Enjoying the scenic seascape and taking photos and selfies from above would be sufficient for most. You can enjoy the sweeping views from a purpose-built platform, which is bordered by bamboo fences.
If you dare the challenging trek down to the beach, make sure it’s during low tide. Some sections of the path can be steep, requiring a bit of rock climbing, especially on the way back up. Locals have put rocks and bamboos to aid visitors over the years.
Once you’ve reached the sand, you’ll have it all to yourself most of the time. Depending on tide conditions, the waters are swimmable. However, note that the undercurrents can be strong, and being the remote site that it is, there are no lifeguards around. Besides your camera and a good pair of shoes, be sure to bring drinking water with you on the descent, to keep you hydrated.
