What to Pack & Bring

Hawaii, USA

Layering for the Summit

Mauna Kea's summit experiences an alpine environment, regardless of the season at sea level. Layering your clothing is a requirement for staying warm and comfortable. Temperatures drop rapidly, and strong winds are a constant factor.

Essential Layers

  • Base Layer: Moisture-wicking material (merino wool or synthetics). Avoid cotton.
  • Insulating Mid-Layer: Fleece or down jacket for warmth. Easily packable and lightweight.
  • Outer Layer: Waterproof and windproof shell jacket for protection against extreme winds and light precipitation.

Head to Toe Protection

Body heat loss is significant through the head, and hands and feet are vulnerable to freezing temperatures.

Accessory Checklist

  • Headwear: A warm hat or beanie covers ears, guarding against significant heat loss.
  • Gloves: Warm gloves or mittens are a requirement, as hands become cold quickly in frigid, windy conditions.
  • Lower Body: Wear insulated hiking pants or warm base layers underneath sturdy pants. Avoid cotton jeans.

Footwear Recommendations

Summit Footwear

Insulated, waterproof hiking boots are highly recommended for summit visits, even if you only plan to view the observatories from nearby.

For cold, rocky terrain.

VIS Footwear

At the Mauna Kea VIS, closed-toe shoes suffice, but warm socks are a must.

Wool socks are ideal, warm even if damp.

General Big Island

Comfortable, versatile shoes for lower elevations and various activities.

Suitable for city walks and milder trails.

Essential Documents

Your Travel Papers

Careful preparation of your documents aids a smooth and stress-free trip to Mauna Kea and the Big Island.

  • Passport: Valid for at least six months beyond your planned departure date from the U.S.
  • Visa/ESTA: Proof of your approved ESTA or a valid U.S. Visa in your passport.
  • Travel Insurance: Carry both digital and printed copies of your policy details, including emergency contact numbers.
  • International Driving Permit (IDP): Recommended alongside your national driver's license for foreign drivers.
  • Vaccination/Health Records: Advisable, especially if you have pre-existing medical conditions or specific medications.
  • Doctor's Note: For prescription medications, notably controlled substances, to aid customs or security processes.
  • Reservation Copies: Printed and digital copies of all flights, accommodation, rental car, and tour bookings.
  • Emergency Contacts: A list of contacts at home and local emergency numbers (911 in the U.S.).

Technology & Electronics

Power & Connectivity

The U.S. Uses Type A and B sockets (two flat parallel pins or two flat parallel pins with a grounding pin), and the voltage is 120V at 60Hz. International travelers require an universal travel adapter. Ensure your devices are compatible with 120V or are dual-voltage.

Stay Connected

  • Universal Travel Adapter: For device charging.
  • Local Prepaid SIM Card: From providers like AT&T, T-Mobile, or Verizon for better coverage.
  • Portable Chargers & Power Banks: useful due to limited power access on Mauna Kea. A high-capacity power bank is suitable for long stargazing sessions.

Photography & Navigation

Capturing stunning night skies and landscapes calls for specific camera equipment. Navigation apps are useful for local services, weather, and road conditions.

Tools for Exploration

  • Camera Equipment: A camera capable of low-light performance is ideal for stargazing. A sturdy tripod is essential for long-exposure astrophotography.
  • Navigation Apps: Google Maps or Apple Maps are useful. Download offline maps for areas where cellular signal is unreliable, like parts of the Mauna Kea Summit Road.
  • Weather Apps: The Mauna Kea Weather Center app or website is useful for checking summit conditions.

Data Backup & Security

Cloud Storage

Use cloud storage services like Google Drive or Dropbox for photos and documents.

External Drive

Bring an external hard drive to back up precious memories and important information.

Device Safety

This safeguard deters data loss in case of device malfunction or theft.

Health & Wellness Items

First Aid & Medications

Your health is a priority, especially when visiting a high-altitude environment like Mauna Kea. A destination-specific first aid kit is advisable.

Kit Contents

  • Basic First Aid: Band-aids, antiseptic wipes, pain relievers (e.g., ibuprofen, acetaminophen), blister treatment, gauze, and medical tape.
  • Prescription Medications: Carry all in original labeled containers. A copy of the prescription and a doctor's note for controlled substances.
  • Over-the-Counter Medications: Antacids, anti-diarrhea medication, and motion sickness medication.

Environment Specific Needs

Addressing challenges unique to altitude and local conditions aids comfort. Sun protection and proper hydration are important.

Specialized Items

  • Portable Oxygen Canisters: Small, disposable canisters offer comfort for mild Acute Mountain Sickness (AMS) symptoms. Not a substitute for descent if symptoms worsen.
  • Rehydration Salts: Helpful for preventing dehydration at altitude.
  • Sun Protection: High-SPF reef-safe sunscreen, UV-protective lip balm, wide-brimmed hat, and sunglasses (preferably polarized).

Altitude & Motion Sickness

Altitude Sickness Remedies

  • Consult your doctor about prescription medication like Acetazolamide (Diamox) if you are especially susceptible to altitude sickness.
  • Begin taking medication as prescribed before your trip.
  • Small, portable oxygen canisters comfort individuals experiencing mild altitude effects.

Motion Sickness Remedies

  • For motion sickness on winding roads leading to Mauna Kea or elsewhere on the island.
  • Ginger chews offer relief.
  • Over-the-counter anti-nausea medications like Dramamine offer relief.
