The island of Smokvica is a popular stopping off point for those heading north in to the Kornati National Park. There’s no ferry service so it’s lucky you have a yacht!
The large hill is worth a climb for the views from the top across the park.
There’s just one bay, Lojena, on the south side. It’s sheltered from all bar winds from the south.
The island is uninhabited except by a few restaurant staff in the summer. There are two restaurants which provide quay space (provided you eat at their restaurant) or it’s possible to anchor with a line ashore.
