Vrmac is the ridge that separates Tivat from Kotor, and it gives Tivat its best walking without needing a long transfer. Trails climb through scrub and woodland to viewpoints over both sides of the bay.
The walking is not technically difficult, but summer heat makes it tougher than the map suggests. Start early, carry water, and consider descending toward Kotor if you want to turn the hike into a cross-bay route.
