Pacific Rim National Park has two short boardwalk trails that take you through the forest, aptly named 'Rainforest A' and 'Rainforest B.'

Both boardwalk trails are 1 kilometre long and feature stunning old-growth forests with massive trees, mossy undergrowth, and thick ferns. You’ll need to tackle a few steps on either trail.

I really like both A and B loops, but if I had to choose, I'd go for 'Rainforest B' as my favourite.
