Diving notes

Source: Pêches et Océan Canada -- Fisheries and Oceans Canada

On the aerial photo, you can see the wharf of Percé. On the very left side, if you follow the beach, you will find the dive center (off picture).

Behavior to have: respect the environment and the fauna.

The picture on the left shows Percé Rock and Bonaventure Island. The picture on the right shows a side view of the Percé Rock from Surprise Hill (Côte Surprise).

The dives are done from a boat (except otherwise). The water current is mild (except otherwise). Ask to local dive operators. The dives are done in sea water, watch your buoyancy. Raise the weight on your weight belt accordingly. A 7.5mm thick neoprene wet suit is mandatory. A dry suit may be more suitable depending of your comfort habits. Water temperature varies around 60°F but with underwater currents it may drop to around 48°F.

For each day of diving, you will have to pay an access fee of about 3.50$ (price in 2001). Make representation to the authorities of the SEPAQ by asking them to install a dive permit with certification card inscription valuable for a year like the system put in place at Tobermory in the georgian bay in the Great Lakes. This way it would be more practicle for divers and dive operators. Otherwise, you need to have a permit each day. Imagine the time it takes each morning for a group of 20 divers!

It is important to note that if you do your dive from the shore, a dive flag is mandatory. It is important to know that you may encounter lobsters which may have claws as large as a man’s your fingers. Watch your buoyancy otherwise you may sting yourself on urchins. Seals on their side like sometimes to play with you... Take note that in case of emergency, the cell phone can be used on most of the dive sites, please ask and test (phone someone before diving).

130-70′Rocher PercéBe CAREFULL a dangerous dive for expert only. From shore, the distance to cross is quite important by foot. Taking into account the strong currents up to 5 to 7 knots, they can drift the diver within the ferry crossing line. This is a dive that should be done under the supervision of the Club Nautique. Rock base and hole. Watch for the high tide and waves backwash. At 70′ deep, an underwater lobster tank can be visited with authorization.
240′Cap BlancFrom the shore the distance to cross is quite important, at the base of the white calcareous cliff whose summit is called Surprise Hill. At ~40’ deep the rest of shipwreck can be seen.
330′La Roche Carrée1st site while arriving on the island. The immense block of rock can be seen from the shore. In swallow waters. Many small grottos.
445′L'Anse du BilboComment from Georges Mamelonet: the site is above all doubt the most accessible for elementary divers and for fauna and flora lovers. All kinds of sea animals can be found. The site is full of caverns which make a underwater garden. Absence of current and shallow water dive make the dive absolutely marvelous.
535′La GrotteFollow the corridor to get to the cave.
