If you enjoy high speed adventure, try the jet-ski located on the beach near the rocks.  It's really a lot of fun if you have someone riding another jet-ski!  You can go around to the north side of the Coeur d'Azur.  If you are really up for a challenge, try taking the jet-ski to the east side of the village to the boat docks (you can ride along the south side of the village).  The border crossing may cause you to panic, but just don't try to over-compensate for what you see (same as the Vespa).
