Success on Mauna Loa starts with good planning. This isn't a hike you can decide to do on a whim. Every detail matters at this altitude and in this environment.
You need two permits for the ʻĀinapō Trail summit route. Start the permit process weeks ahead. Popular dates fill up fast.
Permits and Paperwork
First, contact the Hawaii Department of Land and Natural Resources. They manage the lower trail and Halewai cabin. You can apply online or by phone. They'll give you a gate code for the ranch road.
Second, get a permit from Hawaii Volcanoes National Park. They control the summit cabin and upper mountain. Their permit system is separate. You need both permits to complete the full hike.
Hawaii DLNR Permit
- Lower trail & Halewai cabin access
- Kapāpala Ranch gate code provided
- Apply 2-4 weeks in advance
- Online or phone application
Hawaii Volcanoes NP Permit
- Summit cabin & upper mountain
- Separate permit system
- Required for true summit access
- Book as early as possible
Dealing with Altitude
Altitude sickness is real and dangerous. At 13,000+ feet, there's about 40% less oxygen than at sea level. Your body needs time to adjust.
Plan to spend time at higher elevations before your hike. Visit Mauna Kea or the Mauna Loa Observatory a few days early. Even better, spend a night camping at elevation. Your body will start making more red blood cells.
Altitude Acclimatization Timeline
During the hike, watch for symptoms. Headaches, nausea, and fatigue are early signs. If symptoms get worse, you must go down. No summit is worth your health.

Finding Gear on the Big Island
Most hikers bring their own gear. Outdoor gear rental is limited on the Big Island. Check sporting goods stores in Hilo and Kona. Some rent basic items like trekking poles or daypacks.
For specialized gear like mountaineering boots or sleeping bags, plan to bring your own. Many visitors ship gear ahead to their hotel. This ensures you have what you need.
