Frequently Asked Questions

We recommend booking at least 2-3 weeks in advance, especially during peak season (December-March). Popular dates like new moon periods fill up quickly. However, we sometimes have last-minute availability, so feel free to check with us even for shorter notice.

We offer a full refund if you cancel at least 48 hours before your tour. Cancellations within 48 hours receive a 50% refund. We will also reschedule or refund your tour if weather conditions are unsafe, though light clouds rarely affect stargazing quality at our elevation.

The minimum age for summit tours is 13 years old. This is due to the extreme altitude (13,796ft) and the physical demands of cold temperatures and reduced oxygen. Lower-elevation stargazing options are available for families with younger children. The upper age limit for most summit tours is 75–80 years. All minors must be accompanied by an adult.

Most people handle the altitude well, but we ascend gradually and monitor all guests. Those with heart conditions, severe asthma, pregnant women, or anyone who has scuba dived within 24 hours should not join. We provide oxygen if needed and can descend quickly if anyone experiences altitude sickness symptoms.

Altitude sickness (acute mountain sickness, or AMS) typically feels like a persistent headache, often accompanied by nausea, dizziness, unusual fatigue, or shortness of breath during mild exertion. Many people experience a mild headache at 13,796 feet — this is normal and usually resolves quickly after descent. Serious symptoms to watch for include vomiting, loss of coordination, confusion, or chest tightness. If you feel any of these, tell your guide immediately. Do not try to push through serious symptoms. The good news: because our tours include a mandatory acclimatization stop at 9,200 feet, most guests arrive at the summit already adjusted and have no significant issues.

The single best preparation is to stay well hydrated in the 24 hours before your tour — dehydration worsens altitude symptoms significantly. Avoid alcohol the night before. Get a good night's sleep. On the day of the tour, eat a normal meal (not too heavy) before pickup. Avoid strenuous exercise the morning of your tour. If you have been scuba diving, wait at least 24 hours before ascending to altitude. Our itinerary already builds in a 30–60 minute acclimatization stop at 9,200 feet before the summit climb, which is the most effective single measure for preventing altitude sickness.

Acetazolamide (Diamox) is a prescription medication that can reduce the risk and severity of altitude sickness when taken starting 24 hours before ascent. If you know you are sensitive to altitude or have had issues before, speak with your doctor before your trip about whether this is appropriate for you. Over-the-counter pain relievers like ibuprofen can help manage headache symptoms at altitude. We do not dispense medications on tours, but our guides carry supplemental oxygen and are trained to recognize and respond to altitude sickness symptoms.

Your safety is always our first priority. If you or anyone in your group experiences significant altitude sickness symptoms, our guides will descend immediately to lower elevation — symptoms typically improve within minutes of descending even a few hundred feet. Our vehicles carry supplemental oxygen for guest use. No one is ever pressured to stay at altitude if they feel unwell. We would rather you have a comfortable evening at the Visitor Information Station (9,200 feet) than suffer through the summit experience. In the case of weather or health cancellation, we reschedule or refund your tour.

Summit temperatures typically range from 30-45°F, but can drop below freezing. Wind chill makes it feel even colder. We provide high-quality winter parkas and gloves for all guests. We recommend wearing layers, long pants, closed-toe shoes, and bringing a warm hat. Your comfort is important to us!

We monitor weather constantly and will contact you if conditions require rescheduling. Light clouds at lower elevations often clear above 10,000 feet. If we must cancel for safety or visibility, you receive a full refund or can reschedule. Your safety and experience quality are our top priorities.

This depends on the season and time, but typically includes planets (Saturn's rings, Jupiter's moons, Mars), deep sky objects (nebulae, star clusters, galaxies), and the moon if visible. Our guides use laser pointers to identify constellations and share stories of Hawaiian celestial navigation. Each tour is unique!

Absolutely not! Our tours are designed for all experience levels. Our guides are skilled at explaining concepts clearly whether you're a complete beginner or advanced amateur astronomer. We welcome questions and adapt our presentation to the group's interest level.

Yes! We encourage photos and our guides will help you capture images through the telescope using your smartphone or camera. Our astrophotography tour provides intensive instruction for those wanting to master night sky photography. Regular tours include basic photo assistance.

We offer hotel pickup for most Kona and Waikoloa resorts (check at booking). Otherwise, we meet at our staging area in Waimea. Exact location and timing are provided in your confirmation email. We recommend arriving 10 minutes early.

Bring a warm hat, wear closed-toe shoes and long pants, and layer your clothing. We provide parkas and gloves. Optional items: camera, small flashlight with red filter, personal snacks, and water. Avoid bringing anything valuable as conditions can be dusty. We provide what you need for comfort!

From Kona, it's approximately 90 minutes to the summit. We make the journey part of the experience, stopping at scenic points and gradually ascending to help with acclimatization. The drive itself offers spectacular views and photo opportunities.
