Travel on foot (hiking) · Croatia

Hi there, Once again, I’m turning to VoyageForum to kick off my trip planning—this time, it’s Croatia! I’m treating my 29-year-old daughter to a trip where we’d love to combine hiking and snorkelling. I’m not sure if we can focus on just one region, but that’d be ideal since we’ll only have 10–15 days in August this year. Could anyone point me in the right direction for a first lead? Are transport links easy to navigate? Is it better to go with Airbnb or a hostel? Thanks in advance for your tips! Laurence from Bayonne
