What to Expect

IMPORTANT STATUS NOTE: This trail has been closed since 2021 due to damage to the suspension bridge that connects to the island grove. Check with the park before planning a visit. When open, this is one of the easiest and most awe-inspiring walks in Mount Rainier National Park. The flat, well-maintained path winds through old-growth forest along the milky-blue Ohanapecosh River before reaching a suspension bridge to a small island where ancient western red cedars and Douglas-firs — some over a thousand years old — tower overhead like living skyscrapers. The trunks are so massive that four adults linking arms can't wrap around them. A short boardwalk loop circles through the grove, and the silence under that canopy feels almost cathedral-like. This trail is perfect for families, anyone with limited mobility who can handle a dirt path, and hikers who want maximum payoff for minimal effort.

Safety Advisory

The Ohanapecosh River looks calm but runs cold and fast with a deceptively strong current — stay on the bridge and boardwalks, and keep children close near the riverbanks.

Damaged or improvised river crossings (logs, rocks) are not safe alternatives if the official bridge is closed. People have been swept away attempting unofficial crossings in this drainage.

Pro Tips

Trail Tip

Check the NPS Mount Rainier alerts page before driving out — the suspension bridge has been damaged since 2021 and the trail may still be closed when you read this. The Ohanapecosh area is in the park's southeast corner, a solid 90-minute drive from the Paradise or Sunrise entrances.

Trail Tip

If the trail reopens, arrive before 9 AM on summer weekends. The small pullout parking area fills fast and there's no overflow lot. Weekdays in September are the sweet spot — fewer crowds, fall color starting, and the river running lower.

Trail Tip

The biggest trees are on the island loop, not along the approach trail — don't turn around early thinking you've seen the best of it. The largest cedar is just off the boardwalk to the right after you cross the bridge, and it's worth walking the full loop counterclockwise to build up to it.
