Visit Pico Cão Grande

Neon sulphur pools, salt flats 125 m below sea level and the Erta Ale lava lake — the hottest inhabited place on Earth.

Otherworldly landscape of limestone chimneys.

Young fissure volcano between spreading tectonic rifts.

Monasteries atop soaring rock pillars.

Mineral springs that have petrified into white waterfalls of stone above the Oaxaca valleys, with cliff-edge pools you can swim in.

Rhyolite mountains streaked orange, green and pink, with a natural hot river to soak in after the walk — the start of the Laugavegur trail.

Climb 740 steps up the El Penol monolith for views over a maze of turquoise reservoir lakes.

The world’s most perfectly symmetrical volcanic cone, still active, rising 2,463 metres above Legazpi.
