This jagged, granite-walled mountain towers 11,000 feet over El Chaltén in Southern Patagonia. Mount Fitz Roy, which typically stands obscured in a haze of clouds, was originally named "Chaltén," meaning "smoking mountain" in the ancient Tehuelche tribe's dialect. Today, its title commemorates Sir. Robert FitzRoy, the sailor who guided Charles Darwin into South America aboard the HMS Beagle.

Visitors find the mountain striking as it's the highest mountain peak in Glacier National Park. But they also warn of the exhausting hike and harsh weather that can hinder even the most adept hikers. One TripAdvisor user explains, "Bringing your trekking shoes is a good idea, and be aware that the weather is tricky."

From El Chaltén, visitors can traverse Mount Fitz Roy's challenging series of trails on foot. Park entrance is free, while a trip to the visitor's center (open every day from 8 a.m. to 8 p.m.) will help you get oriented. Travelers suggest booking a hiking excursion with Fitz Roy Expediciones, a reliable trekking service that equips travelers with experienced mountain guides.
