A swell parts around the boat and the Atlantic breathes cool onto your face as the crew runs through checks. You step off the ladder into blue that narrows into tunnels and walls — Tenerife’s volcanic underworld calling divers to explore reefs, arches and sudden drop-offs. Guided small-group dives here favor relaxed exploration: no strict time pressure, choices of successive sites, and personalized attention from local guides who read currents the way sailors read wind.
