For wild Galapagos tortoises, there is basically no hibernation.

Because Galapagos tortoises live in Areas with tall vegetation, such as Galapagos cacti, arid environments where prickly pears grow. Because Galapagos tortoises are resistant to cooler climates and cloudy climates, they are better adapted to high altitudes. Galapagos tortoises migrate seasonally from grasslands to areas up to 600 meters above sea level during the rainy and dry seasons. Galapagos tortoises are warm-blooded animals, so they need to absorb the heat of the sun after dawn, and spend about 1-2 hours a day in the sun.
