With airy ridges and a knife-edge tiptoe, this 7-mile route is like an alpine fantasy come true. And if you’re a sucker for ancient mythology as well as mountain challenges, it doesn’t get any better. In Welsh, Snowdon, the highest mountain in the country, is called Yr Wyddfa: “the burial place.” According to legend, King Arthur and his knights fought their last battle on Snowdon’s slopes and were entombed there.
Begin from the Pen y Pass trailhead and follow the broad Pyg Track toward Snowdon, but take the first major fork to the right, at a stile where a fence crosses the main trail. Follow the steep track up and right, onto the black buttress overhead, then scramble up the hard black rock on solid handholds. Top out on the east end of the Crib Goch ridge, make your way along the arête, clamber over the airy Pinnacles, and cross the second knife-edge ridge of Crib y Ddysgl. The ridge broadens until you reach Snowdon’s 3,560-foot summit, which has head-spinning 360 views, but can feel a bit anticlimactic because of a tourist train that delivers the only crowds you’ll see on this route.
From the peak, drop southwest for several hundred yards, then find a faint path that cuts across the south face of Snowdon to Bwlch y Saetheau (Pass of the Arrows) where—according to legend—Arthur made his last stand. Climb on good trail across the summit of Y Lliwedd, and follow the ridge until you see a path that turns left and descends to the lake of Llyn Llydaw. There, you’ll intersect the Miner’s Track and follow it back to Pen Y Pass to close the loop.
Warning: While in nonwinter conditions this hike requires no technical gear, you need solid scrambling skills and comfort with serious exposure.
