The Riverwalk (Paseo del Rio) is a nice relaxing walkway along the river one level down from the hustle and bustle of the downtown area. It is lined with hotels, restaurants, bars and trendy shops along with the usual stores and has a number of access points throughout the downtown area. It seemed cooler than the streets on the hot summer day I was there. Shop, enjoy a meal at a sidewalk café, listen to live music or just escape the fast pace of San Antonio. You can walk down the sidewalks or ride one of the boats that cruise the river every 1/2 hour.
