MaST Center Aquarium
The MaST Center Aquarium fosters a culture of marine stewardship by engaging our community through interactive learning, personal relations and exploration.
In 2023, we celebrated our 20th anniversary and our best year ever with 14,000 visitors, along with over 100 programs for our community!
The MaST Center Aquarium is the marine biology and aquarium facility of Highline College. Dedicated to expanding knowledge about Puget Sound, the MaST Center Aquarium serves as both formal teaching institute and public learning center. We are located 4 miles south of campus at Redondo Beach with easy access to a variety of nearby habitats.
Our 2,500 square-foot facility offers public space, classroom, laboratories, offices, research areas with state-of-the-art equipment and an aquarium. The Aquarium holds over 15 tanks totaling approximately 3,000 gallons of flow-through seawater, and displays over 250 native Puget Sound marine species.
