One option is a trip out to the islands, either by hiring a RIB or taking a trip boat. Scubaman did an excellent write up recently, and we finally got round to walking round the island earlier this week. There's a restaurant where you can get lunch overlooking the anchorage.
Hi Nick H: info very much appreciated! Hired Capelli 7m RIB with 200HP Yam and toured the islands with SWMBO today. Great service and support from Dream Yachting, too. This end of the season it is very quiet and as our very first outing in the Med, really looking forward to moving out there later this year.
