The serene, majestic beauty of this Grove is a living reminder of the magnificent primeval redwood forest that covered much of this area before logging operations began during the 19th century. Armstrong Redwoods preserves stately and magnificent Sequoia sempervirens, commonly known as the coast redwood. These trees stand together as a testament to the wonders of the natural world. The grove offers solace from the hustle and bustle of daily life, offering the onlooker great inspiration and a place for quiet reflection. The ancient coast redwood is the tallest living thing on our planet! These remarkable trees live to be 500-1,000 years old, grow to a diameter of 12-16 feet, and stand from 200-250 feet tall. Some trees survive to over 2,000 years and tower above 350 feet. Coast redwoods are classified as temperate rainforests and they need wet and mild climates to survive. The rainfall in Armstrong Redwoods averages 55 inches per year and the trees are often shrouded in a mystical fog that helps to maintain the moist conditions needed for the redwoods to survive. To find out more about these magnificent trees click the link About Coast Redwoods to the right. The reserve includes a visitor center, large outdoor amphitheater, self-guided nature trails, and a variety of picnic facilities. While you can drive into the park, the best way to experience the dramatic effect of the towering redwoods, is to park in the lot at the park entrance and walk in for free. All of the main park features are found along the Pioneer Nature Trail. This trail is a mile and a half long round trip, mostly flat and level with one set of steps. Although no camping is available in the redwood grove, there is a campground at Austin Creek State Recreation Area, which is adjacent to the park. Austin Creek is accessed through the same entrance as Armstrong Redwoods and its rolling hills, open grasslands, conifers, and oaks are a beautiful and dramatic contrast to the dense canopy of the redwood grove. For more information go to Austin Creek State Recreation Area, click on link to the right. The redwood ecosystem is a very fragile one. Every effort is being made to preserve and protect this grove but it can only be done with your help. When you visit, please do not disturb or remove any natural features of the park, stay on designated trails and do not cross low- level fenceline. We hope you enjoy a serene and rejuvenating visit among these inspiring giants. 8:00 AM to one hour after official sunset.

Easy and short. Lots of great redwoods!

Stunning hike. Loved the terrain, the smells, the silence. Make sure you ask the Rangers if the Pool Ridge Trail is closed. We told the man at the visitor’ desk that we were doing the East Ridge/Pool Ridge Trail but where they meet the trail was closed and there were no signs. We called the ranger station and they said that the trail had been closed for a year but they were just now making the signs!!! He told us what to do to reconnect further down. My advice would be to NOT close a trail without having the signs ready to prevent people getting lost......

This is a beautiful hike with a pretty steady and challenging climb to a stunning view. We went on a foggy morning and ended up above the clouds at the top. The last bit of the hike takes you through the giant redwoods of Armstrong Woods. Stop by the ranger station for a free map before starting. Parking is free in the first lot you reach off of the main road. Recommend hiking shoes.

Love this trail for it's ease and peacefulness.

Great hike, significantly longer and greater elevation than posted (7.9 m/1700ft). Today was beautiful, but the views must be amazing on a clear day!

I’m biased as I LOVE Armstrong woods but as an obstacle course racer I find the variance in up/downhill as well as terrain change (roots, steps, dirt, rock, etc.) ideal for training. As well as ideal for beautiful scenery! Parking can be a bit crazy if you go during peak hours but you can park along the road right before the lot no problem. Bathrooms, trail stops, and signage adorn throughout (east ridge trail can be a bit wonky at the top though) so you never feel lost. Check it out!

My all time favorite

Great hike! There’s some debris down on the pool ridge trail and the signage is a little wonky once you get on pool ridge if hiking counter clockwise.

Ran this loop counter-clockwise, most of the elevation gain was in the first 3 miles. Once I reached the peak it was difficult to know which direction to go as there were no more signs for East Ridge. The Pool Trail finishes the loop, a small section of had some down trees to get around, but once I got around that the trail was better maintained from that point.

one of my favorite hikes in bay area.

Beautiful hike, but more moderate than easy. Starting from the visitors center, the hike up the ridge is steep. Left my poles in the car and wish I had them several times. We went to the falls which was barely running but still beautiful. We hiked the nature trail that goes through the redwoods.

Not an easy hike with over 2,000 ft elevation gain.

Really nice workout hike if you begin at the East Ridge Trail and connect to Pool Ridge Trail. Definitely would say going up East Ridge, especially near the top is rigorous, but that is where the workout begins. We loved it, but if you don't hike, you may find it challenging. Some doubts some may encounter on the trail I will address. When going up East Ridge there is an unmarked fork. One will go up and the other down. It doesn't matter which one you take since they both connect within a couple of minutes of walking. However, when you get to the fork and notice no signs, you do wonder if it takes you elsewhere. When you first go down Pool Ridge Trail, cross the fire road to continue. There is no sign but will see the path. Also,when you are going down Pool Ridge and get to a small parking lot and sign board, there is no posting of Pool Ridge to continue. Again stay straight and go across the fire road and stay on the path...it is just unmarked but that is the trail. Finally, when going down Pool Ridge and you pass loop trail, part of Pool Ridge is obstructed and closed off with no warning or alternative markings. You will want to take the Picnic Area trail which will eventually connect you back to Pool Ridge. Finally, bring lots of water because it is a 6 mile hike and it does get steep. When we hiked it was 100 degrees in Guerneville though about ten degrees cooler under the trees. The vistas at the top are really beautiful and worth the hike. We saw a few woodpeckers, turkey vultures, red trail hawk, lots of salamanders, and the usual squirrels. Bring a change of shirt because you will sweat and that will be more comfortable for your drive home. Get out there and enjoy this fabulous hike...we encountered just a few people and we went on an early Saturday afternoon. Unfortunately you could hear a few people yelling and playing music..seriously people use common sense, we are in nature not to listen to your loud conversation about nothing and for Gods sake unplug from technology or stay at the damn mall. Figure would throw in a common sense rant.

Challenging ish start but nice crest and a quick downslope to some pretty dang big redwoods.
Lots of contact with roads and stuff so it isn't like being way out there but it's a great hike with good variety.

love this hike. it is super steep but I like feeling the burn afterwards. very pretty home up. at the top a good view.

How long does this one take, for a moderately experienced hiker? Looking to make a plan with some others. Thanks!

We about died on the steep incline of the trail, but so did all the other people from what we saw! So at least there was something to laugh at - and the views from the top we certainly pretty, but not spectacular. However, our descent was marvelous (partly because it was downhill) and we found so many redwoods to stand in. There was still some active creeks, and we wish we had come earlier when the rains were still active to see it all in its full glory
