Qualify changing details
Hours, fees, access and trail conditions can change. We ask visitors to confirm them near the date of travel instead of presenting stale details as current.

Sources before superlatives.
This page records what supports the visitor guide, what remains uncertain, and who made the documentary photographs used on the site.
Last reviewed · 21 July 2026How we work
Clear about what is known—and what is not.
Label oral history
Erin-Ijesa’s founding and the discovery of Olumirin are carried in several community traditions. They should be shared as living oral histories, not collapsed into one settled archival account.
Keep photographs documentary
Real images of Erin-Ijesa lead the experience. Decorative generated artwork is used only for the social sharing card and is never passed off as a photograph of the place.
