At the beginning of Summer, I took my two daughters to go and check out the Living Coast Discovery Center, located in the San Diego Bay National Wildlife Refuge. I had not been there for over 30 years, so needless to say I was super excited to go back!
Where is the Living Coast Discovery Center?

Discovering the San Diego Bay National Wildlife Refuge
The San Diego Bay Wildlife Refuge is comprised of over 316 acres of salt marsh wetlands and coastal uplands that are surrounded by urban development. The Refuge, dedicated in 1999, has the primary objective of protecting the remaining salt marshes and mudflats in the south part of the San Diego Bay.
The Living Coast Discovery Center, established in 1987 is located on 46 acres in what is known as the Sweetwater Marsh National Wildlife Refuge, which was established in 1988.
Parking is available offsite. There is a shuttle that comes every 15 minutes to take patrons directly to the Living Coast Discovery Center.
The San Diego Bay National Wildlife Refuge is part of the Pacific Flyway-a major north-south flyway for migratory birds. San Diego Bay is a crucial resting spot where hundreds of thousands of birds stop to eat and rest while making their migration. Some species end up staying the whole winter while others just stop by for a few days.
Are you ready to see The Living Coast Discovery Center now?
First Stop, Turtle Lagoon
The shuttle lets us off right in front of the Living Coast Discovery Center and the Turtle Lagoon. Here you will see the eastern Pacific green sea turtle which is native to the Southern California coastline and nests off of Baja California, Mexico.
All sea turtles in U.S. waters are listed on the Endangered Species Act. Here at the center, you will learn how pollution affects the turtles and things that you as an individual can do to help, such as making sure your trash does not get into the ocean.
For instance, turtles and other marine animals often mistake plastic bags for jellyfish, so they end up ingesting them. Because the plastic will not break down in their gut, it will cause a blockage, and they will eventually die from malnutrition.
Let’s Go Inside the Living Coast Discovery Center
As you look at the photo above, you can see that there are many opportunities to get up and close with the creatures here. How cool would it be to watch them feed the different animals? I wish that we stayed to watch the Eagles being fed. Maybe next time.
I love how they set-up this place. Once entering you will first encounter displays that concentrate on the Bay followed by the Marshlands and finally concluding with the information on the Uplands.
The Bay displays concentrate mainly on the saltwater marine life. Here you will see examples of fish that are found in the bay as well as jellyfish, moray eels, sea horses and many more.
The Marsh is considered a transition zone between the uplands and the bay. For example, the marsh absorbs flood waters, filters pollutants as well as provide food and shelter for many species.
The tides affect the marshlands every day. Mudflats and tidal channels are exposed when the tide goes out. This exposure, in turn, provides food for shorebirds as well as other creatures. With the incoming tide, more food supplies enter the marsh, and any exposed invertebrate or plant are replenished.
Due to human development, many of these critical marshlands have disappeared. It is essential to preserve these wetlands for future generations to come as they are vital to a healthy environment.
Protecting and restoring, and not to mention public involvement, are just a few of the main goals here at The Living Coast Discovery Center.
Sweetwater River Watershed
The photo above maps out the Sweetwater River which starts up in the Cuyamaca Mountains in San Diego County and travels 55 miles southwest until it finally empties into the San Diego Bay at the Sweetwater Marsh. I find it so fascinating that the Sweetwater River basin is over 231 square miles!
Here we have some information about several endangered plants and animal species that reside at the San Diego Bay National Wildlife Refuge/The Living Coast Discovery Center.
Let’s now head outside and go check out the sharks!
Shark and Ray Experience
I have to say that this was one of our favorite exhibits! The tank is quite large, 22,000 gallons in fact, with many sharks and rays within to observe. I also appreciate how they incorporated several San Diego Bay fish inside the tank as well!
List of Sharks and Rays in San Diego Bay
- Leopard shark-Triakis semifasciata
- Gray smoothhound shark-Mustelus californicus
- Horn shark-Heterodontus francisci
- Bat ray-Myliobatis californica
- Shovelnose guitarfish-Rhinobatos productus
- Round stingray-Urobatis haller
After checking out the outdoor Shark and Ray tank, we continue our exploration taking a look at a few of the coastal salt marsh shorebirds that are found here in San Diego.
Here we have the elusive and endangered light-foot Ridgeway’s rail which is only found in southern California and northern Baja California, Mexico.
This medium-sized salt marsh bird lives down close to the water in the lower littoral zone (underwater except during a shallow tide) where eelgrass and cordgrass are most dense. They rely on this grass to build their nests up upon. They also require shallow water and mudflats for foraging, as well as tall vegetation to hide in when the tide is high.
The light-footed Ridgeway’s rail is what you would call an indicator species. In other words, if this species is living in the wetlands, you can assume that the environment is healthy and biologically diverse. So protecting the light-footed Ridgeway’s rail’s habitat protects the entire environment as well as us humans.
