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.

Aspen Meadows Shuttle

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

Ride Sharing

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
