What to expect on Kīlauea Iki West Overlook – Kīlauea Iki Crater Trail loop from Kīlauea Iki

This trail offers an incredible contrast, starting with a descent through a lush rainforest teeming with native Hawaiian plants before opening up to the vast, otherworldly expanse of the solidified lava lake. You'll navigate steep and rocky sections on the way down and up, with the crater floor itself presenting uneven, unstable, and sometimes razor-sharp lava terrain. Keep an eye out for steam rising from cracks in the ground, a vivid reminder of the geological activity beneath, and peer into the vent below the Puʻu Puaʻi cinder cone that erupted to 1900 feet in 1959. This moderate to challenging route is a workout, but the constantly changing scenery makes it incredibly rewarding.

Planning your visit

The Kīlauea Iki West Overlook parking area is your starting point for this loop. To make the ascent out of the crater feel less strenuous, many recommend hiking the loop clockwise. Be prepared for varying weather conditions; the exposed crater floor can get very warm, even on cloudy days, as the lava stores heat. Sturdy footwear is essential for the uneven terrain, and hiking poles are a good idea if you have knee issues or prefer extra stability.
