Considering the Coral Beach in Alicante?
A VT member wrote the following comment about visiting Alicante:
Isla de Tabarca by Christina1881
Tabarca is a little island outside of Santa Pola, Alicante, which obviously is a tourist-island more than anything, but even with the island full of turists (like me and the friends with whom I went) the island is magical and still seems "untouched" in some unexplainable way.
To get to Tabarca it is possible to sail from Alicante or from Santa Pola. We sailed from Santa Pola which is a trip of about 25 minutes, and about 12 Euro (return trip). There are boats each hour - only be aware that the last one leaves Tabarca around 18-30-19h in the afternoon.
Tabarca is famous for its corrals and it is a perfect spot for diving, and also have a beautiful sandy beach for swimming!
