Hawaii, a volcanic paradise, offers diverse hiking trails ranging from lush rainforests to rugged coastlines. Each island presents unique challenges and rewards, inviting adventurers to experience nature’s grandeur firsthand. This guide dives deep into some of the most scenic, unforgettable hikes Hawaii has to offer, providing insights and tips to help you conquer them safely and responsibly.
Diamond Head Summit Trail, O’ahu
Perhaps the most iconic hike on O’ahu, the Diamond Head Summit Trail is a moderate, paved path leading to a panoramic view of Waikiki and the Pacific Ocean. Don’t let the pavement fool you; the climb is a steady uphill ascent that will get your heart pumping. The trail is only 1.6 miles roundtrip, making it perfect for a morning adventure. Remember to bring water, as it can get hot, even early in the day.
- Cost: $5 per vehicle or $1 per pedestrian to enter Diamond Head State Monument.
- Directions: From Waikiki, take Kalakaua Avenue east, then turn onto Diamond Head Road. The entrance is well-marked. Plenty of parking is available, but it can fill up quickly, especially during peak season.
- Recommendations: Arrive early (before 8 AM) to avoid crowds and the heat. Wear sunscreen, a hat, and comfortable walking shoes. Take your time and enjoy the views along the way.
- Practical Example: My first time hiking Diamond Head, I underestimated the heat and ran out of water halfway up. Luckily, a friendly local shared some of theirs! Learn from my mistake and bring plenty.
Manoa Falls Trail, O’ahu
Immerse yourself in a true rainforest experience on the Manoa Falls Trail. This 1.6-mile roundtrip hike takes you through a dense, lush jungle to a stunning 150-foot waterfall. Be prepared for muddy conditions, especially after rain, which is common in this area. The trail can be slippery, so wear appropriate footwear with good traction. The humidity is also high, so pack plenty of water.
- Cost: Free, but parking may cost a few dollars at the nearby Lyon Arboretum.
- Directions: From Waikiki, take H-1 West, then exit onto Punahou Street. Turn onto Manoa Road and follow it until you reach the end. Parking is available near Lyon Arboretum, from which the trail is easily accessible.
- Recommendations: Wear hiking boots or shoes you don’t mind getting muddy. Bring mosquito repellent. Consider visiting after a period of dry weather to minimize the mud. Be aware that falling rocks are a potential hazard near the waterfall, so stay on the marked trail. According to the Hawaii Department of Land and Natural Resources, flash floods have been reported in the area. Do not attempt to cross flooded streams.
- Practical Example: On a recent hike, I saw several people wearing sandals struggling with the mud. Closed-toe shoes are definitely the way to go here!
Kalalau Trail, Kaua’i
The Kalalau Trail is legendary, offering breathtaking views of the Nā Pali Coast. This challenging 11-mile hike (one way) requires a permit for overnight camping and showcases Kauai’s raw beauty. Most hikers opt for the shorter day hike to Hanakapi’ai Falls (8 miles roundtrip), which is still a strenuous but rewarding experience. Be aware that the Hanakapi’ai stream crossing can be dangerous, especially after rain. According to the Hawaii Department of Land and Natural Resources, permits are required because of the trail’s high popularity and to protect the fragile environment.
- Cost: Permits are required for any portion of the Kalalau Trail beyond Hanakapi’ai Valley and cost varies. Parking reservations also are required
- Directions: Drive to the end of Highway 560 (Kuhio Highway) at Keʻe Beach. Parking is limited and permits are required, so plan accordingly. The trailhead is located at Keʻe Beach.
- Recommendations: Book your permits well in advance. Wear sturdy hiking boots and bring plenty of water and snacks. Check the weather forecast before you go and be prepared for rain. The stream crossing at Hanakapi’ai can be treacherous; if the water is high or flowing swiftly, do not attempt to cross.
- Practical Example: I met a hiker who wasn’t prepared for how difficult the Kalalau Trail is. He ran out of water and had to turn back early. Proper planning is crucial for this hike.
Waimea Canyon Trail, Kaua’i
Known as the “Grand Canyon of the Pacific,” Waimea Canyon offers several hiking trails with stunning views of the canyon’s colorful cliffs and deep valleys. The Canyon Trail to Waipo’o Falls is a moderate 3.6-mile roundtrip hike that leads to a lookout point with a magnificent view of Waipo’o Falls. The Kukui Trail is a much more challenging option, descending 2,000 feet into the canyon. This is a steep and strenuous hike, and is currently closed due to severe damage from flooding and landslides. The Hawaii Department of Land and Natural Resources website should be checked for current trail status and safety alerts.
- Cost: Entrance to Waimea Canyon State Park is free.
- Directions: Take Highway 550 (Waimea Canyon Drive) from Kekaha. The Canyon Trail and Kukui Trail are both located along this road.
- Recommendations: Wear sturdy hiking shoes as the trails can be rocky and uneven. Bring water and sunscreen. Check the weather forecast before you go, as the canyon can be prone to fog and rain.
- Practical Example: I’ve hiked the Canyon Trail several times, and the views are always breathtaking, especially at sunset when the canyon walls are bathed in golden light. Bring your camera!
Haleakalā Sliding Sands Trail, Maui
Step into another world with a hike inside the Haleakalā Crater. The Sliding Sands Trail is a challenging but rewarding hike that takes you down into the heart of the volcano’s massive crater. The landscape is surreal, with cinder cones, volcanic rock, and unique plant life. Be prepared for significant elevation changes and fluctuating temperatures. The air is thin at this altitude, so take it slow and drink plenty of water.
- Cost: $30 per vehicle to enter Haleakalā National Park, or $25 per motorcycle.
- Directions: Drive to the summit of Haleakalā National Park. The Sliding Sands Trailhead is located near the visitor center.

