Toremar (tel. 0586/896113; www.toremar.it) operates ferries from the Porto Mediceo in Livorno to Capraia; in high season, there's a boat every day at 8:30pm; additional boats run on Thursdays (departing Livorno at 4pm) and Saturdays (departing Livorno at 3pm). The trip to Capraia takes about 2 1/2 hours and tickets cost 15€ one-way. On Tuesdays and Fridays, the Toremar ferry also stops at Gorgona along the way. A faster option, Consorzio Marittimo Turistico 5 Terre (tel. 0187/732987 or 0586/905089) also offers a private boat shuttle service between Livorno and Capraia in July and August. Daily departures from Livorno leave at 8:30am and arrive in Capraia at 10:10am; from Capraia to Livorno, the boats are at 4pm Monday through Friday and 5:30pm Saturday and Sunday, arriving Livorno at 5:40 and 7:10pm, respectively. Tickets are 15€ each way. The private shuttle service is suspended in inclement weather, while Toremar's tough old boats can handle rough seas just fine. Cars are technically permitted on Toremar's ferries (the faster boat service doesn't transport vehicles), but with Capraia's only paved road being about 800m long/2,625 ft., it would be rather pointless to bring a car here.
The inhabited parts of Capraia are easy to reach on foot from the ferry dock; the old borgo (walled town) is up on the promontory that forms the eastern boundary of the bay of the port. Additionally, there are 14 hiking paths and mulattieri (old mule trails) throughout the island. But the best way to appreciate Capraia's natural endowment is by boat. The classic, can't-miss excursion is the 2-hour giro dell'isola (around-the-island tour). A bus runs the short length of asphalt between the ferry landing and the town, handy if you're hauling luggage; otherwise, this distance is very pleasant to cover on foot. Neither mopeds nor bikes can be rented on Capraia -- this is strictly a walking or boating island.
Pro Loco Capraia, Via Assunzione, Capraia Porto (tel. 0586/905138; www.prolococapraia.it), is the volunteer-run tourist office at the port. Stop in here for island maps that detail hiking paths and the best coves to hit by boat.
