OMG! I am so jealous. I’ve only been to the Redwoods once, when I was a really little kid. What I do remember about it is just the “atmosphere” of the place. The beams of light wafting through the misty air, the warm and cool temperatures that changed when you went from sunlight to shade and the smell. The smell of an evergreen forest cannot compare to anything else, epecially when you are camping and cooking bacon and making coffee and those aromas are mixed with the scents of pine needles, and moist, rich earth.
Make sure you take a camera with extra batteries and extra memory chips (if you won’t have access to electricity or a way to download the photos). Bring a notebook so that you may record your daily observations about what you saw, what you heard, what you smelled, how you felt. You can also make notes about certain plant and animal species that you encountered so you can research them more when you get home.
Right now I’m having one of those “extreme camping lust” moments. In my mind I’m seeing little bitty mushrooms and transluscent light coming through the fern groves. I can hear and smell the trickling of a nearby stream, I can see red and blue dragonflies and floaters skating across the water. And I can hear distant echoes of footsteps and voices and birds chirping and woodpeckers pecking- conk, conk, conk.
Technically you are not supposed to take things with you, but try to find a tiny stone or a dried leaf or a piece of moss or a chunk of bark (something very small) so that you will always remember this place.
