If you're looking for a fun, educational, and family-friendly event this summer in Anacortes, be sure to mark your calendar for the 3rd Annual Pop-Up Aquarium. Returning to downtown Anacortes on Sunday, July 26, 2026, from 12:00 PM to 4:00 PM, this unique event offers visitors the chance to experience the incredible marine life of the Salish Sea without ever stepping onto a boat.
Hosted in the heart of downtown at 501 Commercial Avenue, the pop-up aquarium has become one of Anacortes' most anticipated summer events. This year's event is especially exciting as it will be welcomed into its new location by Dockside Dogs, creating an inviting atmosphere where visitors can enjoy both local businesses and hands-on marine education.
Best of all, admission is completely free, making it an affordable activity for families, visitors, and anyone curious about the fascinating ecosystems that make the Pacific Northwest so special.
Bringing the Salish Sea to Downtown Anacortes
One of the greatest things about living in Anacortes is the close connection to the water. Surrounded by the Salish Sea, Fidalgo Island is home to an incredible variety of marine life. Yet many of the creatures that live just beneath the surface often go unnoticed.
The Pop-Up Aquarium changes that.
Rather than requiring visitors to travel out on the water, the event brings carefully curated marine exhibits directly into downtown Anacortes. It's an opportunity to get up close with species that many people have never seen before while learning about the importance of protecting local marine habitats.
Whether you're a lifelong resident or visiting Anacortes for the first time, the event offers a new appreciation for the diverse ecosystems that make this region so unique.
Explore Interactive Marine Exhibits
This year's aquarium will feature several engaging exhibits designed to educate visitors of all ages.
Meet the Octopus
One of the most anticipated attractions each year is the octopus display.
Known for their remarkable intelligence, problem-solving abilities, and incredible camouflage, octopuses continue to fascinate scientists and visitors alike. Watching one move through its habitat provides a rare opportunity to appreciate one of the ocean's most extraordinary animals.
Get Hands-On at the Touch Tank
For many younger visitors, the touch tank becomes the highlight of the day.
Rather than simply observing marine life through glass, guests can safely interact with select tidepool species under the guidance of knowledgeable volunteers. This hands-on experience helps children develop a deeper understanding of marine ecosystems while encouraging curiosity and respect for ocean life.
Interactive learning experiences like these often leave lasting impressions that inspire future scientists, conservationists, and ocean enthusiasts.
Experience the Beauty of Jellyfish
The jellyfish exhibit offers a peaceful contrast to the more interactive displays.
Watching jellyfish drift gracefully through the water provides an opportunity to observe one of the ocean's most elegant creatures. Their unique anatomy and life cycle continue to intrigue marine biologists, making this exhibit both beautiful and educational.
Discover the Hidden World of Eelgrass Meadows
Many people are surprised to learn that some of the Pacific Northwest's most important marine habitats are found in eelgrass meadows.
This year's aquarium includes a tank dedicated to showcasing the diverse organisms that rely on eelgrass for food, shelter, and reproduction.
Eelgrass serves as a nursery for many fish species, provides habitat for countless invertebrates, and plays an important role in maintaining healthy coastal ecosystems. Learning about these underwater meadows helps visitors understand why habitat conservation is so critical throughout the Salish Sea.
Supporting Marine Science and Future Researchers
Although admission to the Pop-Up Aquarium is free, attendees are encouraged to consider making a donation to support an important cause.
All donations go toward the student travel fund, which helps graduate students attend scientific conferences, workshops, and professional development opportunities.
These experiences allow emerging researchers to:
- Share their latest scientific findings.
- Collaborate with marine scientists from around the world.
- Learn about new research techniques and conservation efforts.
- Build professional networks that advance marine science.
By supporting student travel, community members help invest in the next generation of scientists working to better understand and protect our oceans.
Every donation—large or small—helps make these opportunities possible.
Community Partnerships Make It Possible
Events like the Pop-Up Aquarium don't happen without generous community support.
Equipment, transportation, and interpretive educational materials for the event were made possible through a grant from VersaCare. This funding has allowed organizers to create a high-quality educational experience that continues to grow each year.
The grant also supported the commissioning of talented illustrator Meg Mindlin (@invertebabe) to create engaging artwork used throughout the event's educational materials. Her illustrations help make marine science approachable, colorful, and engaging for visitors of all ages.
These partnerships demonstrate what can happen when local organizations, businesses, artists, and educators work together to create meaningful community experiences.
A Great Addition to Your Downtown Visit
The Pop-Up Aquarium also provides a wonderful opportunity to spend the day exploring downtown Anacortes.
Before or after visiting the exhibits, guests can stroll along Commercial Avenue, browse locally owned boutiques, stop by coffee shops, or enjoy lunch at one of the area's many restaurants. The event's location makes it easy to combine marine education with everything else that makes downtown Anacortes such a popular destination.
Whether you're planning a family outing, entertaining visiting friends, or simply looking for something unique to do on a summer afternoon, the Pop-Up Aquarium offers an experience that's both memorable and educational.
Why Events Like This Matter
Marine ecosystems face increasing challenges from pollution, habitat loss, and climate change. Public education plays an important role in helping communities understand the importance of protecting local waters.
Events like the Pop-Up Aquarium connect people directly with the species that call the Salish Sea home. When visitors can observe these animals up close, ask questions, and interact with marine educators, conservation becomes personal rather than abstract.
For children especially, experiences like touching a sea star, watching a jellyfish drift through the water, or learning about the importance of eelgrass habitats can spark a lifelong interest in science and environmental stewardship.
That combination of education, community involvement, and hands-on discovery is what has made the Pop-Up Aquarium such a beloved annual tradition.
