My favourite place in my city is Lekki Conservation Centre, Lagos.
It is one of the few places where you can step away from the noise of the city and enjoy nature. The canopy walkway gives you an amazing view of the forest, and the peaceful environment makes it a great place to relax, take photos, and spend time with family or friends.
If you're visiting Lagos for the first time, this is one place I believe you should add to your list. Go early in the day, wear comfortable shoes, carry water, and don't forget your camera. The experience is worth it.
