I've had the privilege of visiting Olumo rock with my parents when I was little. We had planned the trip for a very long time, thank God it finally happened. It is located in South western Nigeria, in the city of Abeokuta, Ogun state.
I've visited it like 4 times since then so I can easily give a description.
Olumo rock is 137 metres high above the sea level and 25 metres wide. That's pretty huge.
BRIEF HISTORY
According to legend, Olumo Rock was discovered by a hunter named Adagba, who utilized it as a fortification during the 19th century intertribal fighting. Before the Oyo Empire fell apart, the Egbas were a part of it. The rock also functioned as a lookout post for the locals at the time, giving them a clear view of the enemy's progress in a conflict they finally won. "Olumo" is a mixture of two words: "Olu" (God) and "Mo" (Moulded), which means "God has ended our worries and pains." In 1976, on February 3, 2006, former President of the country, Olusegun Obasanjo commissioned it as a tourist site.
It was discovered that Olumo Rock produced water that herbalists might utilize to cure ailments and sicknesses during the rainy season. However, it hasn't produced water in almost 50 years.
There's an art gallery there filled with amazing works from different artist. Tourists aren't allowed to take pictures of the art but can bask in it's beauty.
The atmosphere there is beautiful, cool breeze in harmony with the singing of the birds as well as the sound of the dry leave cracking at your feet. It's beautiful, I like to describe it as the music of the earth.
For people interested in exploring, you are allowed to walk your way to the top with proper guidance of course. People still live there, you are allowed to explore caves under the road. You'd see how the people lived and ate under the rock.
The good thing about Olumo rock is that it's easy to climb, stairs were carved into the rock for people to move easily but if you're not one for climbing, there's an elevator provided to get to the top easily.
You'd also have the privilege of seeing the shrine there. The tour guide gives an detailed story of how the shrine was made an how it was used.
The view from the top of the rock is amazing, you could almost see the whole city from up there. There's a yellow line drawn indicating were people shouldn't pass because it is dangerous and you don't want to fall.
There are alot of stories to be told about the rock. If you're ever in town, be sure to visit. It'd be worth your while
