If you’re an adventurous traveller with a day to spare in Pula, Croatia, why not take to the sea? With a rented motorboat, you can chart your own course to hidden coves, island national parks, and dramatic sea caves. In this guide, we’ll highlight three top spots to visit on a one-day boating trip: the island paradise of Brijuni National Park, the cliffside cave at Kolumbarica Bay (Cape Kamenjak), and a local favourite “Seagull’s Rocks” bay near Pula. Along the way we’ll sprinkle in tips on what to pack and the best time to set sail. Get ready for an engaging, slightly off-the-beaten-path adventure on the Adriatic!

🌊 Kolumbarica Bay (Cape Kamenjak): Cliff Jumping and the Blue Cave

Zoom down to the southern tip of Istria and you’ll find Cape Kamenjak, a protected nature park famous for its rugged coastline. The highlight here for adventurers is Kolumbarica Bay, home to the sea cave of Velika Kolombarica. From your boat, you’ll see local kayakers and snorkelers flocking to this spot – and for good reason.

While there are many fascinating caves to discover in Istria, this particular one is truly special. Tucked under cliffs is a hidden grotto you can swim into, often called the Blue Cave for the way sunlight turns the water electric blue inside at midday. Climb up the rocks and dare to cliff-jump into the refreshing sea, or don a mask and fins to snorkel through the cave tunnel. Inside, you’ll be rewarded with an otherworldly glow – “the bluest light you have ever seen pierces through the millennial rocks,” creating a truly magical atmosphere. It’s one of those sights that might just leave you breathless.

Beyond the thrill of the cave itself, the entire Kamenjak peninsula is a joy to explore by boat. You can cruise along wild beaches and coves, maybe stopping at a pebbly inlet for a swim, or even pull in at the famous Safari Bar above Kolumbarica for a quirky jungle-like refreshment stop. (Hint: it’s hidden in the shrubs and wooden playground structures!) With a bit of luck, you might even spot the head of a Mediterranean monk seal – locals say one has recently returned to this area after decades.

Safety tip: When anchoring near the cave, ensure your boat is secure and not too close to the rocks, as currents and swells can gently push you around. It’s best to approach the cave by swimming or dinghy. And if cliff jumping, always check the water depth and that it’s clear of other swimmers before you leap.

🌅 Brijuni National Park: Island Paradise and Safari Adventure

Brijuni National Park is a stunning archipelago of 14 islands just a short boat ride northwest of Pula. The largest island, Veliki Brijun, is famed for its rich blend of nature and history – think dinosaur footprints, ancient Roman ruins, and even a safari park with exotic animals like zebras and an elephant roaming the grounds.

Boating around Brijuni offers crystal-clear turquoise bays and views of lush pine forests that fringe the shoreline. You can drop anchor in a designated bay or request a berth at the main island’s port (keep in mind a national park fee may apply). Once on shore, explore by foot or rent a bicycle or electric buggy to visit the sights – don’t miss the Safari Park, where Tito’s gift animals (zebras, llamas, Indian sacred cows and more) still graze in a 9-hectare area. It’s a surreal experience to go from snorkelling in serene coves to spotting an ostrich or elephant on an Adriatic island!

Practical notes:

  • Brijuni is best visited earlier in the day, before afternoon winds pick up.

  • Pack binoculars or a camera – dolphins are often spotted en route!

  • While there are restaurants and restrooms on Veliki Brijun, bring snacks and water if you plan to explore the smaller, uninhabited islets.

🪨 Seagull’s Rocks (Galebove Stijene): Hidden Cave and Local Chill Spot

Back near Pula, Galebove Stijene (Seagull’s Rocks) is a scenic rocky bay loved by locals and a great final stop on your motorboat adventure. Tucked on the western edge of the city’s Stoja neighbourhood, this spot features impressive limestone cliffs and several sea caves to discover.

The water here is a palette of emerald and deep blue, exceptionally clear and perfect for snorkelling. Anchor in the shallow bay and you can swim right up to a cave entrance at the base of the cliffs. One cave even has an opening in the ceiling, letting sunbeams shine in and create beautiful lighting inside. It’s a small but magical place to explore.

Galebove Stijene is basically a natural water park for thrill-seekers: cliffs range from low ledges to over 10 meters high, perfect for cliff diving into deep, clear water. Teens and adults alike gather here to jump, swim, or just chill on the flat rocks. There’s no beach or bar – just bring your own towel, drinks, and adventurous spirit.

Practical notes:

  • There are no facilities on-site – pack food, drinks, and sunscreen.

  • Afternoons here are perfect: the sun casts golden light, and the west-facing cliffs offer a spectacular sunset view.

  • It’s pet-friendly too, in case you have a furry crew member aboard!
