Friends of Lake Sammamish State Park is inviting people to spend a hot summer Saturday night on the beach with friends, enjoying live dance, rock and pop music as the sun sets over the lake.

Beach Bash is set for 7 p.m. to 10:30 p.m. on July 13 at Lake Sammamish State Park.

The Aqua-Nets — “a full-energy party band,” according to a press release announcing the event — will take the stage with a mix of 1980s and ‘90s music. Costumes are optional.

Tiki bars will offer beer, wine and a signature event drink. Food trucks will be available.

Tickets are $30 per person until July 10, or $35 at the gate. Tickets include a complimentary beverage. Beach Bash is limited to adults 21 years old or older. Go online to www.LakeSammamishFriends.org to learn more and link to ticket sales at Eventbrite.

Beach Bash is hosted by Friends of Lake Sammamish State Park, a nonprofit organization dedicated to park improvements. Event sponsors include I-90 Motorsports, Roopika Mehra Real Estate, Grand Ridge Plaza at the Issaquah Highlands and Dru Bru Brewery.

An annual state park Discover Pass or $10 entry fee is required for admission to the park.
