Getting there

At 72 km (45 mi), Denver International Airport (DEN) makes arrival day a travel day. Open registration the evening before if you can.

This is an out-of-centre venue — 32 km (20 mi) from the middle of Boulder — which usually buys you parking and load-in access in exchange for a transport plan.

Boulder has 17 venues mapped in total and a population of 106,803. The Boulder guide covers the airport, the local time zone and what else is bookable nearby.

Formats this suits

This is a room for a workshop, a chapter meeting, a training day or one track of a larger programme. Anything with an exhibition attached needs a second space.

  • networking mixers

    An independent space with its own character, which a mixer benefits from more than a conference does.

  • fundraisers and galas

    A room with a personality is worth more at a gala than square footage is.

  • community meetings

    Room for 550 covers most community and member meetings.
