boy kayaking

Moss Bay, Lake Union, Seattle

For a unique Seattle birthday party experience, take your guests kayaking on Lake Union! Moss Bay, a well-known water-sports center that also offers many camps for kids, offers two different instructional group tours that can make for a memorable party: The Kids Piggyback Tour ($25/ kid, minimum 10 guests) includes a 15-minute instructional kayak session followed by a 75-minute tour of the lake, where a tour leader will lead the group around Lake Union, hugging the shoreline. After the adventure, you could retire to nearby Lake Union Park for cake and presents, or smaller groups can gather at the picnic tables at the marina. 

Details Tours are available May–September, on Mondays, Tuesdays, Thursdays, Saturdays and Sundays.

Ride the Ducks

Ride the Ducks, Seattle

Ride the Ducks is a party that floats! Book a group tour on one of these unique vehicles, which starts as a bus and then turns into a boat to continue the trip on Lake Union. During the trip, the wacky tour captain keeps the crowd laughing and singing along to fun music. For a special occasion, you can reserve tickets for a group of 10 or more; even if you have less than ten people, the Duck staff will recognize your child’s birthday with a special crown and attention. Reserve your group early, as Ride the Ducks gets very busy in the summer (or wait until the off season). The Ducks' facilities are small, so you’ll have to retire to another venue or your home for cake and presents.

Details: Groups of 10 or more are charged by the person: Adults are $30, kids ages 3–12 are $18 and kids up to age 3, $1. Duck tours run year round. Another option is to charter a Duck for a private party; call 206-441-3825 for information.

The Center's pond-boat party package includes 39-inch wooden pond boats for 12 kids and sailing instruction for up to two hours.

Details: A party package costs $175 for up to 24 participants. You get a table and tent for your two-hour time slot.

Tips for a great park party

  • Doublecheck the park website a few days before to make sure everything is open for business as usual.
  • Go to the park early, at least an hour ahead of the party start time, and stake out a table if you didn’t reserve a shelter. Mark your spot with a plastic tablecloth or balloons. Bring a big blanket or two in case you end up on the grass.
  • Be sure to have a way to cover food so flies and other critters don’t join your party. If you’re packing perishables, bring enough ice and a cooler for safety.
  • Pack extra towels, bottled water, sunblock and bug spray because you know that someone will forget theirs.
  • Have a back-up plan in case of rain.
