We had a great time city hiking in Ireland. While I didn't plan very well, everything turned out great. We hired a local driver to drive us 15 miles to 20 miles away from our hotel. We chose the locations based of maps that showed trails or country roads.
Local drivers dropped us off in small towns. When they learned what we were doing, their outside voice said it sounds like fun. However, their inside voice said that we were nuts. But this is how we travel. You get to see more taking the path less traveled.
We took backpacks that were loaded with water, cheese, crackers, a mini bottle of wine, and our Garmin ForeRunner. While we didn't need to tap into our supplies because we found many great places to stop in and grab a pint and a sandwich, we did actively use our Garmin watch. In fact, it became a super valuable tool to help us find our way back to the hotel.
