commands attention as it carves a demanding and dynamic path up the steep north wall of Las Estrellas Canyon, offering an intense nine-pitch adventure that feels both relentless and rewarding. The route guides you across the rock from west to east, threading through changing terrain that tests your technique and endurance through varied styles of climbing. The opening pitch immediately sets the tone: a technical 5.11b that challenges you with delicate moves low on the wall before easing slightly as you gain height. From there, the climb unfolds with shifting characters — a 5.7 slab and gully offering a breath, before the so-called 'Hash Mark' pitch at 5.10d introduces an exposed dihedral that invites confident footwork and steady hands.

Pitch four stands out as a highlight with its 5.11d grade, demanding sharp precision as you navigate right and then face a crux straight up, blending muscle and finesse. Midway through, traverse pitches make you think carefully about your line, particularly the 5.10b fifth pitch leading you up and right to a pivotal ledge. Then comes the route’s heart — a confronting 5.12a pitch where you must commit to a sharp right traverse before launching into a bold, sustained crux moving vertically.

Later pitches keep the intensity high. The seventh, rated 5.11b, is steep and dominated by large tufas, but requires caution; recent rockfall has compromised holds and bolts, so vigilance is vital. This section demands respect and sharp route reading to maintain flow and avoid hazards. The final two pitches descend in difficulty but offer little relief: a sharp 5.9 followed by a less enjoyable 5.7, both marked by sharp rock that tests your foot placement and patience.

At the summit, a panoramic vantage reveals the expanse of Las Estrellas Canyon recessed below, a fitting reward after sustained effort. The full 950-foot climb isn’t just a physical challenge but an exercise in route management, with many traverses requiring mental focus alongside technique.

Descending demands care. The rappel is essential, but the route’s layout means some rappels hang above the busy Club Mex Wall, making rockfall prevention critical. While an alternate rappel line descends more directly, it crosses over active climbing zones. Your timing and communication with other parties below will keep moves safe. This reality makes the descent as much a test of caution and patience as the ascent is of skill.

Thunderkiss has a gritty character that rewards prepared climbers. Quickdraws are your basic tool here, but the amount needed depends on your style and efficiency on the long pitches. The rock can be sharp, the protection configuration can shift over time, and the exposures will keep your focus sharp the entire climb. Ideal for those seeking a big wall experience with varied terrain and a blend of technical cruxes, Thunderkiss is not to be underestimated but offers an exhilarating line in one of northern Mexico’s premier climbing walls.
