“Treasure the Beach” is a monthly beach cleanup that takes place on the first Saturday of every month. We partner with SOLVE, the City of Seaside, and Seaside Downtown Development Association, in our efforts to keep Seaside’s beach clean and healthy. To join us, you can register at solveoregon.org or just show up! Pick up your bags and gloves at the Seaside Aquarium located at 200 N. Prom, Seaside, OR from 9:00 a.m. to 11:00 a.m. Your bags of trash can be placed by any of the trash cans lining the Prom and the City of Seaside will come pick them up.
