The Tsereve Challenge: Everest in reverse
100+ metres is the Mount Everest of scuba diving. Far fewer people have dived that deep than have stood on top of Everest. Join the challenge: training, warm-up dives and the descent to 100+ m. Start from zero or from any point in your diving, even as a Tec Trimix 65 diver.
The final programme includes a certificate and a t-shirt. We run it in cooperation with Dive Aqaba.
