Using your smartphone to look up a museum address or get turn-by-turn directions on a street in a foreign city can end up costing a small fortune in data charges. Those who download Google Maps’s new Offline Maps won’t have to pay a dime.

The tool allows users to be in a place without Internet access — whether on a sidewalk in New York City or a back road in Tuscany — and pull up a map that lets them get directions and use turn-by-turn voice navigation, as well as search for places (art galleries, restaurants, hotels, museums) and see details including hours, phone numbers and reviews.

Offline Maps, introduced this month, is one of a handful of free tools being rolled out by Google as the company further extends its reach in the travel realm. It also recently began promoting a rewards program for people who post online reviews and tips about restaurants, concert halls, botanical gardens, hotels, shops, markets, museums and practically any other place one might want to go, as part of Local Guides.
