Montgomery Woods State Natural Reserve

The redwood Shangri-La
California > Mendocino/Sonoma region

Montgomery Grove


At the heart of this exceptional reserve is a small alluvial flat hidden away in a remote, steep-sided valley, with one of the most scenic redwood groves in existence.

This serene little grove is isolated in more than one sense. It's unusually far from the ocean, at the eastern edge of the redwood band and surrounded by relatively dry environments. It's also well off the beaten track, a half-hour from the nearest freeway or town on steep and winding roads, and, unusually for a redwood park, the old growth grove is well away from roads and other development. As a result, Montgomery is amazingly quiet.

Although it wouldn't seem like people would drive all this way for only two miles of trails, the reserve is a fairly popular destination that gets maybe 3–6 cars per hour on summer weekends. Its popularity may be partly due to the fact that, at one time, Montgomery Flat contained the tallest measured tree in the world. While its location is secret, and taller trees have since been found in other parks, that distinction still gives the grove a certain cachet and is especially surprising for such a small, remote park.

If the little 7-car lot is filled up, which happens even on weekdays, park in the dirt pullout across the street.

Like many redwood groves, the best time to visit Montgomery Woods is late in the afternoon. There are fewer visitors at this time so it's easier to appreciate the serenity of the park, and the valley is oriented such that late-afternoon summer sunshine reaches the valley floor, providing a softer, more scenic light than the harsh midday sun.

Montgomery Woods, being so far from the coastal fog bank that keeps redwoods hydrated in the summer, gets quite dry-looking in late summer and fall and doesn't feel nearly as special. What's more, even at its best the grove isn't as overwhelmingly lush and dense as it used to be, due to a 2008 fire that was followed first by years of drought, then floods in 2017 that scoured away the groundcover in some areas. In contrast, the groves of the North Coast get much more reliable rainfall as well as more summer fog, so they haven't been as affected by the drought and also don't change much from season to season.

Orr Springs Road


Here's the trailhead location in Google Maps and Google Street View.

The reserve can be reached by taking Orr Springs Road west from the town of Ukiah. It's about a 30 minute drive from Highway 101. Orr Springs Road starts just north of exit 549 and soon begins a steep and twisty climb, which is then followed by an even steeper and twistier descent through scenic oak chaparral. Redwoods line the creekbeds below. Once it reaches the valley floor, the road levels out and passes Orr's Hot Springs, then enters a redwood forest. Look for a large wooden sign on your left.

The reserve can also be reached by taking Comptche - Ukiah Road and Orr Springs Road from the coast. This route is easier to drive but less scenic, winding its way along a wooded ridge before dropping into the valley. After passing Comptche, simply follow the only paved road — there are no turns to make.

The reserve is sometimes marshy, so if it's summer and you don't have mosquito repellent, you might be surrounded by an impressive cloud of mosquitos the moment you stop to take a picture or admire a view. Poison oak is also common although it doesn't usually encroach on the trail.

The reserve is not staffed and there's no entrance fee.

Hike description

The trail starts off as a dirt road that climbs through a rather mundane redwood and tanoak forest alongside a burbling creek. After a third of a mile, the trail crests and then descends slightly to Montgomery Flat. At this point, the forest changes dramatically, from nice but rather ordinary redwood uplands into a classic, cathedral-like alluvial flat forest. The thick mats of sound-absorbing redwood needles on the ground give the grove a noticable quieness. The grove is tucked into a little glen with sides that rise steeply and abruptly, cutting it off from the outside world and giving it a uniquely sheltered feel. The quiet isolation of the grove, combined with the strikingly lush vegetation, turns it into a little paradise.

Just as the trail enters the grove, it passes through a large area where the ground cover has been worn away by foot traffic. Although it's hard to tell, this is actually a trail intersection and is both the beginning and end of the loop trail. The loop trail winds around the perimeter of the grove, sometimes elevated above the marshy alluvial flat at its center.

The first one-third mile of the loop trail, up to the Kellieowen Grove, is actually a little plain compared to the rest of the grove. This is partly because the 2008 fire most heavily affected this part of the grove, scouring away the lush groundcover and leaving fallen trees and blackened trunks. However, even before the fire this part of the trail was less scenic than the rest of the grove. This part of the trail turned into a gravelly creekbed after the heavy rains of 2017.

Montgomery Creek

Past the Kellieowen Grove, the scenery improves again as the trail winds up and over a gentle rise and then runs alongside a small gravelly creekbed that's dry in summer. A few yards away, Montgomery Creek burbles quietly. The ground cover is an especially plush carpet of sorrel dotted with large ferns, indicating that the valley is well-watered. In places the flat is filled with a remarkable sea of ferns.

A long footbridge built on a fallen tree marks the halfway point and crosses the marshy center of the flat. The unofficial spur trail to the right runs through a logged area and eventually reaches an unlogged grove of small redwoods at the intersection of two creeks. This bright, open grove isn't nearly as spectacular as the main grove, but it's still interesting.

The main loop trail works its way back, now on the north side of the flat, past some impressive redwoods; this is an especially scenic part of the trail, especially in the late afternoon when the trees are backlit. The ground rises steeply to the right, making a fern-encrusted wall.

There's a short, deteriorating boardwalk and then comes one of the most interesting parts of the trail, where it crosses back over Montgomery Creek, winding for a stretch among some picturesque burbling pools and a huge fallen tree. Even in late summer, when the flat has mostly dried up, there are still deep pools of water in this area. Emerging from this shady crossing, the loop trail ends at the Y intersection with the dirt road to the parking lot. A few short spur trails to the right cut through the plush redwood sorrel on their way to the creek, and are worth exploring.

New acquisition

One mile east of the main grove parking lot, on the north side of Orr Springs Road, is a newly-acquired property purchased by the Save-the-Redwoods League. An unmarked trail follows a little creek into a canyon lined with old-growth redwoods, some of them pretty good-sized. A quarter-mile in the trail crosses a creek, and shortly after the old-growth redwoods end. The trail isn't as clear after this point, but it continues for a total of 0.8 miles before entering private property. The old growth here doesn't compare to the main grove; it's similar to what you see on the access trail that leads up to the main grove.
