Hidden just south of Morning Sickness and flanked by the wild, forested landscapes of British Columbia’s Cariboo, The Rats Nest offers climbers a gritty, no-frills experience in the heart of Williams Lake’s Esler region. With an elevation perched at over 3,100 feet, this compact crag rewards those willing to venture up the rugged approach gully with a mix of striking and challenging single-pitch sport routes. The scene is unpretentious and welcoming—verdant pines, rocky gullies, and the feeling of real adventure, all within striking distance from town but a world away once you find yourself at the base of these weathered faces.

The Rats Nest’s collection of eight documented lines each carries its own character, but several standouts continually draw climbers back. Holey Shit (5.9) is a crowd favorite, known for its steady movement and the kind of exposure that keeps the heart rate elevated even on moderate terrain. Those seeking technical satisfaction find plenty to chew on with Relief Man (5.8), a well-loved line that balances accessible difficulty with just enough edge to keep it interesting. For newer sport climbers, it’s a confident step up from the easier grades in the area—while those progressing toward harder sends will find a worthy challenge on Trembling Weasel (5.10c), where precise moves and solid mental focus pave the way to the top.

Arriving at The Rats Nest is part of the charm. The approach trail branches south off the main path near Morning Sickness or heads up from the north after passing Obsession Wall, weaving through pine needles and patches of rocky debris. There’s nothing fancy about the trail, but it’s navigable and direct, giving you a few minutes to shake off the world before the day’s climbing begins. While the vibe remains laid-back, the sense of isolation grows as you reach the gully—birds in the trees, wind through the branches, and the distinct quiet of northern British Columbia.

While specific route heights can vary, most lines here tend toward straightforward single-pitch affairs—perfect for honing technique or pushing your grade without worrying about complex multi-pitch logistics or elaborate rappel descents. Protection is excellent on established bolts, and anchor setups remain dependable, so lead gear is minimal and confidence is high for each clip.

Prime climbing season stretches from late spring through early fall, with the elevation helping to keep the air cool even as valley temperatures rise. Walls face a variety of aspects, so you’ll find shade or sun depending on the hour; mornings often bring dry, cool conditions ideal for tricky sequences and relaxed belays. In spring, unpredictable Pacific weather systems can bring occasional moisture, so keeping an eye on the forecast and moving quickly between squalls is smart.

The area doesn’t claim grand vistas or endless routes, but it’s this raw, practical encounter with the rock that makes The Rats Nest a must for local climbers and road-trippers alike. This is the kind of spot where you learn not just about movement and technique, but about what climbs like these add to your journey—a hard-won summit smile, laughter echoing off the walls, and the subtle thrill of earning the view back down the gully.

Whether you’re working through the classics or just looking for a solid day outside, The Rats Nest stands as a reliable entry in the Williams Lake climbing scene. Pack for rugged simplicity, bring your best attitude for the approach, and enjoy everything this hidden crag has to offer.
