Park the jeeps on the bend near the slipway. Don't worry, Gozitan driving is far worse.
Swim out following the direction of the slipway until you hit a small submerged valley.
Follow the valley out to sea, through small ravines and rock beds. Avoid the areas
of sea grass. Octopus and Scorpion Fish in plenty at this site.
If you keep going out to sea, after 20mins you will find steep drop-off from 15m down to 35m. In the cliff face you will find a very large empty cave, but your navigation, air reserves and stamina must be up to it! Better to go by boat.
