Introduction
Hendy Woods has two beautiful groves of coastal redwood trees - Little Hendy and Big Hendy. Both are accessible from the campground. There are a few miles of trails in the park and a river flowing by to explore. We would stay at this park again if we were in the area, but we wouldn't go out of our way to visit again as there are plenty of redwood groves that we need to see.
Insider Information
This park is a great stop over when traveling between highway 1 on the shore and highway 101 further inland. However, for the price it leaves a lot to be desired. The park lacks hookups and you have to hunt to find water spigots with a threaded connection. In the Azalea campground there was a decent shower house with flush toilets and showers. At the other end of our campground was an older set of bathrooms that really seemed neglected. They weren't dirty, just had very old fixtures, flaking paint, rotting wood, etc. We've seen much better pit toilet setups.
Camping
The website lists the max trailer length at 35 feet and we did see a few bigger rigs. While we were there most sites were occupied by smaller rigs and tents. If you have a bigger rig you should definitely check google maps for the specific site because they varied widely. The site across from us couldn't fit their 5th in site #29 and fortunately were able to move to #31 where it barely fit. The sites are well spaced with lots of of trees (which rules out Starlink) and mostly level. We were able to level our 19' van with 3" of blocks under the back 2 wheels.
Amenities
The park lacks hookups of any kind and most of the water spigots lacked threaded connections. There were plenty of garbage dumpsters and a dump station. One set of bathrooms was pretty run down but the shower house was newer and both were clean. All had flush toilets. The shower house had our favorite single room showers with locking doors. It also had 2 single room bathrooms with locking doors. The showers were paid and take quarters.
Activities
The main attraction is the coastal redwoods in the two groves - Little Hendy and Big Hendy. We walked Little Hendy 1/2 mile loop from the campground trail. Getting into and out of the grove is short uphill/downhill path. Once into the grove the path is pretty flat and well maintained. Big Hendy is accessible from the campground, but we chose the short drive to the day use area (we needed solar charging). The Big Hendy trail head has pit toilets and water available. The trails through the grove are very well maintained. We found them a bit confusing to follow since people seem to walk off the trail quite often. The area is flat and the trails are very easy. Many are rated as ADA accessible.
Nearby
There isn't much nearby so make sure you stock up on food and gas before heading over. We mainly used this park as a nice break while moving from highway 1 to highway 101. It's a beautiful drive and the park has some beautiful hikes.
