One of Nha Trang's most alluring attractions is the Po Nagar Cham Towers, an actively used site of religious significance to Cham, Chinese and Vietnamese Buddhists; only 4 towers remain standing (researchers speculate there may have originally been up to 10). Constructed between the 7th and 12th centuries, the towers have a history that goes back to as early as the 2nd century AD when the location was first used for religious purposes. The complex teems with worshippers and visitors daily – you'll likely see some dozing on the hillside, others having a family picnic, and others yet enjoying a stylised performance at the on-site outdoor stage.

The sea around Byron Bay has abundant marine life among the rocky reefs. If you are not a certified diver yet, Byron Bay Dive Centre is the place to go for a guided experience and maybe complete your training. They will take you to the beautiful Julian Rocks Aquatic Reserve, one of Australia's major diving sites.

There are two waterfalls in the vicinity of Nha Trang, both of which make for excellent excursions into nature. Ba Ho Falls, at a distance of roughly 30km north of central Nha Trang, are the falls that attract most visitors. You will need a ride to reach the entrance to the natural area (get a taxi or Grab). Bring swimwear, sturdy shoes (not flip-flops), and your own water. Note that water volumes may vary dramatically depending on whether you visit during or outside the dry season (January through August). Another option is Fairy Spring Waterfalls (Suối Tiên), mostly favoured by local youth. These are much smaller compared to Ba Ho, but there is still an opening fit for swimming. There is a small admission fee to visit both falls.
