Hike up to Khao Daeng Viewpoint
Not too far from Sam Phraya Beach, you will find Khao Daeng Viewpoint, a stunning trail that you can hike up to the top of Khao Daeng Mountain and you will be rewarded with an aerial view of the beautiful Sam Roi Yot's coastline in its entirety. The hike itself is moderate that takes around 30 minutes to 1 hour to complete. The trail is clearly marked but it is full of rocks and boulders so you are going to need to wear proper shoes for the hike.
Once you are about to arrive at the top, you will come out into an opening and you will be able to enjoy a 360° panoramic view of the coastline as well as Sam Roi Yot mountain behind. This is where you will be able to really appreciate just how secluded and beautiful Sam Roi Yot's coastline really is. The hike is located within Sam Roi Yot National Park and you will have to pay for the entrance fee if you have not done it yet. It's 200 THB for adult foreigners, 100 THB for children, 40 THB for adult Thai, and 20 THB for children.
