★★★★★ ★★★★★ Nice glow-worm spot. Zebediah 7 May 2018 Karapiro is lovely. Great spot for glow-worm viewing. The tour involved a lot of unnecessary waiting around: an hour at the start and an hour in the middle on a small inlet on the river. Recieved very little commentary on the area or its history in these long gaps - which is what we are most interested in. At the end, we felt we would have been better to rent our own kayaks and do the same for a fraction of the price and not have long waits.
