Guam’s ancient history and rich cultural heritage are memorialised at 118 sites listed on the US Register of Historical Sites and 155 on the Guam Register. A number of sites of interest relate to Chamorro culture and legends and others to historical events, which are scattered throughout the island.
 Fort Nuestra Senora de la Soledad
Nuestra Senora de la Soledad was one of the last forts built by the Spanish in support of the 19th century Galleon trade. From its cliff-top location, there is a commanding view of the Bay. In 1995, the fort was restored and its cannon still points out over the Pacific Ocean, at the spot where Magellan made his historic landing in 1521.
 Fort Santa Agueda
Fort Santa Agueda was built in 1800, overlooking the city of Hagatna and its bay. The fort’s cannon protected Hagatna harbour and the lucrative Galleon trade until the 1898 when an American frigate attacked the harbour during the Spanish-American War. The old Spanish cannon still points out over Hagatna Bay from the remnants of Fort Santo Agueda.
 Japanese WWII Landmarks
For those interested in WWII history, there are many WWII Japanese gun emplacements and caves, as well as sunken ships and airplanes in the clear ocean waters surrounding Guam. At Gann Point, the camouflaged gun emplacements are connected by tunnels, which were impregnable from the sea, but eventually destroyed by American tanks approaching from land. The Japanese also constructed an extensive system of tunnels in the Hagatna area, and today entrances to the caves, such as the one in Latte Stone Park, can still be seen. A captured Japanese mini-submarine that had been sunk outside Apra Harbor is now on display at the Navy Military Museum in Sumay Cove.
 Latte Stone Park
Latte stones are the pillars which provided the support to ancient Chamorro houses built as early as 500 AD. They are unique to the Marianas and comprise two pieces: a halagi, or supporting column made from coral limestone; and a capstone, known as a tasa, made from coral heads. The bones and important possessions of the ancient Chamorros were buried beneath the stones and remain untouched. Many Latte sites can still be seen in the north of the island.
Plaza de Espana
The Plaza de Espana, which is located in the centre of Hagatna, contained the palace of the Governors during Spanish rule. Although most of the palace was destroyed when Hagatna was bombed during WWII, there are still three structures standing, including the three-arched gate to Almacen, the Azotea and the Chocolate House.
 Tailafak Bridge
Tailafak Bridge, one of the countless small bridges that were built along El Camio Real (the old Spanish coastal road connecting Hagatna and Umatac) is one of the few remaining examples of Spanish architecture still in its original location. The bridge was constructed in 1785 and can be seen just off Route 2, south of the Agat Marina and Nimitz Beach Park.
 Two Lovers Point
Two Lovers Point Park marks the site where two star-crossed lovers plunged to their deaths several centuries ago. The daughter of a wealthy Spanish aristocrat and a young Chamorro man had fallen in love but were forbidden to marry. They decided that they would rather die than live apart and fled to this point where they were trapped by soldiers. The two lovers tied their hair together and jumped from the cliff. Today, you’ll find an observation platform on the cliff, from where you will find have breathtaking views of Tumon Bay.
War in the Pacific National Historic Park
The War in the Pacific National Historical Park was established in 1978, commemorating the sacrifice of the soldiers who participated in the WWII Pacific Theatre campaigns and also to conserve and highlight the outstanding historic, natural and scenic heritage of Guam. Asan Beach is one of the Park’s six units and was a main landing area used by the Americans in 1944 to recapture Guam from the Japanese. The other units include Asan Village, Alifan, Mount Chacho, Piti and Gann Point in Agat. You can still see Japanese costal guns, pillboxes and caves at these sites. The Park’s visitor centre and museum are located just north of Asan Beach.
Top Things to Do
 Cycle to Tarzan Falls
Guam’s interior is quite beautiful and among its most stunning features are the Tarzan Falls, known as kanuon in the native Chamorro language. The falls are a series of cascading drops, each ranging from 8-50 feet high, ending with a deep and clear pool at the base which is ideal for swimming. This particular destination is a favourite of off-trail hikers, known locally as boonie stompers. The falls are best reached from the village of Malojoj in Inarajan.
 Dive among the richest wrecks in the world
Many divers head immediately to the popular sites of Palau and Truk, but those in the know appreciate that Guam has plenty to offer in underwater exploration. In fact, no less than five shipwrecks are found off the island’s shores. The Spanish Galleon Neustra Senora del Pilar is at the top of the list for intrepid divers, as it is considered one of the world’s ten richest wrecks. Additionally, Guam’s waters are also home to the twin wrecks of the Japanese fighter Tokai Maru and the German gunboat Comoran. Other popular wrecks include a WWII Japanese Zero, a US tanker and also a large passenger liner.
For easy-access diving, there are numerous walk-in reef dives and a number of boat dive sites offering lots to see within a 10-20 minute ride from the shore. Located at the edge of the Marianas Trench, the deepest in the world, Guam boasts vivid turquoise lagoons and clear water, with visibility as far as 150 feet in December through until May. Various marine preserves have been established to protect undersea life.
Go for a stomp in the boonies
The Guam boonies comprise vast areas of undeveloped jungle and virgin beachfront, and boonie stomping involves hiking through these natural wonders. It’s a popular, though somewhat physically demanding pastime, enjoyed by residents and tourists. Guam's Department of Parks and Recreation offers public boonie stomps on Saturdays to different parts of the island.
Observe underwater life at Fish Eye Park
Fish Eye Park is an underwater observatory, descending into a WWII bomb hole that is located off the beach at Piti. When Guam was shelled during WWII, a number of bombs landed between the shoreline and coral reef surrounding the village of Piti. Today you can see the abundance of coral and marine life in one of these craters which has been designated a marine preserve. The Fish Eye Park observatory extends 31 feet below the surface of the ocean and visitors walk down into the air-conditioned observation chamber, which provides a 360° view of coral and marine life.
 Take a submarine to Atlantis
You can explore Guam's tropical reefs and enjoy its variety of marine life up close and not get wet. Underwater tours are offered by Atlantis Adventures aboard an air-conditioned 65-foot submarine, with a capacity of 48 passengers. Tours begin with a 15-minute boat ride from the dock at Aqua Marine World in Piti to the dive site just in Apra Harbor, followed by a 45-minute dive. Tour guides speak English as well as Japanese.
Take in a Greyhound race
Greyhound racing is a popular pastime on Guam for visitors and residents and the Greyhound Park in Tamuning features races on Tuesday through until Sunday. Gates open at 19:00, with races starting at 19:45. Betting is legal and payoffs can be sizeable.
