This is a really unique tour on a semi-submersible vessel that brings you up close to giant whales from a new perspective! The yellow submarine tour runs from Puerto Piramides from Jun-Dec. As you step down into the lower part of the boat, look out to the ocean around you in a moving aquarium. Appreciate the magnificence and size of the southern right whales that ply the waters of Golfo Nuevo. Forty windows (20 on either side) in the underwater cabin welcome you to life under the sea. On board, you can move freely and choose the ship’s upper deck to observe wildlife from the surface of the water as in traditional whale watching excursions or go underwater in the cabin to “dive” into the underwater world. There is also a whale-watching guide onboard on hand to explain the characteristics of these mammals.
