Spending the night at Acatenango base camp is one of Guatemala's most stunning experiences — you wake up watching Volcán de Fuego shooting lava 10 km away. But that same night can drop to −5°C with freezing wind. Without an adequate sleeping bag, it'll be the longest and coldest night of your life.
In this guide we compare the 5 best sleeping bags for camping in Guatemala, specifically chosen for the nighttime temperatures of Guatemalan volcanoes.
What Temperature Rating Do I Need for Guatemala?
| Destination | Altitude | Night temp. | Recommended rating |
|---|---|---|---|
| Acatenango / Tajumulco | 3,500–4,200 m | 23°F to 41°F | 20°F / −7°C or better |
| San Pedro / Santa María | 2,500–3,000 m | 41°F to 54°F | 30°F / −1°C |
