Save 10% with code RANKERS

The Glass Bottom Boat is a solid two hours out of Whitianga, cruising into the Te Whanganui-o-Hei Marine Reserve and along that dramatic volcanic coastline toward Cathedral Cove. You're getting above and below the waterline through the glass panels, plus the option to jump in and snorkel with gear provided. It suits pretty much any age or ability level, which is genuinely true of very few boat tours.

Most travellers rate it well, though a couple of things are worth knowing. The viewing through the glass is heavily dependent on water clarity, and a few reviewers noted it was a bit cloudy on their day. Can't control that, unfortunately. Some also felt the price was on the steeper side. Fair enough, it's a niche experience. But when conditions are good, this is a cracking way to see the reserve and the cove from a perspective most people don't get.

I'd pick a calm, clear day if you have flexibility in your schedule, and book the earlier sailing if there's a choice. Use promo code RANKERS to save 10%, which helps take the edge off the price a little.
