Perast to Kotor Boat, 12 Hours
From Dubrovnik: Montenegro Boat Tour from Perast to Kotor runs through Select Dubrovnik d.o.o.. Rated 4.5 across 5,483 reviews. Runs 11 - 12 hours. From $59.
Speedboat trips to the Blue Cave, Mamula and Our Lady of the Rocks leave from Kotor all season, from $38 for three hours, and the most-booked option carries a 4.8 rating across 5099 reviews (see Blue Cave Without A Tour). Further north, Tara rafting starts around $56, and full Durmitor day trips from the coast run about 13 hours for roughly $120. Every listing here has a published from-price and free cancellation, except the Herceg Novi private boat, which does not.
Two practical things. Heat pushes everyone toward the water by midday, so morning slots on kayak and boat tours feel calmer, and the 4-hour options give real swimming time at the cave. If you are coming from Dubrovnik, note that the Debeli Brijeg border gets busy at the peak of summer under new biometric checks, so the guided day trips, from $56, handle timing and border formalities for you.

Check availability →Summer reshapes the roster in predictable ways. Tara rafting runs April through October, so by July the river has traded its snowmelt fury for warmer, steadier water that suits first-timers and families. In the Bay of Kotor, boat traffic peaks with the cruise calls, and morning Blue Cave departures sell out first. Prices hold through the season; the cheap seats are simply gone weeks ahead.
Most listings here carry free cancellation, which matters when July plans shift. Shared Blue Cave boats, from $38 to $45 per person, fill fastest in peak weeks, so lock those in before you fly. On arrival, remember the tourist tax: €1.00 per adult per night in Budva and Bar, with registration required within 24 hours. Confirm your meeting point the day before, since waterfront docks get crowded.
Summer is peak season in Kotor, with cruise traffic heaviest from May through September, so book boat trips early. Sea swimming along the coast stays comfortable from June to September, ideal for swimming stops at the Blue Cave. One practical note: if you are coming from Dubrovnik, border waits at Debeli Brijeg can stretch for hours in August, so pick a day trip that builds in buffer time.
