Cruise past Mount Athos
Ouranoupolis is described as the gateway to Mount Athos, and people flock here to take boat trips past its tree-clad slopes. You’ll see huge monasteries dotted along the peninsula as your boat traces a path southwards, and it’s worth packing a set of binoculars, as you’re not allowed too close to the shore. It’s not uncommon for dolphins to follow the boats, either, so keep your eyes peeled.
