22030 Cliff Ave S, Des Moines, WA 98198
Wedding guest parking is pre-paid and attendants will be available to help starting at 3 PM.

Getting there

Input into your GPS:
22030 Cliff Ave S, Des Moines, WA 98198
By car: Des Moines Beach Park is about 25 minutes south of downtown Seattle via I-5.
If you are starting from Seattle or Burien it’s a bit more efficient to come down Highway 509.
Parking: Attendants will direct you to pre-paid parking.
Evening detour: The main street in Des Moines (Marine View Drive) will close after 5 PM for a parade, so if you leave the reception early you may need to follow a detour (or watch a parade!).

A note on the setting

This is a summer beach park wedding in the Pacific Northwest.
Daylight will last forever (9 PM sunset, nautical twilight ends at 10:30). But it’s not as warm as summer elsewhere in the US: our July average high is 74 degrees and evenings can drop into the 60s. 
We recommend wearing comfortable shoes for walking on grass, and bringing a sweater or light jacket if you want to be outside in the evening. (There will be coat racks and your car will be nearby if you want to leave anything there.)
Activities will begin outside on the lawn and shaded picnic shelter and move into the dining hall for dinner and dancing.
