Known as one of the greenest cities in America, Boulder, Colorado boasts a terrific bus system and plenty of walking and biking trails to connect you anywhere you need to go in and out of town.
However, due to the extensiveness of the Boulder bus system, navigating your way around can be rather intimidating if you're unfamiliar with the fees, transfers, and strange route letter and number combinations.
Whether you're traveling to Boulder or have just moved to the city, familiarizing yourself with the bus routes and understanding how the bus network operates will prepare you for getting around this pedestrian-friendly mountain town.
Explaining the Bus Network
There are two main bus networks that serve Boulder: the Regional Transportation District (RTD) and the Community Transit Network (CTN), and fares in 2018 are $2.60 one-way on the CTN, $4.50 one-way on the RTD ($9 for a day pass), and $9 one-way to the airports.
The RTD is a large, independent network of bus and light rail routes that serve the entire greater Denver area, from Boulder to Denver International Airport. The Community Transit Network, while managed and operated by RTD, is a separate fleet of buses that specifically transport passengers through Boulder and connects with regional lines.
Although technically separate entities, the RTD and CTN work in tandem to provide bus and train service to get you pretty much anywhere in Boulder.
Fares for local routes generally run $2.60 one-way, but you can also buy ticket books or monthly and yearly passes; for Skyride, the fares are $9 to $13, depending on your place of departure.
