Local Information


Flights are typically booked to Denver International Airport, from which it is about a one-hour bus ride to downtown Boulder. When arriving at the airport, go out the south end of the terminal (a main exit) and down the long escalator, purchase a ticket for $10.50 at a kiosk, and catch either the AB1 or AB2 bus that comes every hour until 11pm.

International travelers are responsible for complying with COVID-19 rules in both the U.S. and the country/ies they fly from. For U.S. rules, we suggest beginning with the CDC website, including travelers prohibited from entry. For visitors seeking COVID-19 tests, we can recommend these links:


Because August 15-19 overlaps with the university students' move-in week, we recommend booking accommodation in advance. Unfortunately, hotel prices will be higher than normal. AirBnB is also a common option in Boulder.

Local Tips

  • Altitude. Boulder, Colorado is about 5400 feet (1650 meters) above sea level, a moderate but noticeable elevation. You can minimize the impact by staying hydrated; more information here.
  • Weather. Boulder in the summer generally has cool nights (50F - 65F; 10C - 18C) and dry, hot days (75F - 95F; 24C - 34C), with very strong sun (due to the altitude) and common but short-lived afternoon rain storms. Sunglasses and sunscreen are recommended for spending significant time outdoors not under cover. (The conference will have a tent for our outdoor activities to provide shade and rain protection.)
  • Outdoor activities. Boulder is known for its beautiful hikes, accessible within only a couple miles from the university campus. The city also has many biking and running paths; venture a few miles from downtown and you will encounter herds of cows and colonies of prairie dogs.
  • Other activities. Boulder and the Denver area also have fun and COVID-safe opportunities such as music and outdoor restaurants. Denver is accessible by a bus ride of an hour each way.
