Puget Sound Estuarium

The Estuarium is a marine life discovery center featuring aquariums and interpretive exhibits. Outside our facility, we can be found on local docks and beaches connecting people of all ages to our delicate and vibrant estuarine ecosystem. The Estuarium also provides K-12 education resources and field trips to local schools. Our volunteer program offers unique hands-on opportunities to explore intertidal life and inspire community members to take better care of our shared natural resources.

Our facility is home to saltwater aquariums and a diverse specimen collection featuring amazing intertidal and subtidal estuary plants and animals. Our hands-on interactive exhibits include a video screening station, microscopes, rotating arts and crafts projects and more. The Estuarium highlights topics during our rotating exhibits complete with special activities! Rotating exhibits often feature special guest speakers, dissections, and demonstrations led by our lead interpreters. Exhibits include:

  • Ways to Make a Difference Exhibit
  • Plastic Pollution Exhibit
  • Cultural Exhibit
  • Rough Skinned Newt Tank
  • Shellfish Tank and Exhibit
  • Eelgrass Tank
  • Asteroidea Tank
  • Estuary Predator Tank
  • Microscope Station
  • Movie Station
  • Estuary Inspired Arts and Crafts


  • Meet the Beach – During our Meet the Beach program our dedicated team of volunteers, called Beach Naturalists, connect beachgoers with our unique estuarine ecosystem by identifying intertidal life during summer low tides.
  • Pier Peer – Year-round our trained staff and volunteers run our popular Pier Peer program on local docks after dark in Thurston and Mason Counties. Our trained team provides underwater lights that attract spectacular estuary creatures for you to scoop up and observe.
  • K-12 Education: The Estuarium offers extensive educational programming and a variety of estuary and marine ecology topics for Pre-K through 12th grade students. Our programs offer students unique hands-on activities and are linked to the STEM standards, Next Generation Science Standards (NGSS), and Ocean Literacy Frameworks.

Volunteer & Internship Opportunities
The Estuarium relies on our dedicated volunteers to help run our programs and facility. Estuarium volunteers are encouraged to participate during field trips, Pier Peer and Meet the Beach events, assisting in animal husbandry, and serving as interpreters during our weekend open hours. Internships are periodically offered at the Estuarium. Interns are invited to learn a wide range of skills from nonprofit management, animal husbandry, K-12 education and more. Please contact our Program Coordinator to learn about our current internship opportunities.

Teacher Resources
The Estuarium offers School Estuary Kits for local K-12 teachers with 3rd – 12th grade students. All kits include enough materials for a group of 30 students and the content is designed for age-appropriate learning. The School Estuary Kits support current NGSS educational standards.

Do you have a group you think would enjoy a private Meet the Beach, Pier Peer, or Estuarium tour? Please email us to inquire about private programs, rentals, and Estuarium birthday party packages.

Capitol Land Trust

Capitol Land Trust
Capitol Land Trust’s mission is to conserve essential natural areas and working farms in southwest Washington. Since 1987, we have grown from a volunteer organization to a professional and accredited land trust. With the help of our supporters and partners, we have successfully conserved over 6,000 acres of land on nearly 80 properties in Thurston, Mason, Grays Harbor, and Lewis counties. The land we conserve is protected forever.

Visit us
We have a small working office in Lacey, WA. We don’t offer any programs or exhibits at our office location. As of 2020, we have four preserves that are open for public use. If you plan a visit to one of our nature preserves, be sure to visit our website for the most current information. In general, our walking trails are mulched or dirt trails and vary in elevation and length. Walking on our trails, you’ll pass many Pacific Northwest ecosystems including wetlands, forests of varying ages, marine shoreline, open oak woodland, and fish-bearing streams. Please contact us if you plan to park a vehicle larger than a 12-passenger van on a property because some sites have space restrictions.

Educational Programs

  • Guided nature walks
  • Land Stewardship and Restoration – Learn how to identify native and invasive plant species and keep our ecosystems healthy. These activities include removing invasive species, planting native plant species, and addressing other needs the land may have.

Volunteer & Internship Opportunities
Volunteers are essential to our mission, and we strive to create a volunteer experience that is both meaningful and enjoyable. As a Capitol Land Trust volunteer, you further our mission by stewarding natural landscapes, educating the next generation, and connecting people with our conserved lands. With your help, our area continues to have thriving natural habitats and green spaces to enjoy.

  • Stewardship Work Parties – Weekly stewardship work parties occur year-round between October and July, and typically include activities like planting native plants, mulching, removing invasive species or debris, and maintaining trails.
  • Environmental Education – We work with several schools and youth-serving organizations to provide field experiences for youth on our conservation properties. Most of the activities that take place during these experiences are run by volunteers. We provide a volunteer training for our 7th grade field experience and our 3rd grade field experience.
  • Trail and Land Stewards – Trail Stewards and Land Stewards make sure our properties are safe and healthy!

Billy Frank Jr. Nisqually National Wildlife Refuge

The Billy Frank Jr. Nisqually National Wildlife Refuge is managed by the U.S. Fish & Wildlife Service and provides numerous recreation opportunities to thousands of visitors every year. Whether boating, walking the trails, or participating in educational programs, visitors enjoy viewing the unique ecosystems and diverse wildlife. Regulation of recreation activities allows for public enjoyment of the refuge while still protecting the wildlife and habitats. The Nisqually estuary was restored in 2009 by removing dikes and reconnecting 762 acres with the tides of Puget Sound. This is the largest estuary restoration project in the Pacific Northwest and an important step in the recovery of Puget Sound. Many visitors, especially birders and boaters, have found that it is best to plan a visit to the Refuge according to the tides. The highest concentrations of the estuarine bird species will be most visible within two hours of high tide. The Visitor Center includes The Nature Shop, an information desk, a view of the freshwater marsh, and interpretive exhibits.

Visit Us
Educational Facilities include the Refuge’s Environmental Education Center and four miles of flat boardwalk & gravel trails. The Environmental Education Center is open by appointment only. Educational groups Pre-K through college may request use of the Environmental Education Center and assistance from Refuge Educators.

Educational Programs
The Refuge’s Environmental Education Programming is designed to meet the needs of visiting groups. Please contact our education coordinator to plan your trip. Indoor activities cover a wide range of wildlife-related topics including:

  • Habitat
  • Animal Adaptations
  • Animal Tracks & Signs
  • Bird Identification
  • Developing Observation Skills
  • Citizen Science

Educator Training
Four field trip orientation workshops are conducted each year. We encourage all educators planning a trip to the Refuge to attend to get all the tools you need to confidently guide your students on a meaningful outdoor learning experience. You will be introduced to our hands-on indoor activities in our Environmental Education Center, hike the Twin Barns Loop Trail, and learn about one of the largest restoration projects in the Puget Sound! Refreshments will be provided. Dates can be found on the Refuge’s website.

Volunteer & Internship Opportunities
Volunteer & Internship Opportunities exist with the Refuge’s Environmental Education program as well as other programs at the Refuge. More than 42,000 people volunteer their time and ideas each year to the U.S. Fish and Wildlife Service. Whether they work on the land, in a visitor center, or with youth, they contribute to the conservation mission that reaches back more than a century. Become a volunteer to contribute your strength on behalf of America’s natural resources.
