Again, many tour offers in Chiang Mai. The experience is great, river is fast so you don't get a chance to wander off with your thoughts as you need to be focused.
Fantastic For Snorkeling Especially In The Summer - Great For Sunsets And Beach Combing. I Got Married On Tunnels Beach In 2009 - It’s A Shame The Road Is Still Closed Since Spring 2018 Maybe Open To Tourists Late Summer 2019 ?
