Redwoods are something special, you just know when you are around them. Giant well kept in a beautiful reserve area. I went both in the daytime and nightmare specifically to see them, but there is lovely places to walk all around this area, with a picnic, with a dog or just some time alone. The redwoods themselves arnt as big/wide as the ones in california, but that doesn't mean they arnt spectacular to look at. Many have survived wars and carry so much history. I would reccomend visiting both day and nighttime, specifically to do the nighttime walk, it adds a sense of mystery and quiet to the surroundings. Make sure you go as late as possible- if you do go to avoid small children and noise. We left when the last groups were coming in and it was deffintely the best time to visit. There are bridges with platforms with a limit to 8 per bridge and 20 to platforms which is great because it means on some platforms it doesn't get overcrowded, as long as you are visiting with people who adhere to the rules. The height isn't much of a problem for those who are scared of heights for the lower course, but there is a section that goes a little higher which you do not have to go down, there is a alterative route also. Make sure you look up at the sky, as the stars are nice if you stay away from the road. Worth a visit if you are passing or in the area, they are wonderful trees.
