One of the best things that can happen to you while scuba diving is to have a chance encounter with whales. For most people, they will never soon forget this surreal experience. Not all scuba divers will have this opportunity. Oftentimes, it takes a lot of dives before you can even spot one.
Moreover, there are only a handful of countries where they can be seen. Whales often come near the shore to breed and mate. In some countries, whale watching is regulated and it is forbidden to swim near them or even approach them.
