Aspen is a compact town, and the conference venue and hotel are within walking distance of downtown shops and restaurants. However, for other transportation needs, there are several options.

Public Transportation

Aspen’s bus system is provided by the Roaring Fork Transportation Authority (RFTA) and serves routes throughout the town. The bus service within town is free. View maps and schedules at the RFTA website.

Bustang is a Colorado inter-city bus service.

Aspen Meadows Shuttle

The conference hotel provides a convenient, free shuttle into town that runs from 7 AM to 11 PM daily.


Some attendees elect to carpool from Denver (or other locations) to the conference location, and back again, reducing costs and making friends along the way! Check the up-to-date carpool requests and availability document for listings. To make a request, or volunteer carpooling services, email

Also, please join the discussion in the #rideshare-and-travel channel on the C++Now Discord. Here is the invite link.

Bike Rental

We-Cycle is available in Aspen. This system requires that you download an app to your smart phone and provide a credit card for security, but the first thirty minutes of every ride is free. Thirty minutes is usually enough for a trip anywhere in Aspen. The town of Aspen subsidizes this service to reduce parking in downtown Aspen.

Alternative Airports

While the Pitkin County Airport (ASE) is quite close to the Aspen Meadows and the Aspen Center for Physics, some may choose to fly into or out from other airports.  There are a few options for getting into and out of Aspen without necessarily going through ASE:

  • It is possible to rideshare or rent a car at Vail/Eagle (EGE). There are direct flights to EGE from ATL, DEN, DFW, EWT, IAH, JFK, LAX, LGA, MIA, ORD, PHL, PHX, and SFO. This drive is about eighty minutes.
  • It is also possible to rideshare or rent a car at Grand Junction (GJT). There are direct flights to GJT from AZA, DEN, DFW, LAS, LAX, PHX, SNA. This drive is about one hundred thirty minutes.
  • We also have attendees that choose to fly into Denver (DEN), rideshare or rent a car, and drive from there. This is about a four and a half hour drive.
  • It is also possible to take public transportation from DEN to Aspen. This requires two transfers. Take the train into Union Station, Denver, catch the Bustang to Glenwood Springs, catch RFTA into Aspen.
  • A number of attendees drive from home. For some this is the best option.
