British Columbia has more than 16,900 mi of coastline (including all the islands) between the southern border with Washington State and the northern border with Alaska. That is quite some distance. Flying north along the coastline you have an opportunity to witness just how deep some of the inlets really are, and there are many of them stretching for miles into the interior of the Province.

Walking along the shores during a receding tide you will find all sort of sea life. Many seek shelter to hide keep from being a food source and to keep out of the sun until the tide comes back once again.
Looking down (and depending where you are on the beach) you can find small crabs, shells of many descriptions (some intact with a mussel inside) and even sand dollars in some locations.
Take advantage of our shores. Watch for areas where tide activity may be quicker than you are used to other wise you may get wet trying to get back to dry land. Always be careful when playing around tidal pools as some of them can be quite deep.
Enjoy, enjoy, enjoy!
