Mexico is well known for their excellent transportation systems. However, everything you need can usually be found in close proximity to all accommodations. Walking, biking, skateboarding is a great way to burn off a few calories without having to worry about finding that elusive good parking spot. Just make sure to keep an eye on where you are going as the sidewalks, pavement and cobblestone streets are notorious for potholes and oddly placed things (trees, posts, cables) For longer distances there is several platforms/classes of buses, vans, taxis, rental cars and tour operators. You should expect to be able to get anywhere safely and at an affordable rate.
