Frequently Asked Questions
When can I fly or drive to altitude?
For single dives a minimum surface interval of 12 hours is suggested before flying. If you have been doing multiple days of multiple dives, PADI recommends a minimum surface interval of 18 to 24 hours. We also strongly recommend that you do not plan to drive to the volcano, Waimea or Hilo, take a helicopter tour or stargaze on the top of Mauna Kea the same day that you dive. Following these recommendations reduces DCS risk but does not guarantee that a diver will avoid DCS.
