These are the places you should definitely try to see if you are visiting Herceg Novi in the summer:
This little lagoon is an amazing, quiet place with unbelievably clear water. You can get a boat ride from the main promenade in Herceg Novi which should not cost more than 5 euros.
While you are there, you can visit an ancient fortress that the Romans initially build in order to control the Bey enterance.
Or you can walk over to a larger lagoon called Zanjic, where the beach is made of larger pebbles and the water is quite deep and pristine.

2. Plava spilja (Blue Grotto)
This is a small cave on Lustica that you can also get to by boat from Herceg Novi. It got it’s name from the incredible blue color of the seawater and it is another gem of the Bay that not too many people get to enjoy.
