Best for expert divers, 25-64m, shore entry, mild current.
Atlantis Tunnel is a partially submerged volcanic lava tube extending from the shoreline of Lanzarote. As one of the longest known submerged volcanic tunnels, it offers a true overhead environment requiring cave certification. The site features depths ranging from 25 to 64 metres, with an average depth of 35 metres. Visibility remains consistent at 30 metres, and currents inside the tunnel are generally mild. Divers must navigate deep, overhead conditions with entanglement risks and no mid-tunnel ascent options. Shore entry requires protective footwear to avoid sharp rocks. Redundant lighting is essential for tunnel sections beyond the entrance zone. A cafe is available on-site for surface intervals.
