Much of downtown San Antonio can be explored on foot or by way of the trolley system that runs frequently between points of interest.
Depending on whom you ask, the number of neighborhoods in San Antonio varies. The San Antonio Convention & Visitors Bureau breaks the city into quadrants—Northside, Eastside, Southside, and Westside, with museums in the north, heritage sites on the east and west, and missions in the south.
For the purposes of this guidebook, we've broken San Antonio into five primary neighborhoods that fit where visitors tend to go. In the dining and lodging sections we've given the River Walk its own category due to the multitude of restaurants and hotels around the river's banks.
