Jilly learns to cave dive!!!
|
So Jilly is about to join the big boys and is doing her cave diving course in Mexico… somewhere in the region of Cancun and Playa Del Carma to be precise. Renowned for it’s underwater cave systems and centoes, this is the Mecca of all cave divers. Basically the rock is kind of porus, think of a giant sponge, full of holes big enough for a person to swim through. Allow this giant sponge to gradually fill with water, and you have the cave systems of this area. Fantastic caves link up together accessible via inland pools known as cenotes. Here the land has dropped into the cave system and created a pool along the sides of which are entrances to the caves themselves. Because they were previously dry land, you even get trees under the water that have now been submerged. And in one of the caves you can see the remains of ancient civilisation, where residents way way back in prehistoric times have had campfires, the remains of which can still be seen during your dive. Jilly is keeping a diary of her time in Mexico, in particular her cave diving course, so you can follow her progress here. |
