Downstairs, the vibe shifts. The basement used to hold the pumping machinery, and now it houses the Dungeon—a low-ceilinged bouldering cave with moody lighting. It’s perfect for rainy afternoons when you want to pretend you’re a goblin. The walls here are steep and overhanging, designed to humble even the cockiest climber.
I once spent an hour trying to solve a single orange problem. I failed. But the guy next to me—who looked like he’d crawled out of a Tolkien novel—sprinted up it in three moves. He just nodded at me and muttered, “Footwork.” Then he vanished. I still think about him.
The Castle also runs courses for absolute beginners, so don’t let the aesthetic intimidate you. They even have kids’ parties, which means on weekends you’ll share the space with tiny humans in hard hats who have zero fear. Humbling, right?
Green Lanes itself: a bonus adventure
After you’ve wrecked your forearms, stumble out onto Green Lanes. This part of London is a chaotic, beautiful mix of Turkish grocers, Greek bakeries, and shops selling mysterious vinyl records. Pop into Pamir for a kebab that will restore your soul, or grab a borek from the bakery next door. One bite and you’ll forget about the calluses forming on your hands.

My post-climbing ritual is simple: sit on a bench, eat a spinach-and-cheese pastry, and watch the neighbourhood swirl. The Castle is a community anchor here—locals treat it like a third place, not a gym. You’ll see climbers chatting with dog walkers, kids chasing pigeons near the entrance, and someone calmly reading a climbing guidebook in the café. It all feels lived-in.
