Brodick is Arran's main town and the point of arrival for most visitors, built around a broad sandy bay where the CalMac ferry from Ardrossan docks after its 55-minute crossing. The town stretches along the shore with the dramatic ridge of Goat Fell rising steeply behind it, and on a clear day the combination of mountain, bay, and sea is genuinely impressive.
Brodick Castle, run by the National Trust for Scotland, sits in woodland above the bay and is the island's main attraction. The castle dates in parts to the 13th century and has fine collections of furniture, silver, and sporting trophies. The walled garden, established in 1710, is exceptional, with rhododendrons, exotic plants, and large trees that thrive in the mild Gulf Stream climate. The country park around the castle has marked trails through the woodland, and you can start the ascent of Goat Fell (874 metres) from here, a walk of about three hours to the summit with panoramic views over the Firth of Clyde. Glen Rosa, just west of Brodick, is the most accessible of the island's mountain glens and a beautiful walk in its own right.
The town itself is small and functional. There is a good range of shops, a Co-op for supplies, and several places to eat. The Brodick Bar and Brasserie does reliable pub food. The Isle of Arran Heritage Museum on Rosaburn Lane is a charming collection of local artefacts housed in old farm buildings, with unexpectedly interesting displays on the island's role in the early history of geology. Bikes can be hired in town for exploring the 90-kilometre coastal road that circles the island.
