Pacific Rim National Park is located on the west coast Vancouver Island. It comprises a Pacific coastal ecosystem and is known as the surfing capital of Canada.
The park is actually consists of several parts along the coast of the Pacific Ocean. The Long Beach section is the easiest to visit and has the best access. The West Coast Trail section is technically closer to Victoria, but has no easy access. This is important to note because when you look at the park on a map, it might seem that the park is closer to Victoria than it actually is if you want to visit.
To reach Long Beach you have to drive up the eastern shore to near the town of Courtney and then across the island. Expect a 2-3 hour drive from Victoria or closer ferry terminals. The nearest towns are Tofino and Ucluelet which sit on either ends of the beach.
As you can see in the photo, there was a very thick fog over the beach when I was there. Just a mile inland, however, and the fog was totally gone and the sky was blue.
