DH wants to walk in the mountains. DS (11) wants a beach. DD (17) wants it to be hot. They all want activities, eg windsurfing, canoeing etc. We've done villas before, but beach would be OK if there wasn't a pool. I don't want to be in the middle of nowhere, so walkable to a town/village would be nice. Would ideally drive, but it is really too far to South of France, northern Italy. Thinking maybe flying to Mallorca (northern part) or Croatia. Any suggestions welcome!
