Murallas del Infierno 2026

Murallas del Infierno is an open-water swim in Santiago del Teide, on Tenerife's west coast, set against the Los Gigantes cliffs. It takes place in November, offering two distances: a 1.5 km swim and a 6.5 km crossing for those seeking a more demanding sea challenge. The 1.5 km option follows a circular course off Los Guios Beach. The 6.5 km route begins at Masca Beach and concludes at Los Guios Beach. The event is part of the Calendario Aguas Abiertas, and wetsuits are permitted, a consideration for an Atlantic swim where conditions can be as influential as a swimmer's fitness.
