Swimming activities in Nigeria
The new favourite with fashionable Lagosians is Eleko Beach, a big 60km trip east of the city. You can rent a beach hut for the day here, and get someone to make a barbeque for you. There's also a small market selling interesting art. You'll need to hire a drop taxi to get there.
You'll need to travel slightly outside Lagos to reach the best beaches. Tarkwa Beach is popular, as there's no undertow and it's safe for swimming. There are sun lounges and umbrellas, and a few stalls selling suya and chop. It's accessible by launch from along Walter Carrington Crescent in VI. The price is negotiable. Make arrangements to be picked back up in the afternoon.
