One of Australia's best-kept secrets is starting to rise in popularity thanks to Instagram [1] — the Figure 8 Pools. The rock pools in Sydney's Royal National Park [2] may look man-made, but they actually formed naturally over time. Visitors have been taking the three-hour hike to visit the unique destination and jump in.

The important thing to remember is to visit the Figure 8 Pools at low tide — it's too dangerous to check them out at high or even mid tide [3]. Waves will crash over the area and can cause injuries. Just make sure to check the national park safety alerts [4] before making the trek. If you follow the guidelines and be careful, it's a memorable visit that's totally worth it.
