From challenging volcanic climbs across stark lava fields to gentle rainforest strolls past cascading waterfalls, the Hawaiian Islands offer a stunning array of trails for every skill level. This guide dives into some of the most rewarding hikes across the islands, covering everything from permit information and trail conditions to what to pack and expect along the way.
Big Island Adventures: A Symphony of Fire and Flora
The Big Island, also known as Hawai’i Island, is a land of extremes. Here, you can hike across solidified lava flows, explore lush rainforests, and even summit a dormant volcano. The diversity is staggering, and the hiking opportunities are equally impressive.

Frequently Asked Questions
What is the best time of year to hike in Hawaii?
The best time to hike in Hawaii is during the shoulder seasons, spring (April-May) and fall (September-October). The weather is generally mild and dry during these months, and the crowds are smaller than during the summer and winter holidays. However, Hawaii’s climate is relatively consistent year-round, so hiking is possible any time of year.
Do I need a permit to hike in Hawaii?
Permits are required for some hikes in Hawaii, particularly in state parks and national parks. Check the specific regulations for the trail you are planning to hike. The Kalalau Trail, for example, requires a permit for both day hikes and overnight camping. Diamond Head and Iao Valley now require reservations for all visitors.
Are there any dangerous animals in Hawaii?
Hawaii is relatively free of dangerous land animals, but there are a few things to be aware of. Wild pigs can be aggressive, so avoid approaching them. Centipedes and scorpions can deliver a painful sting, so be cautious when hiking in rocky areas. Sharks are present in Hawaiian waters, but attacks are rare. Always swim in designated areas and follow the advice of lifeguards.
What should I do if I encounter a dangerous situation while hiking?
If you encounter a dangerous situation while hiking, such as a flash flood or a wild animal, remain calm and assess the situation. If possible, move to a safe location and call for help. Cell phone reception can be spotty in some areas, so a satellite phone or personal locator beacon (PLB) may be useful in remote areas.
How can I protect myself from the sun while hiking?
The Hawaiian sun can be intense, so it’s important to protect yourself from sunburn and heatstroke. Wear sunscreen, a hat, and sunglasses. Drink plenty of water and take breaks in the shade. Avoid hiking during the hottest part of the day (10 am to 2 pm).
What is leptospirosis and how can I prevent it?
Leptospirosis is a bacterial infection that can be contracted from contaminated water, soil, or animal urine. It is a risk in Hawaii, especially in areas with freshwater streams and waterfalls. To prevent leptospirosis, avoid drinking the water or swimming in pools, especially if you have any open cuts or sores. Always wash your hands after being around water or soil.
