Reserve your spot on the Trekking on Cerro Arenales in Vallecitos, Mendoza today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Acclimate before you go
Spend a day in Mendoza (700–900 m) and drink extra water—altitude effects increase above valley floor and on the climb.
Sun and wind protection
Bring a brimmed hat, sunscreen and windproof layer; UV intensifies and winds can make summit stops cold.
Footwear and footing
Sturdy hiking boots with good tread are recommended—the route includes loose scree and steeper switchbacks.
Pace the ascent
Hike conservatively on the ascent, using short, regular breaks to limit fatigue and monitor breathing.
Water reservoir or 2L water bottles
Staying hydrated is critical at altitude; guides provide water but carry your own supply for the climb.
Sturdy hiking boots
Support and traction on dirt, rock and scree reduce risk of slips on steeper sections.
Light insulated jacket and wind shell
Summit exposure and afternoon winds make a warm, windproof layer essential even in mild seasons.
