Dubrovnik is the gateway to the southern Adriatic — and only two hours from the Bay of Kotor. BookNRoll lists verified local guides on both sides of the border, so you can book Croatia and Montenegro in one place.
Dubrovnik's Old Town is compact and walkable, which means most visitors finish the headline sights in a day and a half. The city walls (best at 8am or after 5pm), the Stradun, Lovrijenac fortress and the Srđ cable car are the core.
The rest of a Dubrovnik trip is spent on the water and outside the walls: sea kayaking under the ramparts to Lokrum, Elaphiti island hopping, sunset cruises, and day trips south to Kotor and Perast in Montenegro.
Walk the city walls first thing in the morning, then Stradun, Rector's Palace and the Franciscan monastery pharmacy. Take the cable car up Srđ for sunset over the Elaphiti islands. If you only have one afternoon activity, make it a kayak tour — it is the only way to see the walls from the sea.
Sea kayaking around Lokrum island (3h, from €35). Elaphiti islands boat day (Koločep, Lopud, Šipan, from €60). Game of Thrones walking tour (2h, from €25). Konavle valley wine and olive oil tasting (5h, from €55). Buggy or ATV safari above Župa Dubrovačka.
The Debeli Brijeg border is about 45 minutes from Dubrovnik; Kotor is roughly 2 to 2.5 hours depending on the queue and whether you take the Kamenari–Lepetane ferry. A private transfer is €90–€140 one way for the car, and a guided Montenegro day trip from Dubrovnik runs €50–€75 per person.

Dubrovnik is the most expensive city in Croatia in July and August. Activities themselves are comparable to Montenegro (€25–€80), but food and accommodation inside the walls cost roughly 30–50% more than in Kotor.
