WALKS CHALLENGING WALKS These are super-exciting walks over mixed terrain to reach spectacular destinations. They involve scrambling and sometimes walking or swimming in water. Fitness is important as you can expect to be walking for many hours often in hot temperatures on paths that offer little shade. It is easy to see why walking through a gorge in water is challenging, but why is following a path to the Neda waterfalls equivalent? The answer is that although the path DOWN to the falls is straight forward, the last stage is cliff hugging and the walk back UP the road is strenuous.
