The History of Koko Crater Trail
Koko Crater, or Kohelepelepe in Hawaiian, is an ancient tuff cone formed by volcanic activity thousands of years ago. While it may no longer be an active volcano, it plays host to one of Oahu’s most iconic hiking trails. The trail itself was once a railway built during World War II, designed to transport military supplies and personnel to a lookout at the summit. Today, the remnants of this old railway serve as the path for hikers, providing a steep and exhilarating climb up more than 1,000 railroad ties acting as steps to the top.
The Hike: What to Expect
The Koko Crater Hike is often referred to as one of Oahu’s most physically demanding hikes, despite being only about 1.5 miles (2.4 kilometers) round trip. What makes it so challenging is the relentless incline, with an elevation gain of around 1,200 feet (366 meters) in just 0.7 miles. The trail consists of uneven railroad ties, some of which are spaced far apart or precariously positioned. There is even a bridge section where the ties are elevated off the ground, requiring hikers to carefully balance across the wooden planks.
Despite its difficulty, the hike attracts adventurers of all skill levels who are eager to conquer the ascent. The key is to go at your own pace, take breaks when needed, and remain hydrated, especially under Hawaii’s tropical sun.
The Reward: Panoramic Views
Reaching the summit of Koko Crater is a triumphant moment for every hiker. At the top, you'll be greeted by a panoramic view of the surrounding coastline and beyond. To the east, you’ll see Hanauma Bay, one of the island’s premier snorkeling spots, with its coral reefs clearly visible from the height. To the north, you can take in Diamond Head in the distance, another popular volcanic crater and hiking destination. On clear days, the views extend to the deep blue waters of the Pacific Ocean, the lush green landscapes of Oahu, and even parts of Honolulu.
Additionally, the summit is home to the remains of old military bunkers, providing a glimpse into the island's historical role during World War II.
Preparation and Tips for the Koko Crater Hike
Given its steep and challenging nature, proper preparation is essential for a safe and enjoyable experience on the Koko Crater Hike. Here are some tips to help you prepare:
- Wear Proper Footwear: Sturdy shoes with good grip are essential for navigating the uneven and sometimes slippery railway ties.
- Hydrate: Bring plenty of water, as the trail is exposed to the sun with little shade. The Hawaiian heat can be intense, especially around midday.
- Sun Protection: Wear sunscreen, a hat, and sunglasses to protect yourself from the strong UV rays. Consider starting your hike early in the morning to avoid the hottest part of the day.
- Pacing: The trail is steep and demanding, so it’s important to pace yourself and take breaks as needed. There are several places along the trail where you can step aside and rest.
- Safety on the Bridge: If you’re uncomfortable with heights, consider taking the bypass trail around the bridge section. The elevated section can be intimidating for some, though it is stable.
- Timing: To beat the crowds and the heat, try to start your hike early in the morning or later in the afternoon. Sunrise and sunset hikes are particularly popular for the stunning views.
