I bought this guide the day before I left for Paris, mainly due to the crisp bird's-eye illustrations of the different walking routes. I rented a bike and was able to do 7 of the walks. However, I don't recommend doing some of the walks like the Ile de Cite one on a bike due to one-way streets. I was particularly impressed with the Left Bank Impressions walk with nice boutiques, galleries and outdoor snack stands along the way. The Latin Quarter walk, the Marais walk and the Island Hopping walks were similarly impressive. Every street corner was worthy of a picture. The authors definitely researched these walks thoroughly and I highly recommend this guide to first-time and returning visitors to Paris to get their bearings on this marvelous city.
