Lake Bosomtwe is Ghana's only natural inland lake — a near-perfect circular crater lake about 30 km south-east of Kumasi in the Ashanti Region, roughly 60 km southwest of Kumasi's outskirts depending on your route, sitting in the Bosomtwe District around Abono, Kuntanase and Amakom. **What it is.** Bosomtwe is a meteorite-impact crater lake, formed when a large meteorite struck the Ashanti forest roughly a million years ago. The crater is about 10.5 km across, the lake itself about 8 km wide and around 45–80 metres deep depending on where you measure — one of only a handful of meteoritic crater lakes in the world, and the largest natural lake in Ghana. Because it has no outlet river, the water level is fed entirely by rainfall and groundwater, and the lake is famously slightly saline and stratified. **The name and the spirit.** "Bosomtwe" comes from the Akan *bosom* (a deity or spirit) and *twe* (to pull or drag) — "the lake of the gods," or "the spirit that pulls." The Asante believe the lake holds a powerful spirit, and traditionally fishing on Bosomtwe is done only with wooden *padua* canoes and no nets, and only on certain days, out of respect for the *bosom*. The lake is sacred to the Asantehene's tradition — Otumfuo Osei Tutu II has a strong connection to the area, and the lake features in Asante royal and spiritual history. **The people and the ring of villages.** Around the crater rim sit some 30-odd communities — Abono, Kuntanase, Amakom, Pipie, Apewu, Duase, Adwafo, Banso and others — together home to tens of thousands of people. The Bosomtwe District capital is Kuntanase. The communities are largely farming and fishing folk, growing cassava, plantain, cocoa and vegetables on the rich volcanic soil of the crater slopes. **Why people go.** Bosomtwe is one of Ghana's premier eco-tourism destinations. Visitors come for the Lake Bosomtwe Paradise Resort and the Abono side, for boat rides on the calm water, for the steep forested rim trails, and for the famous *amakye* and tilapia from the lake. The drive from Kumasi through Kuntanase and down the crater wall is one of the most scenic in Ashanti. **The science and the worry.** Because the lake is closed — no outflow — it acts as a sensitive recorder of the region's rainfall and climate. Researchers have cored its sediments to reconstruct thousands of years of West African climate history. In recent decades, though, the lake has faced real pressure: falling water levels linked to reduced rainfall and increased water extraction, deforestation on the crater slopes, and pollution from farming and settlement runoff. There have also been periodic fish kills linked to the lake's stratification turning over. A fitting Akan thought: *"Bosomtwe nnwo nsuo a, ɛyɛ asase"* — when the sacred lake holds no water, it is mere ground. The lake is both a natural wonder and a living spiritual inheritance, and its health is the health of the communities around it. If you're planning a visit from Kumasi, the Abono/Paradise Resort side is the most developed entry point — about an hour's drive — and the best time is the dry season, roughly November to March.
