Beinn Tarsuinn

Beinn Tarsuinn stands on the Isle of Arran in North Ayrshire, the southernmost of four Corbetts on the island. It rises between Glen Rosa to the east and Glen Iorsa to the west, with steep slopes on all sides. The mountain is often climbed alongside Cìr Mhòr, its neighbour to the north, which it meets via a rocky ridge called A' Chìr. Walkers can choose between scrambling over A' Chìr or taking a gentler path along the ridge’s western side. Glen Rosa provides the usual starting point for most routes up the hill. The crossing of A' Chìr adds a scrambling challenge, but the two peaks can also be linked without it. The simplest and shortest route up Beinn Tarsuinn follows one of two ridges beside Coire a' Bhradain, both of which lead down into Glen Rosa. The mountain’s position between the two glens makes it a distinctive landmark on the island. Its rocky ridges and grassy slopes offer varied terrain for walkers. The views from the summit stretch across Arran and beyond. At the top, visitors find an open summit plateau with wide views over the island’s hills and coast. The rocky ridge of A' Chìr can be seen to the north, while Glen Rosa and Glen Iorsa lie below. The surrounding peaks of the Arran hills form a dramatic backdrop. On clear days, the Firth of Clyde and the mountains of the mainland appear in the distance. The summit itself is marked by a small cairn, a common feature on Arran’s hills. The route down usually returns the way it came, completing a satisfying circular walk.
