I was lucky enough and bought tickets two month ago (otherwise it's sold out) to visit the best place to see Northern Elephant seals.

Elefant seals are really fascinating animals:

• the females travel back and forth from Hawaii to give birth every year.
• the males stay on the beach during 3 months without eating of drinking
• after 21 days, the new born seals are abandoned and must learn how to swim and eat by themselves
