Assan through the Ages
- Type: Article

Assan Beach, the 2,500-yard shoreline stretching between Punta Adilok (Adelup Point) and Punta Assan (Asan Point), which the Marines in World War II called a "pair of devil horns," is a poignant symbol of the Guam's complex history, blending indigenous CHamoru traditions, wartime struggle, and ongoing military presence. In many ways, the story of Guam can be read through the story of Assan Beach. Talk a walk through history at Assan Beach.
Agat Unit - Apaca Point and Ga'an Point
- Type: Place

Hågat (Agat) Beach was the southern landing beaches used during the Battle of Guam. The rocky outcrops along the beach had been well fortified with caves and bunkers built directly into the limestone headland. With gunports for eyes and rocky ridges for armor, Japanese soldiers turned the terrain itself into a deadly defense. Today, the remains of those fortifications, as well as two examples of Imperial Japanese guns, stand against a backdrop of clear blue ocean.

Each year, millions of tons of plastics enter our world’s oceans. It’s the equivalent of one garbage truck of plastic dumped into the oceans every minute! Ocean plastics don’t just ruin the view, they also harm wildlife, damage coastal habitats, impact local economies, and even threaten human health. Find out how you can help.

Federally endangered coho salmon and threatened steelhead trout are large, charismatic fish that play crucial roles in both stream and ocean ecosystems. The National Park Service Inventory and Monitoring Program and its partners began monitoring coho and steelhead in Golden Gate National Recreation Area and Point Reyes National Seashore in 1998.

Limantour Beach is wide. Bookended by ocean on one side and grassy dunes on the other, its sandy expanse provides a habitat for many organisms that rely on the rich ecosystem between land and sea. The western snowy plover, a small brown and white shorebird, is one species that finds refuge in the sand. Over time, human activity and development have degraded many beaches like Limantour, and biologists have seen those impacts through the eyes of the snowy plovers.

At night, birds use the stars to find their way (pretty cool, right?). But bright lights from buildings, towers, and houses can confuse them. That's why national parks are so important - they're like bird hotels! They give birds safe places to rest and eat, especially after flying across the ocean.

Ocean Beach
- Type: Place

Ocean Beach is a great hang. The sunniest months are September and October, but O.B. always draws a crowd. San Francisco tends to be cool and gray, even at the beach. During the late spring and summer months the coast can get fogged in, but it's still beautiful. Just remember to bring a hoodie and you'll be a lot happier under the fog dome. Running the length of the Sunset and Richmond neighborhoods, there's plenty of space at Ocean Beach for the whole family.

Coast Trailhead
- Type: Place

The Coast trailhead is a popular place to start an easy hike, bike, or horseback ride to the beach. It meanders through creek-side habitat before going by wetlands as you approach the ocean. The trailhead is located along Laguna Road, approximately 15 minutes by car from the Bear Valley Visitor Center.
Fossil Brachiopods
- Type: Article

Brachiopods are one of the most common marine invertebrate fossils found in Paleozoic rocks in national parks. They were a dominant group of marine organisms during the Paleozoic, filling many of the ecological niches in Paleozoic oceans that bivalves have occupied since the end of Permian extinction, when most brachiopods became extinct.
Sculptured Beach
- Type: Place

Sculptured Beach is located two miles south of Limantour Beach, which is the closest place to park. Winter rains feed two creeks which stream across the sand into the ocean creating a wet barrier for beach walkers wishing to keep their feet dry. Once at Sculptured Beach, look for its namesake rocks lying on the shoreline. The sculpted rocks are exposed at low tide, along with the organisms that cling to them, creating an exciting area to go tidepooling.
