Dabaisha (Great White Sand Beach) is located in south of Ludao island, one of the famous diving spot. Without swimwear, you can go through the bridge and enjoy coral sea and some small fishes. On fine day, you can see Lanyu 蘭嶼 island (another resort island at east of Taiwan), about 60km far on the sea.
The cache is small tupperware, hidden around the rest spot above the Dabaisha. On summer days, there are many muggles, so please be careful when searching.
