Gaan Point is the central unit of the War in the Pacific National Historical Park at Agat. The small promontory sits between the two halves of the invasion beach and was the strongest Japanese position on this stretch of coast — a concrete-reinforced bunker holding a 75mm gun that raked the attacking Marines as they crossed the reef in amphibious tractors. The gun, the bunker, and a Japanese light tank are preserved in place, with interpretive panels in English and Chamorro.
The site is small and can be walked in twenty minutes. It is set back from the road on a grassy headland with picnic shelters and a view both ways along Agat Bay. The reef at low tide is exposed almost to the line the Marines had to cross — useful for understanding the difficulty of the assault. There is no entry fee and a small visitor information point with toilets.
