Montgomery Grove


At the heart of this exceptional reserve is a remarkably lush little oasis of tall redwoods that’s hidden away in a remote, steep-sided valley like a redwood Shangri-La.

The serene little alluvial flat grove is in an unlikely place, unusually far from the ocean, surrounded by dry-looking redwood uplands and hot, sunny grasslands. It’s also well off the beaten track, a half-hour from the nearest freeway or town on steep and winding roads. Unusually for a redwood park, the old growth grove is well away from roads and other development and is completely quiet except for the sound of the wind in the trees.

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.

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.

The best season is spring, when the grove is at its lushest. Being so far from the coastal fog bank that keeps redwoods hydrated in the summer, Montgomery Woods sometimes gets a little dry-looking in late summer and fall and doesn’t feel quite as special.

The grove also changes a lot from year to year. In particular, it lost much of its attractiveness after a 2008 fire that was followed first by years of drought, then floods in 2017 that scoured away the groundcover in some areas. Fortunately it’s recovered well and the grove is now just as scenic as it used to be.

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 Mendocino. This route is easier to drive but less scenic, winding along a wooded ridge before dropping into the valley. After passing Comptche, simply follow the only paved road — there are no turns to make.

If the reserve’s little 7-car lot is filled up, which can happen even on weekdays, park in the dirt pullout across the street.

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.

The trail is wide and easy to follow, but the footbridges are in poor repair, with missing planks and smashed handrails.

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 make the grove strikingly quiet. 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 remarkably 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 start 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, up to the Kellieowen Grove, is a little plain compared to the rest; it also turned into a gravelly creekbed after the heavy rains of 2017.

Past the Kellieowen Grove, the scenery improves 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.

Montgomery Creek

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.

Montgomery Grove

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 otherwise completely 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

A 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 more like the access trail that leads up to the main grove.
