Getting to and around Boulder for Sundance 2027, with or without a car
Most visitors do not need a rental car for Sundance 2027. Boulder’s venue cluster is compact, roughly two miles across downtown and the CU Boulder campus, and several venues sit within about a ten-minute walk of each other. The harder question is getting from Denver International Airport (DEN) to Boulder, which sits about 35 to 45 miles away depending on route. That leg is where you actually choose between transit, a shuttle, or a car.
Denver airport to Boulder: your options
| Option | What to know |
|---|---|
| RTD bus (AB1 route) | Regional Transportation District runs public bus service between DEN and Boulder. Check RTD’s current schedule and fare before you travel; frequency and stops can change seasonally. |
| Shared shuttle vans | Door-to-door shuttle operators serve the DEN-Boulder corridor; book ahead during festival week since demand spikes. |
| Rideshare or taxi | Available but priced for a 35-plus mile trip; expect surge pricing during peak arrival and departure windows. |
| Rental car | Only worth it if you’re also planning day trips outside Boulder; adds parking cost and winter-driving risk for a trip where you likely won’t need a car once you’re there. |
Getting around once you’re in Boulder
Once you’re in Boulder itself, walking covers most of the festival footprint if you’ve picked lodging inside or near downtown. Boulder also has a local bus network (RTD’s Boulder-area routes plus the free HOP circulator that serves downtown and the CU Boulder campus), which is useful if your hotel sits outside easy walking distance. Rideshare works as a backup for late-night returns or bad-weather days.
Do you need a car at all?
If your hotel is inside the two-mile downtown/CU Boulder footprint, most visitors can skip a rental car entirely: walk or take the local bus between venues, and use a shuttle, transit, or rideshare for the DEN-Boulder legs on either end of your trip. A car becomes worth considering only if you’re staying in a regional town like Longmont or Broomfield for lower rates, or if you’re combining the festival with wider Colorado travel.
Winter driving, if you do drive
Front-range winter storms can bring sudden snow and icy roads, including on US-36 between Denver and Boulder. If you’re driving, check the Colorado Department of Transportation’s road conditions before you leave and budget extra time; a normal 45-minute drive can take considerably longer after a storm.
