A piece of the Congo's Ituri Forest inside Uganda, with boiling hot springs, lowland forest birds found nowhere else in East Africa, and the Semliki river valley.
Semuliki National Park protects about 220 km² of lowland tropical forest in Bundibugyo district, on the western side of the Rwenzori and on the floor of the Albertine Rift. It is the eastern tip of the vast Ituri Forest of the DR Congo, separated from it only by the Semliki River. Because of that link, many of its animals and plants are central African species found almost nowhere else in East Africa.

Semuliki's best-known sight is a pair of hot springs set in the forest. The "male" spring, Bitente, bubbles in an open swamp. The "female" spring, Nyasimbi, throws a jet of boiling water up to two metres high, and guides boil eggs and plantain in its pool. A boardwalk trail through the forest reaches both, and local Bwamba traditions around them are explained on the way.
Semuliki is one of Africa's top birding sites. It has about 440 recorded species, including roughly 35 Guinea-Congo forest species found nowhere else in East Africa: Nkulengu rail, several hornbills including the black-wattled and white-crested, Congo serpent eagle, Sassi's olive greenbul and the lyre-tailed honeyguide. Dedicated birders often spend two or three days on the Kirumia trail. See birding safaris.
Nine primate species live here, including chimpanzees, De Brazza's monkeys and red-tailed monkeys. Forest elephants, forest buffalo, the water chevrotain and about 300 butterfly species are also present. Semuliki is not a big-game park, since visibility in lowland forest is limited, but it is intensely rich.
Semuliki is about 1–1½ hours from Fort Portal on a tarmac road over the Rwenzori foothills, with superb views of the Rift. It pairs naturally with Kibale. Allow 7–8 hours from Entebbe.
Semuliki is best visited as part of a western Uganda circuit. Combine it with Kibale for chimps, the Fort Portal crater lakes, the Rwenzori for hiking, and Queen Elizabeth for lions and the Kazinga Channel. A 7–10 day trip can cover them all. For birders, a longer route adds Bwindi, Mgahinga and Mabamba. See tailor-made safaris.
Semuliki was declared a forest reserve in 1932 and became a national park in 1993. It is one of the few lowland tropical forests in East Africa to have survived the last Ice Age. It protects the easternmost part of the Congo basin's Ituri Forest, and its plants and animals reflect that link. Researchers value it as a place where East and Central African species overlap.
A trail of about 30 minutes through the forest leads to the "male" spring, Bitente, a steaming pool about 12 m wide in an open swamp. Another 15 minutes brings you to the "female" spring, Nyasimbi, where boiling water and steam jet up to about 2 m. The water is about 100 °C, and your guide will cook eggs or matooke in it. Local Bwamba people traditionally regarded the springs as sacred, linked to ancestral spirits, and brought offerings to them. The forest around the springs is excellent for birds and monkeys.
East of the park, the Toro-Semliki Wildlife Reserve (about 542 km²) covers savannah, woodland and swamp running down to Lake Albert. It is one of Uganda's oldest protected areas, set aside in 1926. It has Uganda kob, buffalo, waterbuck, elephants and leopards, and a boat trip on Lake Albert gives a chance of the shoebill. The Semliki Chimpanzee project studies savannah-dwelling chimps here. It makes a good add-on to a Semuliki visit.
A Batwa community lives near the park at Ntandi. Like the Batwa of Bwindi and Mgahinga, they were forest hunter-gatherers whose way of life changed when the forest became protected. Community visits show traditional skills, dance and music, and the fees support the community. See the Batwa of Uganda.
It fits naturally into a birding safari. See our 13-day birding and gorilla safari.
Accommodation near Semuliki is limited, mostly UWA bandas and a few simple lodges near Sempaya and Bundibugyo. A safari lodge in the Toro-Semliki reserve offers a more comfortable stay. Many visitors stay in Fort Portal or at the crater lakes and visit Semuliki as a day trip.
Semuliki is hot and humid, and it rains a lot. Drier months (December–February and June–August) make forest trails easier. For birders, the rainy months are breeding season, when many species are most active.
Serious birders plan 2–3 days here to target Guinea-Congo species that are almost impossible to see elsewhere in East Africa: Nkulengu rail, white-crested, black-wattled, black-casqued and piping hornbills, the Congo serpent eagle, red-billed dwarf hornbill, yellow-throated cuckoo, orange-cheeked waxbill, and many greenbuls and flycatchers. A specialist bird guide with knowledge of the calls is essential. See birding safaris and top birding destinations in Uganda.
Semuliki is reached from Fort Portal on a paved road that climbs over the northern shoulder of the Rwenzori, then drops steeply to the Rift Valley floor, with superb views over the Semliki valley and into the DR Congo. The drive takes 1–1½ hours to the Sempaya gate. From Kampala, allow 5–6 hours to Fort Portal plus the extra drive, so most visitors come from Kibale or the crater lakes.
Nine primate species live here, including chimpanzees, olive baboons, black-and-white colobus, red-tailed monkeys, grey-cheeked mangabeys, vervets, blue monkeys, De Brazza's monkeys and Dent's mona monkeys, along with nocturnal pottos and bushbabies. Other mammals include forest elephants and forest buffalo (smaller forest-adapted forms), leopards, hippos, the water chevrotain, pygmy antelope and several Central African flying squirrels. Many are shy, and night walks give the best chances of the nocturnal species.
UWA charges daily park entry, with separate fees for guided walks to the hot springs, forest trails and birding. On our tours, the fees for listed activities are included.
The Sempaya hot springs and exceptional Congo-basin birding, with many species found nowhere else in East Africa.
About 55–60 km, roughly 1–1½ hours by road.
The Kirumia trail for birding and deep forest, and the Sempaya trail for the hot springs.
A day trip from Fort Portal works for the hot springs. Birders should plan 2–3 days.
It is possible but rushed. A night between them lets you enjoy the hot springs and a forest walk without hurrying.
Yes, including Kitagata near Queen Elizabeth and Kanangorok in Kidepo, but Sempaya is the best known and easiest to visit.
Around 100 °C at the female spring, hot enough to boil eggs.
Chimps live in the forest but are not habituated for trekking. Toro-Semliki has a research project with savannah chimps.
Yes, for the hot springs, the forest and the Rift Valley scenery on the drive. It combines easily with Kibale.
Light, long-sleeved clothing and trousers against insects, walking shoes, a rain jacket, and plenty of repellent. It is hot and humid.
