Since most visitors to Denver, Boulder, and Colorado Springs will probably be traveling between cities and also into surrounding areas, you will most likely want to rent a car. However, you can save a bit of cash by doing your downtown city exploring, which can be done quite conveniently using public transportation, at either the beginning or the end of your stay, and only renting a car when you plan to leave town.

Each of the individual city guides contain information on car rentals and public transportation.

By Plane

Although you can fly between Denver and Colorado Springs, it’s not nearly as economical as driving the 70 miles.

Some large airlines offer transatlantic or transpacific passengers special discount tickets under the name Visit USA, which allows mostly one-way travel from one U.S. destination to another at very low prices.
