It's no wonder where Karijini National Park gets its stunning natural features from. With gorges dappled across the park, there are so many hidden treasures to discover. Secluded swimming holes, breath-taking waterfalls, unique rock formations and vast open roads are just some of the incredible sights that THISWORLDEXISTS ambassador, Tom Jessett, explored and photographed.

Located inland off the western Australian coast, temperatures at Karijini can get extremely hot, easily reaching 40 degrees Celsius and over during summer. The best way to beat the heat is to explore early in the day or late in the evening, or take a dip in the refreshing, luscious waterholes.

2. Zion National Park

A popular destination visited by many tourists from all over the globe, Zion has some fantastic trails and must-see destinations. Located in the Utah desert, USA, and similar to Karijini, it gets pretty hot out there. Two of THISWORLDEXISTS' ambassadors, Kasey Crook and Wesley Hawkins visited Angel's Landing, one of the most popular destinations, and Observation Point, which is a lesser known destination in the park.

Not for the faint-hearted, the Angel's Landing hike is a strenuous journey, but worth it when you're met with these stunning views.

Aptly named Observation Point is a must-see, also boasting outrageous views across Zion.

4. Wilsons Promontory National Park

Located on the southernmost tip of Australia's mainland, Wilsons Prom is home to the famous Squeaky Beach, where the sand literally squeaks as you walk across it. Hot spots like Mt. Oberon and Tidal River attract thousands of tourists a year.
