Hawai‘i Volcanos National Park on the Big Island said its main unit will remain open to visitors on Wednesday, but that it will not collect fees on the designated National Day of Mourning in honor of the death of George H.W. Bush, the nation’s 41st president.

On Maui, Haleakala National Park also announced plans to waive entrance fees on Wednesday in honor of Bush. Haleakala said its visitor centers, campgrounds, and restrooms will remain open on Wednesday. Sunrise viewing at the summit will also be open, but reservations are required.

Bush died Friday at his home in Houston at age 94. He will lie in state at the Capitol rotunda in Washington today and Wednesday before his burial Thursday in Texas.

By executive order, Wednesday has been designated a National Day of Mourning, and most federal offices will be closed.

The park’s Kahuku unit will be closed, as well as its post office. Flags will also be flown at half-staff at the park until Dec. 30.
