Kao Rha is the tallest peak on Koh Phangan. It takes about 1.5 hours to climb up and 1 hour to walk down. On top there’s an amazing view to the North and North East of the island. The hike to Bottle Beach is another good one! Start the hike at Had Khom and climb over the mountain to Bottle Beach where you can walk up to another further view point! This hike is a little easier than Koh Rha, and takes about 1 hour. You can either hike back to Had Khom for take a little long tail boat back.
