Preparing for Your Climb on Koko Head Crater

The Koko Head Crater Trail, also known as the Railroad Hike in Oahu, is a tough but rewarding adventure. With over 1,048 old rail ties or steps to conquer, preparation is key. Let's talk about how you can gear up and conquer this exciting journey.

Since the trail is challenging, you'll need sturdy hiking shoes with good grip and support. Don't forget to bring a light backpack with water bottles (stay hydrated), sunscreen (Hawaiian sun is intense), snacks for energy, and maybe a walking stick for balance.

Dress comfortably with lightweight clothing that allows easy movement. Opt for breathable fabrics because Hawaii's climate is tropical. Don a head covering and shades to protect from the sun's rays, especially during midday treks when it is most intense.
