The best time to visit Democratic republic of Congo shifts from south to east to north, depending on rainfall and wildlife, safari activities. You can find somewhere for a beach holiday year-round, but most people go for the Congo gorilla trekking & Nyiragongo volcano hike. In Virunga National Park, the winter dry season falls between May and October when game viewing is at its best, but to gorilla trekking, you’ll need to travel between June and early September. Gorilla trekking in Uganda and Rwanda is year-round, but Jan-Feb and June-Sept are much cooler months.
Nyiragongo volcanoes can be visited all year round but keep in mind there is unpredictable weather changes such as regular rains during certain months of the year because Nyiragongo is in the middle of equatorial rain forests. Like from March to May and as well as November tends to be a rainy season.
The dry season begins in June to October and also December. So during the dry seasons the forest are always clear giving you a chance to enjoy and take photographs of the stunning landscape views of the greater Virunga mountains national park.
Nyiragongo Hike & Gorilla trekking in Congo is a year-round activity but Nyiragongo hike will be appreciative during the drier and cooler months of January and February and again from June to September.
