Khao Lom Muak in Thailand's Prachuap Khiri Khan province is a must-see spot for adventurous explorers. The beachside hill offers breathtaking views of nearby bays, islets, and the town. Only open a few times a year, climbers are welcome between 6:00 and 10:30 am to ascend the 300 meter peak. Registration is required, and remember to bring water, the proper footwear, and gloves. After a two hour climb, you'll come across a rope trail leading to a limestone cliff, then head back down to sea level by noon. Prachuap Khiri Kahn can be reached in an hour drive from Hua Hin resort town. With many outdoor activities, nature trails, and lookouts, Khao Lom Muak is a great way to take in some of Thailand's gorgeous vistas.
