Castle Gorge Parking is one of the best-kept secrets of Johannesburg. With cascading waterfalls, natural swimming pools, and amazing views, it's not one to miss. This really is a hidden gem.

It's an excellent destination for hikers in the area of Gauteng, South Africa and has a 13.5km (total) out-and-back trail. The park also offers a secure parking area with a gate to keep vehicles safe. Permits are required and can easily be bought online at Quicket.co.za.

It's recommended to download the AllTrails app before you go, as the trail isn't too well marked in some spots. When you get to the waterfalls, be careful as the path isn't clear and always make sure you can get out of the natural pools before you jump in.

Have a fantastic time and bring lots of water.
