San Antonio International Airport (tel 210/207-3411, ) is just north of the I-410 loop which encircles most of the sights. SA Trans Shuttle (tel 1-800/868-7707) makes the twenty-minute journey downtown ($9 one-way, $16 round-trip; every 10-15min 4am-1am), while normal city buses cost only 75¢ but take nearly an hour to make the same trip. Taxis cost about $15 (Yellow Cabs tel 210/226-4242). Amtrak arrives centrally at 350 Hoefgen St, while Greyhound operates from 500 N St Mary's St. Pick up information on city transport from the visitor center at 317 Alamo Plaza directly across from the Alamo (daily 8.30am-6pm; tel 210/207-6748 or 1-800/447-3372, ), or call the VIA Metropolitan Transit Service (tel 210/362-2020, ). Buses are reliable; journeys within the I-410 loop cost 75¢, and many downtown routes run until 10.30pm. Four downtown streetcar routes serve the major attractions for 50¢, from Alamo Plaza.

Gray Line's bus tours (tel 210/226-1706, ) are only really of much use as a way to see the most distant missions (3 1/2 hr; $22), though VIA's #42 service from the Alamo does stop at the San Jose mission. The very enjoyable $5.25 boat tours (tel 210/244-5700), which do a leisurely 35-minute circuit of the River Walk, depart from two locations, just below the bridges on Commerce Street and Market Street.
