Grove of the Patriarchs Trail

Overview

This is Mount Rainier’s classic big-tree stroll in the Ohanapecosh area: a short, nearly level nature trail showcasing ancient old-growth on an island in the Ohanapecosh River. When fully open, the route is about 1.1 miles round trip with only minor elevation change (~50–100 feet) and loads of interpretive signage—perfect for families and anyone who loves learning while they walk.

Important status note: the suspension bridge that accesses the island loop has been closed since 2021 due to flood damage, and reconstruction isn’t expected before 2027. Many listings mark the trail as closed; check current conditions before you go. Without the bridge, the hallmark island loop is not accessible.

What You’ll See

The grove is a living museum of Pacific Northwest giants—Douglas-fir, silver fir, western hemlock, and western red cedar. Some trees here are centuries old (around a thousand years), soaring over 200 feet with massive girths. Underfoot and all around: lush ferns and mosses that thrive in the river-valley humidity, giving the forest a temperate-rainforest feel, especially on cloudy or rainy days. The maintained tread and raised boardwalks (in the grove) protect roots and keep feet out of the worst of the wet.

Distance, Effort, and Timing

Plan 40–60 minutes at an unhurried pace when the loop is open (about 1.1 miles total). With the bridge out, the signature island loop cannot be completed. Effort is minimal; grades are gentle and footing is straightforward, though sections can be muddy after rain.

Crowds and Logistics

This is one of the park’s most popular easy walks. The small lot near the Stevens Canyon Entrance off WA‑123 fills quickly—arrive early, especially on summer weekends. There are restrooms at the trailhead. Pets are not allowed. Expect single-file, one-at-a-time crossings on the suspension bridge when it reopens, which can create short waits.

Best Time to Hike

Summer and fall are the sweet spot for drier tread and comfortable temps. Spring and winter can linger with snow or slush. If the mountain is socked in, this forest still shines—misty, even moodier, and great for photography. Weekdays and early mornings beat the crowds.

Tips and Nearby Alternatives

Wear sturdy, preferably waterproof footwear; mud is common after rain. Slow down and read the signs—this is a self-guided nature trail, not a speed hike. If you’re looking to extend the day or the bridge remains closed, consider nearby options: the Eastside Trail toward Deer Creek Falls or the Silver Falls area—both deliver flowing water and quiet forest without depending on the suspension bridge.
