Basalt-organ boat dive off Dakar with gorgonians and pelagics.
Basalt-organ boat dive off Dakar with gorgonians and pelagics.
Seminol is a dramatic boat dive off Dakar's Iles de la Madeleine, built around basalt organ-like formations and long rocky bands. The site feels more like a volcanic seascape than a classic reef, with eroded promontories and gorgonian fields giving it a stark, layered look. It is an advanced, slow-look site: schools of pelagic fish move through the relief, and the rocky terrain can hold grouper, moray eel, torpedo ray, scorpionfish, crab, barracuda, trumpetfish, and other small life. The appeal is the landscape as much as the life, especially when the water is settled enough to let the plateau stand out.
