Da Lat was a really cute little city. I went canyoning while I was there and man was it fun! Just like the Elephant Sanctuary, the workers there were so entertaining and welcoming that it boosted the experience! The group of people I was with were also super amazing. Even though the majority came in their own little groups, we all talked to each other and got to know one another. Here is is a link to the website of the company I used. Viet Tours
I think there were a total of four waterfalls to canyon down on. In between the waterfalls there was a natural waterslide that you get to slide down on, and there is a little ‘trust’ section where you fall backwards into the water! To top it all off, they have someone taking photos of you every step of the way!
