There are many tour operators providing whale watching trips but make sure you choose the ones who don't tend to have a great impace on the natural behaviour of these magnificent creatures.
Whales come in all sorts and sizes and can be found all over the world. In some sad and luckily rare occasions you can find it on the news that a huge whale was found ashore on your local beach, meaning they are still finding their way to more unfamiliar grounds. To this day there are to believe over 19 species of whales, from which the blue whale is considered the largest of them all and can reach a length up to 29.9 meters or 98 feet, that's around 6 large cars place behind each other. Local travel agents know the ins and outs of where to find these unique whales in their area, it's wise for you to read upon this and also make sure your enthusiasm to see these whales don't interfere with their natural habitat. Tourism is beautiful, as long as it's balanced to preserve both nature and animal kingdom.
