Glow Worms. Visit McLaren Falls Park, Tauranga.  Kayak on a calm, safe waters of the lake before entering the river, shrouded in native bush. As it gets dark hear the haunting call of our own native owl the Ru Ru (Morepork) and watch the speckles of the glow worms amongst the bush.  Brace yourself as we enter the canyon and witness the spectacle of the glow worms covering the steep cliffs of the canyon.
