The Zermatt Tourist Office is on Bahnhofplatz (tel. 027/966-81-00; www.zermatt.ch) and is open mid-June to September Monday to Saturday 8:30am to 6pm, and Sunday 8:30am to noon and 1:30 to 6pm. The rest of the year hours are Monday to Saturday 8:30am to noon and 1:30 to 6pm, and Sunday 9:30am to noon and 4 to 6pm.
Only a few of Zermatt's streets, notably Bahnhofstrasse, have names -- most don't. To find your way around, you can rely on the dozens of signs pointing the way to the various hotels and restaurants at the resort.
