Doing the Arapahoe Shuffle
From Denver's incredibly modern and spacious international airport, it's just an hour and a half via a straight shot down I-70 East by car. Rental cars are unusually inexpensive at the airport for some reason. If you work for a corporation, be sure to ask for the corporate rate, which can sometimes be even less expensive than even the Internet specials.
For those who would rather not rent a car, Greyhound Bus Lines has 4 daily trips from downtown Denver to the Frisco transportation center for just $30 round trip.
From Frisco you can connect to the free Summit Stage to the towns of Breckenridge, Dillon, and Siverthorne, as well as to Arapahoe Basin via Keystone. To get from the airport to downtown, try SkyRide - http://www.rtd-denver.com/skyRide/
(Edit 6/23/05: Greyhound no longer serves Denver International Airport, so now you have to catch the Greyhound to Frisco from downtown Denver.)
If you do take Greyhound, a daylight trip is advisable, as the mountain scenery on the busride, which goes along a less traveled route than I-70, is spectacular.
The area has a great public bus transportation system called the Summit Stage, with frequent, free service over an extensive area. If waiting a little longer to get around isn't a problem, it's not even really necessary to have a car here.
The fleet consists of unusually sturdy busses that appear well prepared to deal with the severe weather and steep grades seen in the area. Each is equipped with a stereo system that charmingly plays soothing classical or New Age music.
The Summit Stage is an ideal place to mingle with the real people from the local population. With Bach playing in the bacground, among those with me on the bus coming back from the Breckenridge Rec Center: a 40ish man with very long hair and worn overalls who looked like a remnant of the hippie era, who disembarked at a trailer park; a couple of Hispanic men clad in workers attire speaking Spanish enthusiastically, who appeared to be recent immigrants or guest workers; a group of Gen X slackers discussing their plans to get drunk that evening and an upcoming trip to Baja Mexico.
A funky experience that I would highly recommend even if you came with a car.
