One Two Dive

One Two Dive, also known as 12dive, runs from inside the GF Isabel Hotel in Costa Adeje under a managing director with a marine-biology background, a detail that shows up in the centre's own site through dedicated marine-life video content rather than sitting as a background credential. That ecological framing is backed by a PADI Green Star Dive Center award for conservation, on top of the more standard PADI 5 Star IDC status. Day to day, the centre leans on small groups and a genuinely personalised approach, with a VIP option for divers who want a one-to-one instructor rather than a shared boat trip, and free pickup covers a wide stretch of the south coast from Los Cristianos through Las Américas and Adeje to Golf del Sur. The course ladder runs from PADI Bubblemaker for children as young as eight through the full recreational range and into Divemaster, alongside half-day snorkelling tours by boat or from the beach for anyone not ready to dive.

470 reviews at a full 5.0 on Google is among the strongest volumes in the area, and individual activity sub-ratings on TripAdvisor sit consistently in the 4.7 to 4.9 range. Recent feedback repeatedly praises fast, helpful responses before arrival, with one visitor describing an email query answered the same day and a booking sorted quickly once on the island. Instructors come up by name for tailoring dives to what a group can actually handle, and several reviewers call it simply the best dive school they have used in the Canaries. A longer-standing review from a spontaneous Advanced Open Water booking describes a friendly, welcoming team, suggesting the pattern has held over several years rather than being a recent shift.