If you would like to learn more about the breeding program of the light-footed Ridgeway’s rail at The Living Coast Discovery Center, click here.
Fun Fact- The Living Coast Discovery Center is the only zoological institution in the world that has the endangered light-footed Ridgeways’s rail species on public display.
A Few San Diego Bay Native Shorebirds
- Light-footed Ridgeway’s rail- Rallus obsoletus
- Snowy egret-Egretta thula
- Black-crowned Night-heron-Nycticorax nycticorax
- Black oystercatcher- Haematopus bachmani
The Living Coast Discovery Center has one of the best variety of raptors on display that I have ever seen outside of a public zoo. Here you can see several native birds of prey up close and personal. Once daily, you can also have the opportunity to watch as the keepers feed each bird individually.
Southern California Native Birds of Prey
- Red-tailed Hawk- Buteo jamaicensis
- Red-Shouldered Hawk- Buteo lineatus
- Osprey- Pandion haliaetus
- Peregrine Falcon- Falco peregrinus
- Turkey Vulture – Cathartes aura
- Barn Owl- Tyto alba
- Great-horned Owl- Bubo virginianus
- Burrowing Owl- Athene cunicularia
- Great Roadrunner- Geococcyx californianus
- American Kestrel- Falco sparverius
My daughters and I were so excited to be able to see a Bald Eagle and a Golden Eagle up so close!
Here we have Franklin, the resident bald eagle who due to a wing injury, is also unable to be reintroduced back into the wild.
How about a few interesting Bald Eagle facts? Like, did you know that the internal temperature of a bald eagle is 106 degrees Fahrenheit? Or that the average lifespan is 20 years? There was a captive bald eagle in West Stephentown, NY that live to be 48 years old! One more! Did you realize that the scientific name, Haliaeetus leucocephalus means “white-headed sea eagle?”
Here we have Dorado, a Golden Eagle. His right wing was damaged when he was hit by a car, so he also is unable to be reintroduced back into the wild. I sure had a bunch of fun watching him rock back and forth on this swing. He was having so much fun swinging too!
Golden Eagles are the largest bird of prey in North America. Did you know that golden eagles hunt large mammals and even fight off coyotes and bears when guarding their prey? I sure didn’t.
Native Pollinator Garden
We are now back out in the front of The Living Coast Discovery Center to check out the newest exhibit- The Native Pollinator Garden.
Here you will find several native plant species as well as suggestions for native southern California landscaping. As you are probably aware, San Diego does not get much rain, so drought tolerant plants survive here the best.
It wasn’t too long ago that we were not able to use sprinklers at our home, due to an emergency drought ban. Even though the ban was lifted in August of 2017, water conservation is still encouraged. To be honest, it is just the way of life here for all of us that live in Southern California. Water is our most precious commodity.
In this exhibit above, there have several different spots for bees to nest in. There is also information on other natural pollinators that live in the salt marsh; such as hummingbirds and butterflies. Each species has its role when it comes to the biodiversity of the habitat.
The primary goal of this exhibit is to increase awareness and educate future generations on the importance of bees, butterflies, and hummingbirds to not only the coastal environment but in all habitats.
Walking the Trails
Now we come to my most beloved part, walking the trails! I encourage you to visit all of the exhibits before setting off, as you will learn vital information that will help you enjoy yourself even more.
Ready? Let’s go!
We started our adventure by first walking straight and then making the first left. We eventually ended up at this small pool of water which had a small deck as well as an observation hut just to the left of it. Let’s check it out, shall we?
Now let’s go and walk back toward the middle of Sweetwater Marsh and see what we can see.
The History of Gunpowder Point
Gunpowder Point is where The Living Coast Discovery Center is located at the Sweetwater Marsh.
Back in 1916, this was the site of a kelp extracting company-Hercules Co. which made smokeless gunpowder called cordite for the British Troops in WWI.
From 1916-1919 over 1000 employees were making this gunpowder around the clock. Upon further research, I found out that each employee ended up receiving an honorable war medal from the U.S. Government to commemorate all that they did to help win the war.
In 1920, a Cottonseed Oil Company bought the abandoned Hercules building to store its oil. Unfortunately, in 1929 the entire building burned down in a fire. I just love finding all of this stuff out! It makes these discoveries all the sweeter!
Here is that site of one of the old storage tanks surrounded by sage plants. Down below is another piece of the history from Gunpowder Point.
Fun Fact-Have you ever heard of the film, “Attack of the Killer Tomatoes?’ The movie was filmed here at Gunpowder Point in 1978.

I have always had a deep-seated passion for the Ocean Environment which ultimately led me to receive a degree in Marine Biology. Living in the San Diego area for over 30 years, I have extensively explored the 70 miles of San Diego’s coastline, and I am here to share! Please use my website to your advantage and have a look around at all the wonders that the beaches of San Diego can offer you!
