This is Taiwan's longest stretch of sansd dunes, over 8 KM in length. Formed over thousands of years from silt washed into the ocean from nearby rivers, these dunes have become a popular spot for Instagrammers looking for unique geological features close to Taipei. Despite being a great place for photos, the area remains relatively quiet on weekends due to limited transportation options. So, if you're up for an adventure and some stunning views, the Caota Sand Dunes might just be the perfect spot for you!
