    Tour participants

  • How many people can I bring on a tour?
    The smaller your group, the greater the likelihood that we can accommodate you. Six or fewer are ideal numbers.

  • I have more than 6 people. Can I still get a tour?
    Yes, we can accommodate up to 10 people on a non-sunset tour without additional restrictions.

  • What are the restrictions on having more than 10 people?
    The Office of Mauna Kea Management (OMKM) requires a permit for any group of more than 10 people. If your group is more than 10 people you must submit a request and receive approval for your visit.

    If you receive approval from OMKM you may bring up to 12 people to Gemini if your tour is approved by Gemini. This number includes everyone –– chaperones, drivers, translators, etc.

  • I have more than 12 people. Can I still arrange for a tour?
    Provided you have received approval from the Office of Mauna Kea Management, it might be possible to have a larger tour with special arrangements. However, this can often present significant logistical hurdles, including safety, staffing, and scheduling that require more lead time.

    To ensure full consideration for large tours, requests should be made AT LEAST one month in advance of your expected tour date.

  • Who can go on a Gemini Tour?
    Anyone in good health aged 18 or older (16 & 17 with a signed waiver)
    No one who is pregnant
    No one who has been scuba diving within 24 hours of the tour.

  • I have a medical condition. Is it safe for me to travel to the summit?
    All travel to an elevation above 9,000 feet should be cleared with your medical professional BEFORE coming to the summit.

    Health issues of particular concern:
    Pulmonary (heart issues) –– It is NOT recommended that you go to the summit area
    Respiratory (breathing issues) –– Check with your doctor and inform your tour guide
    Diabietes (blood sugar issues) –– Check with your doctor and monitor yourself closely.

    Anyone experiencing fainting, vertigo, or currently experiencing the effects of a cold, flu, or allergies, etc. should NOT GO to the summit.

  • Are minors allowed?
    Only those of ages 16 & 17, each with an additional signed waiver from their legal parent or guardian.

  • Can my 15 year old come if he or she is really close to their birthday/ or have a doctor’s permission?
    Unfortunately not. This is the universal policy for the entire summit area of Mauna Kea –– not just Gemini.Everyone must be at least 16 by the day the tour is to take place. No exceptions.

    Tour schedule

  • How much time does a typical tour take?
    A typical tour takes 45 minutes to an hour at the telescope facility. However, you should plan on at least 6 hours from start to finish with travel time, acclimatization, etc.

  • What is a typical schedule like?
    Assuming Hilo is your point of departure (please allow additional time if coming from other locations):

    10:30 Get Gas (there are no gas stations once you leave town)
    11:00 Depart Hilo
    12:00 Arrive at Hale Pohaku (HP) (lunch if prearranged)/Visitors Information Station(VIS)
    12:45 Safety briefing at HP or VIS
    1:00 Departure for summit
    1:30 Arrive at Gemini
    2:30 End of Tour/ on your own.

  • Is it possible to arrange a tour at other times?
    Yes, with additional permissions and advance lead time, it is possible to arrange a tour between 10:30am and 3:30pm.
    In addition to the tour, remember that 2.5+ hours of travel and acclimatization is necessary before the tour begins.

  • Can I arrange a visit on a Monday or a Friday (or days before and after a holiday)?
    Yes, however, we have limited staff on these days, so we restrict the number of visitors to the telescope.

  • Can I get a tour on a weekend or holiday?
    Generally this is not possible. Due to safety issues, we must always have two staff members present to accompany anyone (or a group) at our summit facilities. Under special circumstances (and with plenty of lead time) we can sometimes make exceptions.

  • Can I visit the telescope at night?
    Evening tours are not granted without special permission from our nighttime operations staff and are very limited in capacity.

    Transportation

    *****Important: You must provide your own transportation for all tours.*****


  • Can I get a ride from the Visitors Station, or Hale Pohaku to the summit area?
    Unfortunately, Gemini uses government vehicles, and we are not allowed to provide transportation to non-Gemini staff.

  • I don't have a 4x4 vehicle. Can I drive up without one?
    This is NOT recommended. The access road, while well maintained, is a very steep dirt road, and can be difficult for a vehicle that does not have a low gear ratio and good traction, especially on the way down. Also, many cars that are not equipped to handle altitude get stuck and must be towed down at significant danger and expense.

  • Where can I rent a 4x4 drive vehicle?
    Most rental companies have restrictions about taking their cars to the summit of Mauna Kea. You should check with your rental company.

  • Is the road dangerous to drive?
    As with any mountain road there are inherent hazards that should be taken into account. The road is well maintained and graded twice a week.

    Potential hazards include:

  • narrow, rough surface
  • hairpin switchbacks
  • ice or black ice
  • high winds
  • low visibility due to fog and/or low sun angle
  • steep grades (use low gear when descending)
  • maintenance vehicles (or other slow moving trucks)

  • Is there anywhere to get gas on Mauna Kea or on the way to Mauna Kea?
    Fuel is not available on the mountain (or on Saddle Road) visitors will need to fill up before leaving their destinations.

    Visiting Mauna Kea

  • • What should I expect while at the summit area?
    There is a wealth of information at the Visitor Information Station (VIS) website. Please take some time to fully explore the site.

  • What are the safety hazards/concerns?
    Gemini addresses major safety issues in a comprehensive safety guide & waiver and briefing that is given to all visitors to the Gemini facilities on Mauna Kea. Additional information can be found here.

  • I don't have the Gemini waiver yet. Is there something else I can read?
    Yes, the following two documents will provide some basic information: VIS "Hazards" flyer, p.1 | VIS "Hazards" flyer, p.2

  • Is there a video I can watch that will tell me about the hazards?
    Yes, the VIS has produced this informative 8-minute video.

