Flight
With the party being in Golden, DIA is your best bet for flights. The airport is a 40 minute drive away.
Train
There is a train that will take you from the airport to Golden with one transfer. Take the A line from the airport to Union Station and then get on the W line which takes you to Golden. From there, you can either call an Uber or Lyft to get you to your hotel/Airbnb if you're planning on staying in Golden.
Rental Car
If you want to rent a car, there is a shuttle that will take you from the airport to the rental car companies.
Hotel
Since the party is in Golden, we would recommend looking for accommodations around Golden. Table Mountain Inn: This is within walking distance to the Mountain Toad and is right in downtown Golden. https://www.tablemountaininn.com/ The Eddy Taproom and Hotel: This one is a little on the pricier side since it is a boutique hotel but it is also within walking distance to the brewery and has beautiful views of the foothills and Golden. https://www.theeddygolden.com/ There are also Airbnb options and hotels a little outside of Golden. Golden is pretty pricy so if that's a concern you can look for lodging in Lakewood, Arvada, or Wheat Ridge. Let us know if you have any questions!
