Simbi Nyaima

Simbi Nyaima is a volcanic crater holding a small, dark, alkaline lake outside Kendu Bay, a few kilometres from the shore of Lake Victoria and utterly unlike it. It has no visible inlet and no outlet, the water is soda rather than fresh, and flamingos appear on it. The name is Dholuo and means the village that sank.

The Tradition the Lake Carries

Luo oral tradition holds that a village stood where the water now is. In the account told around Kendu Bay, an old woman came to the village seeking food and shelter and was refused by the households she approached. One family took her in. She warned them to leave, and that night a violent storm broke and the village sank, leaving the crater and the water that filled it. The family that had shown hospitality survived.

That is a tradition, held and told by the community living around the lake, and it is set down here as such rather than as an explanation of the geology or as decoration on a landscape. It is also the reason the place is treated with a degree of care locally, and the reason visitors are not the only people at the crater rim.

A visitor who arrives and asks to be told the story is asking for something that belongs to the people who tell it. Ask, listen, pay the guide properly and do not press for versions that are not offered.

What the Crater Is

Simbi Nyaima is a small crater of volcanic origin, the water in it alkaline, with no known surface inlet or outlet.

Published dimensions for the lake are inconsistent and none of the figures in circulation trace back to a survey that can be checked, so none are given here. The useful description is a functional one: it is small enough to walk around the rim of in an unhurried morning, and steep-sided enough that the approach is a short climb rather than a stroll to the water’s edge.

The water level and the colour change. Alkaline crater lakes of this size respond quickly to rainfall and evaporation, and the shoreline a visitor sees will not be the shoreline in a photograph taken in a different season.

The Birds

The birds are the reason ornithologists come. Lesser flamingos turn up on the lake and it acts as a staging point for birds moving between the Rift Valley soda lakes, which is a long way east of here. Flamingo numbers on any soda lake are famously unpredictable, and at a lake this small they are more unpredictable still, so a flamingo flock is a bonus rather than a plan.

Alongside them the crater regularly holds little grebe, little egret, Egyptian goose and a range of other waterbirds, and the nearby Odango wetland, a short distance from the crater, adds habitat of a different kind and is usually treated as part of the same birding stop.

What this means in practice is that Simbi works as a short, specific birding detour rather than as a destination, and it pairs naturally with the lakeshore. Birdwatching in Kenya sets out how the western sites fit the national circuit.

Protection, and the Awkward Question of Fees

Lake Simbi has long been gazetted as Lake Simbi National Sanctuary, managed by the Kenya Wildlife Service, and it is still widely described that way. The current position is less clear than that description suggests, and it is worth being straight about it.

The wildlife service’s own website no longer carries a working page for the sanctuary, it does not appear in the current online list of parks and reserves, and it is not among the protected areas named on the Kenya Wildlife Service conservation fee schedule, which was checked on 21 September 2026. That means no official admission figure for this site can be quoted from a source worth relying on.

A charge is generally asked at the crater, collected locally, and guiding is paid separately. Agree both before walking in. Anyone planning around a published number should confirm directly with the Kenya Wildlife Service or with Homa Bay County rather than with a travel listing, because the figures that circulate for this lake do not trace to either.

Getting to Simbi Nyaima

The crater lies just outside Kendu Bay in Homa Bay County, on the southern side of the Winam Gulf, a short distance off the Kisumu to Homa Bay road. From Kisumu it is a straightforward drive and an easy half day, and it slots into the run south towards Mbita and the islands without a detour worth mentioning.

The final approach is a local track and the rim is reached on foot, an hour or two including a circuit of the top. Shoes with grip are worth having on a loose slope, there is no shade, and mornings are better for both the light and the heat.

Other sights in western Kenya with a comparable character and a similar way of being visited include Kit Mikayi west of Kisumu and the Crying Stone of Ilesi near Kakamega. Cultural tours in Kenya covers how visits of this kind are arranged in this part of the country, which is with a local guide rather than at a counter.
