I walked southward on this west coast of Southern Thailand and if I insisted on walking further in another 20km, that would be Thai Mueng beach where my best friends were there without me. So spiritually I could have re-joined them in Thai Mueng beach. If I further walked another 20 km southward, then I'd be in Natai beach, where my favourite resort Aleenta is. I could just stop by and simply say hello to friends over there. It may take about 6 hours in total if I walk for 40km.
Khuk Khak beach is a quiet beach and the sand is so golden sparkling as if they were speaking to you. It's also very powdery as if you were walking in melty cotton. Check the last few photos, some interesting tree-like pattern is left on the receding area.