  • What's the weather like on the mountain. How will I know if the road will be open?
    Your tour-guide\host will be able to tell you the current conditions at the summit area, and you can also check on the forecast, current conditions, and current web cam views.

  • I need to get a permit from the Office of Mauna Kea Management. Where can I get one?
    There are two types of permits. Please click on the appropriate link for your group.
    Film & Media permits
    Group permit form for more than 10 people

  • Where is the nearest gas station?
    Hilo or Waimea (Kamuela)

  • Where are the nearest medical facilities?
    In Hilo, at least 1.5 hours from the summit.

  • Where is the nearest store?
    There is a gift shop at the VIS where water and some snacks may be purchased.

  • Are there restroom facilities available?
    There are facilities at the VIS, and Hale Pohaku. There are also portable potties on the summit area if you are not on a facility tour.

  • Are there any restaurants on the mountain?
    There are picnic tables at the VIS (and limited food for purchase), but no public dinning facilities.

  • Are there meal options for Gemini facility tours?
    Meals are available for purchase but must be requested before your tour. (see meal option section)
    Back to Top

    What to bring?

  • What should I bring?
    It's a 6+ hour trip to a remote mountain location, with little in the way of creature comforts or supplies (like gas), or medical help (which is over an hour away). Plan accordingly. A list of things to consider follows:

    ***Close-Toed Shoes are required***
    Sun protection – hat, sunglasses, lip balm, sunblock
    Winter gear – hat, gloves, heavy jacket, boots
    Safetywater, snacks, required medications, flashlight (nighttime visitors)

  • It's Hawai‘i, come on, do I really need to bring cold weather gear?
    Yes, temperatures at the summit are, on average, 35˚ F colder than at sea leavel. Even if the daytime weather is ideal, it can change rapidly. In addition, the inside of the dome is kept at the expected night time temperature (generally freezing). Those taking sunset tours will be particularly susceptible to the cold.

  • We have a large group (more than 6), should I bring an extra vehicle?
    It is HIGHLY recommended that you have at least one extra vehicle in case someone in your group gets altitude sickness and needs to be taken to a lower elevation. This way the rest of your group will not need to leave as well.

    Meal options

  • Can I get meals at the summit?
    There are no meal options at the summit for visitors.

  • Where are meals served?
    Official visits can arrange for meals at the Hale Pohaku (HP) facility located a short drive above the VIS.

  • How much are HP meals?
    Currently, lunch is $11.50, and dinner is $19.00 (subject to change).

  • What forms of payment does Gemini accept? When do I need to pay?
    Please make all payments at the time of your visit with either a check made out to the Gemini Observatory or cash in the exact amount (your tour guide will not be able to make change).

  • Are there vegetarian, vegan, etc. meal options?
    Yes, however, these requests need to be made at least a week in advance.

  • What is the food like?
    It is cafeteria style, usually with two entre options, and sometimes a salad (or even soup). There are also help yourself ice-cream and soda fountains.

  • Can we eat at a different time?
    Breakfast is served from 6:00 - 8:00am
    Lunch is served from 12:00 - 1:00pm
    Dinner is served from 4:30 - 6:00pm
    Any changes to this schedule require significant logistical hurdles, and will not be changed without sufficient reason, and forewarning.

  • Can I bring my own food to Hale Pohaku to eat?
    This would be like bringing your own food into a restaurant. Please consume outside food at the VIS, not in the dinning area of HP.

  • If I just want a cup of coffee, or snack, will Gemini be charged?
    Anything consumed at HP must be accounted for. A beverage, for instance, is considered part of a meal, but if you get a beverage by itself, it is counted as a small snack and should be noted on the snacks form provided at HP and Gemini will be charged.

  • I work for Gemini and want meals for my myself and my guests. How does that work?
    Any staff member acting as an official tour guide may request a meal for themselves paid for by Gemini. All other meals (for non Gemini staff or non-official tours) must be reimbursed to Gemini the same week as the tour.

    Sunset tours (aka twilight tours)

    Sunset Tours are only considered on special case by case basis. There are NO "Piggy Back" sunset tours.
  • What is a sunset tour?
    These tours take place prior to sunset and continue into the twilight when nighttime operations are just getting underway. They are very limited in availability.

  • How many people can go on a sunset tour?
    Sunset tours are limited to a maximum of 6 guests plus the staff tour guide.

  • What is a typical sunset tour schedule?
    Most tours depart from Hilo [mid-afternoon] and arrive at the summit usually about an hour before sunset when we meet up with the night crew. Note: Exact departure times will vary throughout the year. Please refer to travel times for planning your trip.

  • I’m staff and have a scheduled shift at the summit. Can I bring someone as a guest for a sunset tour?
    No, however, you may invite someone as a guest as long as another staff member, not involved in that night's operations, serves as their host while you are working.

  • As a staff member leading a tour, do I have to wait for the night crew to arrive before we enter the building, what if someone needs to use the restroom?
    We have a two person rule at Gemini, for practical reasons that means that you may not enter the summit facility unless there are also day crew present or the night crew has arrived. If you need to use the restroom and no one else is at the facility you must use the porta-potties.

  • Can my request for a sunset tour be rejected?
    There are any number of reasons your tour may have been rejected:

    too many people in your group
    a tour is already scheduled for that day or time
    it is during a classical observing or priority visitor run
    it is during a training shift
    it is during an engineering shutdown
    observations that evening are especially complex.

  • If my request for a sunset tour is rejected, what should I do?
    Depending on the reason for the rejection, you might try again with fewer people, on a different night, request a daytime tour, or try one of the alternate public tour options.
