St Elm & Sa Dragonera are about 56 km from Casa Fortuna about a 45 min drive.
Sa Dragonera is an uninhabited islet located just off the west coast of Mallorca It is currently a nature reserve.
We visited this October (13) unfortunately the boat trips across had pretty much finished. The crossing is from St Elm. We explored the coastline and plan to revisit the island in late spring.
