Zennor Aerie is a wild, remote granite sea cliff situated along the rugged coastline between Bosigran and Zennor. The rock character is world-class, rough granite featuring steep vertical walls, immaculate jam cracks, and bold arêtes high above the Atlantic. Facing northwest, the cliff stays shaded until late afternoon, drying quickly once exposed to sun and ocean winds. The climbing caters to experienced trad climbers, offering sustained, atmospheric routes from VS to hard E-grades like Zennor Wall. The approach involves a thirty-minute walk along the coastal path from Zennor village followed by an abseil descent. Remote location, loose upper flakes, and tidal cut-offs require thorough planning.
