A section of Crater Rim Drive in Hawai'i Volcanoes National Park that was closed in 2008 for safety reasons has reopened to the public--but only for foot traffic. The route provides an easy walk that offers excellent views of some of the park's key features.
An upcoming solar eclipse may attract more attention, but some parks are also planning for visitors who would like to observe an even more unusual celestial event. The Venus Transit on June 5 will be a literal "last chance in your lifetime" occurrence.
If you're lucky enough to be in Hawaii next week, swing by Hawai'i Volcanoes National Park on Tuesday to learn about "natural" air pollution, the volcanic gases and other volcanic air pollution spewed from Kīlauea.
