Kotor to Perast from the cruise port

1. Disembark 15min
2. Walk 3min
3. Bus 30min

Perast is a straightforward add-on to a Kotor call, not a detour: the coastal bus from just outside the port gate takes about 30 minutes, dropping you on the edge of the small waterfront town within sight of the church of Our Lady of the Rocks’ island. From there it’s a short walk along the water to the jetty for the water taxi out to the islet itself, plus whatever time you spend at the chapel and museum on it. Work backwards from your all-aboard: with a 30-minute bus each way plus the water-taxi crossing and a look around Perast itself, this trip alone can take two and a half to three hours door to door, so treat mid-afternoon as your latest sensible departure from Perast on a standard call.

Choosing Perast means trading away the fortress climb, or at least most of the Old Town’s slower corners — there usually isn’t time in one call for both the 1,350 steps and a relaxed water crossing to the islet. It’s worth it if the postcard view of the chapel on its own reef matters more to you than the bay-from-above view at San Giovanni; if you want both, this is the trip to save for a longer call or a return visit, not to squeeze into a short one.
