After the ferry docks at Brodick, you may want to head for Arran's major sights, Brodick Castle and the Isle of Arran Heritage Museum .
The most intriguing walks on the island are signposted. But if you're really serious about hiking, buy one of two detailed guides at the tourist office -- Seventy Walks in Arran for £2.50 ($4.75) and My Walks in Arran for £2.25 ($4.30). While at the office, ask about any guided walks the Forestry Commission might be conducting. They are scheduled frequently in summer and range from 2 to 5 hours, costing £5 to £8 ($9.50-$15).
If you'd prefer to do your exploring on two wheels, stop by Mr. Bilsland, The Gift Shop, Brodick (tel. 01770/302-272). You'll have to show an ID; rental rates include a helmet and are £9 to £12 ($17-$23) daily £20 to £35 ($38-$67) weekly. It's open daily 9:30am to 6pm. Brodick Cycles, Brodick (tel. 01770/302-460), requires a £9 to £30 ($17-$57) deposit, depending on the type of bike. Daily rentals range from £10 to £12 ($19-$23), with £19 to £36 ($36-$68) for a full week. It's open in summer Monday to Saturday 9am to 6pm and Sunday 10am to 6pm.
South from Brodick is the village/resort of Lamlash, on Lamlash Bay. From here, a ferry takes you over to Holy Island with its 303m (1,000-ft.) peak. A disciple of St. Columba founded a church on this island. In the north, Lochranza is a village with unique appeal. It opens onto a bay of pebbles and sand, and in the background lie the ruins of a castle that was reputedly the hunting seat of Robert the Bruce.
Down a Lovely Glen with a Picnic in Hand -- The best way to discover the island's beauty is to stroll around. Right beyond the Isle of Arran Heritage Museum, at the point where String Road divides the island, you can follow the signs to a beauty spot called Glen Rosa. This is the island's loveliest glen, and you might want to pick up the makings of a picnic lunch before setting out. Another great walk is to the village of Corriegills, which is signposted along A841 south of Brodick. As you stroll, you'll be treated with the finest views of Brodick Bay.
