More ways to explore the area's outdoor wonders
You leave Arequipa before dawn, the city shrinking behind the rising shoulders of Volcán Chachani as puna grass and salt flats unfold. The bus hums along the Arequipa–Puno road; cold, thin air sharpens the views. At 4,300m the Stone Forest of Imata appears: vertical pillars and eroded volcanic rock that seem to argue with gravity, their shapes casting strict shadows across a high plain.

Acclimatize in Arequipa
Spend a day or two in Arequipa to adjust to 2,300m before ascending to 4,300–4,600m to reduce altitude effects.
Layer for rapid temperature swings
Bring a warm insulated layer plus a windproof shell — sun and cold can alternate quickly at high elevation.
Hydrate and eat salty snacks
High altitude increases dehydration; sip water frequently and carry electrolyte or salty snacks to maintain energy.
Sturdy shoes with grip
Trails through the stone forest and around the falls have loose volcanic rock and wet sections — shoes with good traction help.
Insulated jacket
Keeps core warm during cold mornings and windy summits.
fall
Sturdy hiking shoes
Provide traction on loose volcanic rock and wet riverbanks.
Sun protection (hat, sunglasses, SPF)
High-altitude UV is strong even on cool days; protect skin and eyes.
summer
Water bottle with filter or 2L capacity
Bring ample water; refills aren’t guaranteed along the route and altitude increases needs.
