A very slickly and well organised tour, starting off with a boat trip in a large modern cruiser to the landing pier close to the caves. The initial trip takes around a half hour across Lake Te Anau and then disembark for the caves.
GIVE YOURSELVES A GOOD COATING OF DEET (anti mosquito liquid) as there are clouds of Sand Flies at the entry to the caves.
Although it is a real "duck down" to get into the first section of the caves, I can safely say that the fantastic walkway and lighting system will give you a superb view of the massive flow of underground waters crashing down through the layers of sandstone into the underground rivers where, almost incidentally, there are delightful displays of the glow worms gently winking from the ceiling.
A most unusual but "fun and educational" trip that is really worth your time.
