Off the Beaten Path Attractions in Nigeria

I've been to a few caves before, some that human ancestors inhabited two million years ago, but the caves in Olumo rock blew me away. Historically, it's similar to Lamogi Hills in Gulu, which locals used as a base to fight British colonialists, and the locals were only defeated after the British poisoned their drinking water. In Olumo rock, locals found a refuge against enemy attacks, but they went a step further and built mud walls to create rooms within the caves, thus turning the caves into homes. To this day, caretaker families live in these caves, and some chambers are still used for ritual worship, which makes it much more than just a tourist site, the kind of place I like to visit.
