Dakar City Tour
Some capital cities on the African continent are hit and miss, but I thought Dakar was definitely worth allocating half a day. There's plenty to see, but the points of interest are spread out, so you'll definitely need a taxi. In my opinion, the top spots are Dakar Cathedral, The Grand Mosque, Dakar Railway Station, Mosque of the Divinity, and Obelisk Square. In addition, there's some impressive street art around the university campus area.
Goree Island
A tiny island off the coast of Dakar that's easily reachable via ferry in under 20 minutes is Goree Island. This place played a major role in the Atlantic slave trade during the 15th-19th century. On the island itself, there's narrow streets lined with colonial buildings, as well as remains from past conflict. The House of the Slaves is one of the highlights, as well as various view points. The ferries operate multiple times a day, so you have flexibility with how long you want to stay for.
Lake Retba
Lake Retba, referred to as the "Pink Lake" is a great spot, but does seem to differ greatly throughout the year regarding the level of pink. It's located 30km North East of the capital and easily reachable via road. The colour of the lake is due to a combination of salina algae and high salt content. There are locals dotted around the lake that will happily take you on a short boat ride for a small fee. You will also see workers gathering the salt from the base of the lake onto small boats. It's a tough job in hot conditions for minimal pay, so I had huge admiration for the workers.