- Practical Example: I was surprised by how much the temperature dropped once I started descending into the crater. Layers are essential for this hike.
Pipiwai Trail, Maui
Located within Haleakalā National Park (but on the coast), the Pipiwai Trail is a magical 4-mile roundtrip hike that takes you through a bamboo forest to the stunning Waimoku Falls. This trail is relatively easy, with a gradual elevation gain. The highlight is undoubtedly the bamboo forest, where towering bamboo stalks sway in the breeze creating an enchanting atmosphere. Be prepared for muddy conditions, especially after rain.

The trail is only about 0.6 miles roundtrip, but the steep descent and ascent can be challenging for some.

This 3.3-mile loop trail descends into the Kīlauea Iki crater, crossing the solidified lava lake floor before ascending back up through a lush rainforest.

FAQ Section
What is the best time of year to hike in Hawaii?
The best time to hike in Hawaii is generally during the dry season, which runs from April to September. However, Hawaii is a tropical climate, so rain is possible any time of year.

Are hiking permits required in Hawaii?
Permits are required for some hikes in Hawaii, particularly for overnight camping and for access to certain areas. The most well-known example is the Kalalau Trail on Kauai. Check with the appropriate land management agency (e.g., the Hawaii Department of Land and Natural Resources or the National Park Service) to determine if a permit is required for the hike you are planning.
What are the most challenging hikes in Hawaii?
Some of the most challenging hikes in Hawaii include the Kalalau Trail on Kauai, the Kukui Trail in Waimea Canyon (currently closed), the Sliding Sands Trail in Haleakalā National Park, and the Pelekunu Trail on Molokai (which requires guided permission).

Are there any dangerous animals in Hawaii that hikers should be aware of?
Hawaii is generally considered a safe place to hike in terms of dangerous animals. There are no native land mammals that pose a threat to humans. However, there are a few things to be aware of.

Wild pigs can be encountered in some areas, although they are generally shy and will avoid humans. The most significant animal-related danger comes from marine life, particularly if hiking near the coast. Never turn your back to the see and be aware of strong currents.
