Flight
DIA is the nearest airport. It is around 40 minutes from Denver, and 1 - 1.5 hours from the church.
House Or Rental
Houses in or near Evergreen will get you close to the ceremony location. Lakewood, Arvada, Denver, Golden, and surrounding areas are also good places to stay. It's around 40 min drive time from the Metro Area to Evergreen.
Train
This is the train from DIA to Union Station downtown. If you're headed to the Denver area, this could be a good option from the airport.
House Or Rental
A series of suites and cottages along Bear Creek. Incredibly beautiful and would make a wonderful place to stay, although a tad pricey.
