Montenegro’s Old Royal Capital Cetinje is a beautiful, peaceful town well worth a visit on it’s own, but also the entry point to St. Petar’s Mausoleum. Perched atop Jezerski Vrh peak of Lovcen Mountain, the Mausoleum itself is not overly impressive, but the views from the top are spectacular. A quick 10 minute (steep) hike to the the rocky peak affords views of rugged mountains and the Bay of Kotor in the distance. Be sure to walk through the Mausoleum and along the narrow path to the guvno, a circular stone structure traditionally serving as a gathering point where important decisions were made.
From the capital Podgorica or the popular town of Kotor you can take a local bus to the Cetinje bus station. The trip from Podgorica is shorter, at around 30-45 minutes and a little cheaper (3.5€) than the 5€, 1.5 hour trip from Kotor.
From the bus station in Cetinje it’s best to take a taxi to the Mausoleum. It should cost around 25€ for the return trip, including an hour of exploring at the top. I split the trip with two fellow travelers, so it was very affordable at around 8€ each.
Entrance to the Lovcen National Park is 2€ per person and 5€ to the Mausoleum. You can still appreciate the view without paying for the Mausoleum entrance but the best view is at the end and well worth the fee.
