If you ever make a trip to New Zealand, it would be a shame to missRiwaka Caverns. Rikawa Caverns are the best place if you like cave diving. Rikawa River is situated at the base of Tikaka Hill. The cavern is narrow when you start your dive-journey, but it gets much wider as you reach in the middle. The climax of Riwaka Caverns is a huge chamber which will leave you gasping as the wall is made of pink limestone. As you take a peaceful swim in this place, you will witness a change of color in water as well which will leave you wonderstruck. Cavern itself offers spectacular views with every inch you swim and you will never forget the wonderful experience of Riwaka. Riwaka Caverns is definitely full of mystery, adventure, and doubtless fun.
