Mount Hood National Forest Clackamas River Road
Timber road through old-growth forest to hot springs
Forest Road 46 follows the wild Clackamas River for 40 miles through Mount Hood National Forest, passing Bagby Hot Springs and threading between clear-cuts and cathedral groves of old-growth Douglas fir. This was the main timber highway into the upper Clackamas basin, and you’ll see remnants of splash dams, logging railroad grades, and abandoned mill sites. The road crosses the river multiple times on historic wooden bridges before ending at the Clackamas Lake trailhead beneath Mount Jefferson.
Easy to moderate difficulty suitable for any high-clearance vehicle, though winter closures run October through May due to snow. Stock up in Estacada—no services for 40 miles. The road can be dusty in summer logging season and muddy during spring melt. Dispersed camping opportunities abound along the river, and Bagby Hot Springs offers a perfect soak after dusty miles. This is classic Pacific Northwest forest driving through some of Oregon’s most pristine timber country.

Frequently asked questions
Can a stock 4Runner or Tacoma handle Clackamas River Road without modifications?
Yes — stock high-clearance rigs like a 4Runner, Tacoma, or Wrangler are the minimum you want here. The gravel road is moderate and manageable, but low-clearance vehicles like sedans or crossovers will struggle with ruts and water crossings.
When does Clackamas River Road open and close each year?
Best window is May through October. Snow and mud can make the upper sections impassable in early spring and after fall storms. Check with Mount Hood National Forest before heading out — gates can close without much notice.
Do I need a permit or pass to drive Clackamas River Road?
No permit is required to drive the road, but a Northwest Forest Pass is needed for designated trailheads and some day-use areas along the route. Dispersed camping is free and generally doesn't require a reservation.
What's the hardest part of this trail and what should I actually expect?
The water crossings are where most people pucker up — depths vary by season and recent rain, so scout before you cross. The road itself is well-worn gravel with some rutted and washboarded sections, but nothing that'll have you winching on a dry summer day.
Is there cell service along Clackamas River Road, and how far is the nearest gas from the trailhead?
There is no cell service on this trail — plan accordingly and download offline maps before you leave. Estacada is your last reliable fuel stop, about 26 miles from the start of the route, so top off there.
