★★★★★ ★★★★★ Great experience to see glowworms Blake 7 June 2017 Travelled by boat to an island and then broken into smaller groups to go through the glowworms caves. This included a boat ride to see the glow worms. If you have back problems it could be an issue as walking through the caves to do have to get down low under some of the rocks. Also to make sure each tour guide explains to keep quiet when on the boat as this affects the glow worms coming out. Was a great tour and experience
