The Montenegro Mountaineering Coastal Transversal is a 180 kilometer hiking trail connecting Orjen, Lovćen en Rumija. Also known as: Primorska planinarska transverzala (PPT).
Most parts of the PPT are well marked, a few km's are not. The less often parts are a bit overgrown. These are karst mountains; the trail is at times strenuous. Hiking the trail takes about 8-10 days. The trail follows the mountains above the Adriatic sea.
Bringing a tent (tarp) and food is necessary. Along the trail there are plenty of springs and cisterns. Bring something to purify the water. About halfway at Brajici there's a bus connecting to the coastal town of Bar (resupply).
Spring (may/june) is the best time to hike this trail, since the summers get very hot.
