While on sailing holidays, snorkeling is probably the most obvious activity. Luckily, there are many amazing spots where you can overnight and have an amazing snorkeling experience in crystal clear turquoise Croatian sea.
Here are a few handpicked places that are rarely mentioned.
Zavratnica
(Mainland, just across the island of Rab)

Zavratnica is a small fjord-like bay just across ferry port Mišnjak on the island of Rab in North Croatia. This peaceful crystal clear bay hides the secret from the past that is more than worth a visit as offers wreck-snorkeling. Hidden in the bay is a German military ship sunken during WWII. The boat lies in shallow and clear water perfect for a family snorkeling adventure.
Wreck Michelle
(North side of Dugi Otok)

There is another wreck possible to snorkel and also this one is just as amazing as the one in Zavratnica. She is a cargo ship that sank in 2013, meaning that she is still in good condition although we can say the difference from a few years ago is obvious, so hurry up. The boat lies in some 5-6m depth, but amazingly clean and clear water offers a lot of fun and exploration also at just a meter or 2 perfect for kids.
As wrecks are mostly reserved for scuba divers, we place these 2 wrecks on our list of top snorkeling spots in Croatia.
Blue Cave on island Cres

This is not the famous Blue Cave from Biševo, but to be honest, it is much more attractive in any way. It’s not just the cave, it’s the bay, the village on the cliff and the watercolor that makes this place what it is. Any of those things alone is worth a visit, but here you have the whole package. The cave itself is big and is far from crowded like the one on Biševo. There is no entrance fee so you can swim/snorkel in free. The brave ones can also dive out of the cave as there is a small underwater opening at the end of the cave. If you dive in you will see the light which you can follow and you will come out of the cave under the cliff just a bit further from the entrance.
Cape Kamenjak
(Southernmost point of Istria)
Cape Kamenjak is a nature park located at the southernmost point of Istria, not far from Pula. The Cape itself is worth visiting and exploring. A green cape with numerous bays and coves, full of caves and passageways, some cliffs and pebbles, is a snorkeling paradise that never ends and makes you easily forget about time. If you lack adrenaline you can always climb one of the famous diving cliffs and of course, sip a beer in legendary Safari bar
Blue Lagoon near Split

Blue Lagoon is a cove between 3 islands, Drvenik Veli, Krknjaš Mali, and Krknjaš Veli. It is a beautiful sandy anchorage where your boat will be safe and turquoise, crystal clear water just invites you to go for a snorkeling adventure. Perfect place for an overnight with your boat.
Happy snorkeling! :)
