Dublin has been called a walker's town, with sights that are better appreciated on foot than by car or bus. But it's also a biker's town, for bikes give an intimate look at the town's attractions while letting visitors cover a lot of ground in a short time. These bike tours provide new, easy-to-operate bikes and a guide that takes you through low-traffic streets at a leisurely pace. The guide stops to describe various sites along the route, and a refreshment stop is included.

This flexible tour allows you to pay one price and travel all day, getting off to take a closer look at all the attractions that interest you most. Several companies offer similar services, but this one has reliable busses running at each stop every 15 minutes and knowledgeable drivers that regale you with stories, facts and songs as you explore.#13;#10;
