The iPerú tourist office is at Av. Luzuriaga 734 (Pasaje Atusparía, Of. 1), across from the Plaza de Armas (tel. 043/428-812); it's open Monday to Friday 8am to 1pm and 4 to 7pm. General tourist information is also available during the same hours from the tourist police office between City Hall and the Post Office on Avenida Luzuriaga (tel. 043/421-341). For mountaineering and trekking information, though, you're best off consulting the Casa de Guías, Parque Ginebra 28 (tel. 043/421-811). The office is open Monday through Friday from 9am to 6pm, and Saturday from 9am to 1pm. The friendly folks there have up-to-date information on trails, maps, lists of certified guides, and message-board postings for those looking to form trekking and climbing groups. Mostly, though, they're there to set you up with a guide. Basic information on visiting the Huascarán National Park can be obtained from the Parque Nacional Huascarán office, in the Ministerio de Agricultura building on Avenida Raymondi (tel. 043/422-086).
Tour Operators & Travel Agencies
Guides and travel agencies are extremely useful, if not downright indispensable, for most adventure sports in the remote and often dangerous mountains. Like Cusco and Iquitos, Huaraz is chock-full of agencies and tour operators. Unfortunately, some of them are less than reliable; others are far worse. It's best to check with fellow tourists (or, before arriving in Huaraz, with the South American Explorers clubs in either Lima or Cusco) to get recent reports about services.
