Mountain Tour Arrangements

Tours of the Mauna Loa Observatotry are performed by appointment only. Due to staffing issues at this time, tours are only available on specified Thursdays at 12:30 pm for the foreseeable future and should be requested at least 2 weeks in advance. We are hopeful that we will be able to open up more tour dates this coming spring and we apologize for the inconvenience. To schedule a tour, contact Aidan Colton by email or (808-933-6965 x233).

Office Tour Arrangements

The MLO office in Hilo is mainly administrative, but there is a small visitor center with displays of atmospheric research equipment and results. Guided office tours with hands-on displays can be arranged on selected weekdays. Office tours have been used in the past as activities for school groups and classes. To schedule a tour, contact Aidan Colton by email or phone (808-933-6965 x233). Please try to make your request a few weeks in advance.

Transportation Needs

Transportation is not provided for you to the mountain site, or to the MLO office, due to federal policy. All housing and transportation needs must be arranged on one's own.
