If the town you’re visiting is near the ocean or a river, drive down to the shore, park your car, and go get your feet wet. Take advantage of water-related activities that may be available. Go swimming, boating, sailing, fishing, kayaking, or just lie on an inflatable raft and soak up some sun. Many waterways have free or inexpensive ferries that can give you a pleasant ride, with a perfect view of the waterfront and wildlife. If the town you’re visiting is in the mountains or the desert, there are sure to be fantastic walking trails nearby, or maybe even a state park. Taking a free walk to see native plants and wildlife is one of the most relaxing, memorable vacation excursions, and it doesn’t cost a penny.
