There is a new group for Taiwan travel videos on YouTube. There are some interesting videos of Taiwan's high mountains and also Atayal dances. I particularly like this one of the hip bells worn by the Atayal. While on the subject of the Atayal I must also recommend this wonderful photo set of the Atayal by CleverCl@i®ê at flickr. The photo above is from that set.
Another interesting Taiwan video I found on YouTube was Youth travel in Taiwan. I guess it has been professionally produced for the Taiwan Tourism Bureau. I think it does a good job of showing that Taiwan is rich in attractions beyond the most commonly promoted ones like Taipei 101 and the National Palace Museum.
While I doubt Taiwan will ever be a mass tourism destination like Thailand there is plenty to be discovered here by the more adventurous traveller looking for something different.
