Visitors to the park should expect changeable weather. Kilauea's summit, at 4,000 feet above sea level, can be rainy and chilly any time of the year. The coastal area is usually warm and dry. Come prepared. Bring a windbreaker or rain jacket, long pants, and closed-toe shoes.
The Jaggar Museum, located adjacent to the Hawaii Volcano Observatory, opened in 1987. The museum is the fulfillment of a dream of Dr. Thomas Augustus Jaggar, a scientist who adopted the Kilauea region as his home in 1912 and devoted his life to the study of volcanoes. As early as 1916, he proposed creating a museum to help visitors understand how volcanoes work. Today, more than a million and a half visitors a year tour the museum and learn about volcanoes through colorful and informative displays.
