The Otways in Victoria, Australia is a national park that is largely (I think) a temperate rain forest. There are a lot of great "off the beaten path" waterfalls/campgrounds/etc, but a lesser known (I don't really hear about tourists going there) place is the Californian Redwood forest. It is serene. For part of the time I was there, I was pretty sure I was the only person around for kilometers, and this ancient silence was heavy throughout the forest (when not by the bubbling brook). There was no mobile phone reception. It is just you and nature. Under the redwood trees it is dark (Google's Enhancer auto-brightened the photos), quiet, and ominous. It was amazing. The ground under the core bunch of trees has no plants on it, not even small ones can grow due to the lack of light. There's only branches of tree needles in various states of green/brown, depending on when they fell from the trees.
It was chilly and damp, but an amazing place to be. I need to go again when it has warmed up. Being there on your own feels like something special. I like a lot of the Otways, but that place is now my favourite.
Due to the phone's crappy microphone, it really couldn't properly pick up the brook, which sounded like a real small waterfall/bubbling brook. It was extremely peaceful. The microphone properly picked up the absence of sound that was in the second video taken away from the brook. It was wild how muted everything was. I felt like I was imposing on an ancient world. These trees are only ~90 years old, too!
