3 Days in Montenegro

What time of year and will you have a car? Flying in to Podgorica or somewhere else via bus/car? Do you like beaches or mountains more? since Montenegro has plenty of both.

Edit: ok I found a previous post saying you are staying in Lustica Bay and flying on to Venice after these 3 days.

Take a drive (or hire a guide and have them drive you for more enjoyment) for the day to Lovcen and Cetinje.
Take a boat tour to the Blue Cave (it will include other stops).
Drive to Budva and explore the Old Town. Maybe Kotor if you find a day without a cruise ship.

Thank you. That all sounds doable.

In all the coastal cities I went to (which is not all the interesting ones), I found inexpensive boat rides you just walk up to. In Budva, I had no idea where it was going but it was a round trip for €10 and it went to more gorgeous beaches and views.
