Khao Yai is just 2 hours from Bangkok and you will experience romantic scenes and romantic moments. It is very beautiful and clear water. The life jackets were clean. We went on weekend, not a lot of people. Good to try it was fun. Follow me here @lifeinthailandnow #khaoyai #thailand #thailandtravel #naturelovers #waterfall | Life in Thailand Now | Facebook
