Cova Tallada is undoubtedly one of the best locations for snorkelling. It can be accessed by sea, in which case it is recommended to do so in a kayak or a canoe, or it can be accessed by way of trails along El Montgó. Upon arrival, one can enter the water either from inside the cave or through the other two openings in the rock wall that lead to the sea. One encounters a turquoise seabed where the water is usually calm due to the formation of a sort of pool protected from the open sea by a rocky tongue.
The suggested route involves circling the interior of this area, keeping the wall to the right. (1)
