I enjoyed the hike but I was prepared for the heat and carrying a lot of water. The mountain isn't too high, takes over 3h to come up but the sun gets tiring quickly so better leave as early as you can to avoid it, especially if you visit in hot season.
It's like a little maze, it would've been a bit difficult without a guide as you have to crawl in some spots and there are extra corridors. It isn't huge enough to actually get lost but when you loose track and imagination starts to work it might be a bit stressful in a dark cave!
Exhausting way up but we were prepared and brought a lot of water and good clothing. It gets crazy hot on the path and you just drink constantly. Views are breathtaking, we relaxed at the top about 20 mins and came back down. It took us 4 hours altogether.
My favorite hike in Ko Phangan! It's the longest path so you can spend whole day hiking. Natural surroundings, beautiful views. Bring a lot of water though!
