Zminjak is a small island about a mile north of Murter. It’s uninhabited apart from the staff of the single restaurant. There’s no ferry service to the island so you need your own boat to get there!
It’s a pretty spot but you may be disturbed by the regular passage of other boats, though things quieten down in the evening. It’s well sheltered aside from winds from the west or south west.
Like most Croatian anchorages, it now has mooring buoys though there’s also a long jetty stretching our from the restaurant. You pay 200kn (2019) to moor or it’s free if you eat at the restaurant.
There’s a pebbled beach which is very easy to get to: Just walk down the jetty!
