I did read about this Giant Tree and while riding from Lampang to Chiang Mai I passed this place. It is a coffee shop & hotel build in a Giant Treet. And you can even make a short zip-line journey. It was not easy to get there as it is about 50 km out of Chiang Mai town and the last 4 km is a narrow & steep road with bad road surface. Of course you could ask yourself "Is this not destroying the beautiful natural landscape?
