Hawaii Volcanoes National Park, Hawaii – The National Park Service turns 97 on Sunday and so there will be no charge to enter any of the 401 national parks in America, including Hawai‘i Volcanoes National Park.

HVNP issued a media release inviting the public to Kilauea:

With more than 150 miles of hiking trails, and 520 square miles that stretch from sea level to the 13,677-foot summit of Mauna Loa, the opportunity to enjoy Hawai‘i’s natural splendor abounds in Hawai‘i Volcanoes National Park. A schedule of free ranger-led programs and guided hikes is posted daily outside Kīlauea Visitor Center by 9:30 a.m. Visitors can enjoy programs including Explore the Summit – a one-hour walk from the Kīlauea Visitor Center to the edge of Kīlauea caldera, and Life on the Edge, a 20-minute talk about the current eruption from Halema‘uma‘u Crater given daily at Jaggar Museum overlook.

To further entice visitors, the Volcano Art Center says it is extending a special gift to its patrons:

Take advantage of free park entrance on Sunday and an extra 5% off all purchases over $97 at the VAC Gallery, located next to the Kilauea Visitor Center in Hawaii Volcanoes National Park. The gallery is open from 9:00am to 6:00pm every day, but this festive promotion is only available on Sunday.

Volcano Art Center is a nonprofit 501(c)(3) organization founded in 1974 to “develop, promote and perpetuate the artistic, cultural and environmental heritage of Hawaii’s people through the arts and education.”

The park service says two other fee-charging parks in Hawaii – Pu‘uhonua o Hōnaunau National Historical Park and Haleakalā National Park on Maui – will also waive entrance fees on August 25.

And if you miss this weekend, you will have another chance for a free visit. There will be more free-entry days in 2013: September 28 is National Public Lands Day, the largest single-day volunteer effort for public
