Absolutely beautiful and a must-see. True wonder of nature! We went and walked on the Grove of Titans trail, which is about two miles total. They ask that you stay on the trail (because your footsteps can damage the forest floor) and there are some raised metal walkways because of this.
Though there’s a lot of roads and trails, it’s still a good idea to be prepared. There are countless areas where there’s no service, roads are dirt and are extremely narrow (but there are turnouts/shoulder areas where you can pass). BRING WATER AND SNACKS! It costs $8 per car if you park within fee areas. The parking lot by the Grove of Titans trailhead was free, and there’s a restroom there as well.
Absolutely amazing. Even within five minutes of our hike, a deer walked across the pathway. Didn’t seem to mind humans. It’s worth a visit! Also, if you get the chance, visit the Smith River — the water looks like glass.
