The Gallouneys Blockhaus - The dive on the blockhaus is quite interesting when tide coefficients are low. One mustn't forget that we are at the entrance of the Arcachon lagoon and therefore, the dive is only possible at tide slack due to the strong currents in this area. The water is often murky but will still be able to see enormous conger eels, spider crabs, rays and, for the lucky, the to rare lobster. The blockhaus are scattered on a 200 to 300m area and one can easily visit 3 to 5 of them in the same dive, due to their shallow depths (3 to 20m). Finally, an excellent map op the area can be purchased from the local diving shops; it shows the GPS ordinates, depth, directions, distances and type of each of the 17 blockhaus found on this spot.
