Guam's warm climate, sandy beaches, and turquoise waters beckon visitors to rediscover the island's rich heritage.
Fishing, hiking, picnicking, and (for those with experience) snorkeling and diving are among the many recreational opportunities available in the individual park units and around the island.
The year-round temperature averages 27°C (80°F) and the ocean temperature a pleasant 27.2°C (81°F) May to November is the rainy season, and you can expect wet, hot, and humid days. Temperatures cool down from November through April, the dry season, and tropical trade winds are common. Typhoons can occur in any month, although they are more common during the rainy season. But don't worry: typhoons give ample warning of their coming and there is plenty of time to take shelter.
Park historic structures and military equipment are more than 50 years old and are very fragile. Do not disturb any of the historic ground features, such as foxholes, trenches, and bomb craters.
Please do not remove or mar the historic and natural objects beneath the water's surface. They are protected by law.
