Lake Victoria has numerous island and to mention the main,
The fossil beds are layers of volcanic ash produced by a succession of explosive eruptions during the earliest stages of a volcano that eventually covered an area 75 miles in diameter. The volcano is now eroded down to the frozen magma in its vent that makes up the Kisingiri hills on the mainland opposite Rusinga, and the surrounding remnants of the cone: the semicircular Rangwa mountain range, and the islands of Rusinga and neighboring Mfangano Island.
This rift valley volcano on the southern flank of the now-inactive Winam Gulf tapped much deeper in the mantle than oceanic or subduction zone volcanoes, and its lavas and explosive ash clouds thus contained much more carbonate and alkali than normal.
The island preserves everything from caterpillars and berries to apes and elephants in an unusual situation found only in a few other East African ex-volcanos, notably Menengai and Homa Mountain in western Kenya, Napak and Mount Elgon in Uganda, and the much younger Ol Doinyo Lengai in Tanzania, which created the fossil beds of Olduvai Gorge.
It is home to the Suba people. There are also many of the Luo tribe inhabiting the east side of the island. They are mostly fishermen and subsistence farmers. The people are friendly and welcoming. The languages spoken are Suba, Luo, Swahili, and English.
Most inhabitants live near the water for ease in fishing and collecting the day's water supply. The water's edge of the island is quite rocky with a few black sandy shores. Transportation consists mostly walking and of boat travel in small wooden handmade boats that sometimes have a sail. There are a few bicycles now that the government has begun to cut in a road that will circle the island.
Ndere Island is a small island (4.2 sq km) in Winam Gulf of Lake Victoria in Kenya. It was gazetted as the Ndere Island National Park in November 1986.
Ndere means "meeting place" in Dholuo. According to Luo folklore, early tribal migrants rested up near Ndere after their long journey south up the Nile River Valley. They found the lush shoreline so pleasing that they stayed. Notable fauna include African fish eagles, swifts, hippopotamus, and crocodiles (including lesser known spotted crocodile). About fifty impalas have been introduced to the island.
