The physical home, the spiritual home, the obvious home of North Wales bouldering, the Cromlech boulders aren't just the first place many people go for their outside bouldering fix, they're often the ONLY place people go. There are doubtless climbers out there who have climbed Rampless - an awkward sloping traverse often above rubbish left by tourists and next to parked cars - who have yet to do King of Drunks - a super classic up the hillside at the Wavelength - such is the allure and the convenience of this crag.
And it is difficult to count against such convenience. When there are more problems than seconds in the approach, it is hard to venture further afield, especially when some of those lines contain such great quality: The Ramp, Pocket Wall, Heelhook Traverse, the Cromlech Roofcrack, Diesel Power, the list goes on of amazing climbing.
Then of course comes the home of the hardcore: Jerry's Roof. While many may argue that Parisella's Cave should be the best host for those in the upper 7s and beyond, Jerry's always maintains that certain draw and contains as much history in it's handful of problems as the entire cave.
The downside is that the rock can be sharp, the tourists plenty and their mess left behind. Pick a high-season sunny day and the convenience soon disappears, just as the parking spots have too. Nevertheless, show me a North Walean boulderer who has not been to the Cromlech roadside face and i will show you a fool.
