When you have a car then you should definately take a tour along the shoreline. (Roadnr: C 255)
This path has numerous parkingplaces where you can rest and take beautiful pictures like the one on this page.
The tour will take you through several little towns and other places worthy of a visit.
When you drive all the way you'll end up in Loret de Mar and Blanes. These towns are VERY tourist minded.
