The Blue Cave

Famous for the iridescent blue that's reflected throughout the cave, the Blue Cave is one of Montenegro's most popular attractions.

The Blue Cave on Lustica Peninsula is one of the must-see attractions while you’re on the coast.  We visit several times a year, usually while we’re heading over to our favourite place in all of Montenegro – Dobra Luka –more on that below. We also take all our visiting friends and family out there and it never fails to impress.

The cave is the largest of many caves both above and under the water on Lustica Peninsula. We’ve spent untold hours in summer exploring the little nooks and crannies of Lustica Peninsula.  In the past we’ve found a tiny hidden beach that you can only get to by swimming through a cave. There are also underwater cave systems here than you can explore on diving trips.

It’s called the Blue Cave because the way the light hits the sandy bottom and reflects up through the water makes the whole cave look blue.

It’s very beautiful and it’s a lucky quirk because almost all of the coast here is rocky, not sandy. You can see the blue light shining out of the cave when you approach, but to really see it you’ve got to go inside and get underwater.

Don’t forget your snorkel or goggles when you come here!

The water is only about 5 metres deep and then goes much deeper further inside the cave. This part is rocky rather than sandy and if you bring your snorkel or goggles you’ll be able to see some small fish swimming about. 

The ceiling is about 9m high so there’s plenty of room for boats to come in. The tour boats will come and give you a chance to get out, have a swim, snorkel and explore before they set off again.  You can explore the cave for 10-15 minutes and then head off to the next stop.

Although there are a lot of tour boats visiting here, especially in July and August, it’s never overcrowded because you don’t need a lot of time to see the cave.

How to see the Blue Cave

You can only get to the cave by boat. Luckily there are plenty of ways to catch a boat out here to see the cave. There’s no charge to enter, it’s open to the public. Keep reading to find out your options for visiting the cave.

Scheduled Group Tours

You can take a boat tour from Herceg Novi marina departing 9am and 10am every day from April through to October (weather dependent).

These tours usually include a stop at Fort Mamula, a former Austro-Hungarian prison island, kind of like the Montenegrin version of Alcatraz and spend the afternoon at Zanjic or Miriste beaches. Scroll down to the map below to see where these are.

These tours are the cheapest option. Just keep in mind that in the height of summer they'll be packed and you might have to stand for the 45 minute rides to the cave and back. You'll probably also be blasted with Balkan pop music, but it's tradition for the captain to hand out shots of rakija - local brandy that's at least 40% alcohol - so you might be in the mood for the Balkan party atmosphere!

Price: €6-10 per person return.

Own Boat or Rented Boat

If you’ve rented a boat or have your own and want to head out to the blue cave, see the map below to see where it is. If you’re unsure about driving your boat into the cave you can also anchor outside either entrance and swim the few metres to the cave.

If you’re doing this, I highly recommend skipping Zanjic and Miriste beaches which are crowded and heading further to Dobra Luka. 

Dobra Luka

Dobra LukaDobra Luka has a tiny sand beach - perfect for a family

Dobra Luka – meaning ‘Good Bay’ -  is a strong contender for our favourite place in Montenegro – a big call, but we spend every minute we can there in summer.

It’s a sheltered bay, perfect for swimming, snorkelling, sunning and snoozing. If you’ve got some stress to get rid of, this place will rejuvenate you like the hands of a thousand Thai masseuses.

Unlike Oblatno further around which is popular with the yachts from Porto Montenegro and their accompanying jet skis, wakeboards and other toys, if you have any company here at all they’ll also be seeking peace and quiet.
