I have an issue with altitude, is it ok that I go?

This tour does not go all the way up to the summit of Mauna Kea, so your issues with altitude will be much less. We only go up to about 7000ʻ with the summit at 13,000. We encourage guests to be properly hydrated which reduces altititude sickness. Consult with your doctor before doing any activities you may be unsure of. 1. Big Island Stargazing On Mauna Kea
