Should you have only one day and would like to see the main tourist sites in Bali here is an idea. Most visitors to Bali especially fist timer will like to see main places like Mount and Lake Batur (known as ‘volcano’ or Kintamani), temple of Lake Bratan , Tanah Lot and Ubud.
If this is your case and you stay either in Ubud, Sanur, Kuta or Seminyak, you can start by visiting one of craft village around Ubud (please don’t go to everyone of them and spent to much time) then to Tegalalang Rice terrace and off to Batur area for the caldera view. You can also visit Batur Temple , the second largest temple in this area. After Batur a long drive passing windy and scenic route crossing the longest bridge in Bali to Bedugul area. Beside the popular floating temple of Lake Bratan you can also can spend some time in Candi Kuning fruit and flower market before cruising down to the coast to Tanah Lot.
