The Perito Moreno Glacier in El Calafate, Argentina, is a stunningly accessible natural wonder situated in Los Glaciares National Park. It's advisable to visit during Argentina’s summer months (November to early March) when the weather is most favorable. A full-day visit is recommended, allowing ample time to explore the viewpoints and take a guided boat tour or mini-trekking excursion on the glacier. The park entry fee is approximately $20 USD. Booking a tour can provide deeper insights and convenience, but the site can also be visited independently via buses from El Calafate, which is about an 80 km (50 miles) journey. Dress warmly in layers, and don’t forget your camera to capture the glacier’s dynamic ice formations.
