The best time for a gorilla trek in Rwanda is generally during the dry seasons, which occur from mid-December to early February and from June to September. During these months, the weather is relatively dry, and trekking conditions are more favorable. The dry weather makes the trails less muddy and slippery, facilitating more effortless movement through the dense forests.
In addition to the dry seasons, the months of December and January offer the advantage of lower tourist numbers, providing a more intimate and less crowded experience. However, it's essential to note that Rwanda's Volcanoes National Park, where gorilla trekking takes place, has a tropical climate, and rain can occur even during the dry seasons.
The wet seasons, from mid-March to mid-May and from mid-September to mid-December, bring more rainfall and can make trekking conditions more challenging due to muddy and slippery trails. However, some travelers still choose to visit during the wet season, as the landscape is lush and vibrant, and the gorilla families may be found at lower elevations.
Ultimately, the choice of the best time depends on individual preferences, tolerance for weather conditions, and the type of experience you seek, whether it's fewer tourists, lush landscapes, or drier trekking conditions.
