This area is very nice. From there, you could dive from Hyere to Cavalaire to golden islands (iles d'or).
There are a lot of nice wrecks, and a marine preservation area in Port Cros, with a lot of huge Groupers (Mérous). Unfortunately, most of the best wrecks are a bit deep for you (40m+, deco dives).
You can find a lot on information on
scubadata, but in french.
