McKenzie East and Terwilliger

Terwilliger, also called Cougar Hot Springs, is the one named destination recovered here. The current Forest Service page marks it open and describes four soaking pools; the old 2014 upper-pool closure is not treated as a current restriction. Thermal bathing and surrounding reservoir activities have separate rules.

Keep the real soaking opportunity and current fee

The Forest Service's July 9, 2026 page is marked open and describes four soaking pools. Its current fee is $12 per person per two hours for ages 12 and older, not the archive's 2013 price. No additional three historical swimming entrances were recovered.

Clothing and pet rules have exact boundaries

The manager describes the springs as clothing optional while prohibiting visible nudity from Forest Road 19. Alcohol and pets are prohibited at the site; service animals have controlled-access requirements. Open hours end at 10 p.m., not the archive's assumed sunset cut-off.

A maintained site can still have fire and winter hazards

The 2018 fire affected the area; current guidance warns about loose rock, debris flows, flooding and weakened trees. Road 19 is not maintained for snow and ice. Use legal parking and a land-based fallback, and do not convert descriptive pool temperatures or depths into a present health or safety measurement.

Plan Your Visit

Parking & Access

Confirm the entrance, parking arrangements, and legal access with the land manager. A map pin does not establish a public right of access. Follow posted routes and never block gates or driveways.

Regulations & Fees

Clothing optional at the pools does not permit visible nudity from Forest Road 19. No alcohol or pets at the hot springs; service animals must be leashed and controlled. No nighttime use or campground transfer. Public park access does not necessarily include permission to swim. Respect private property and posted restrictions.

Seasonality & Flow

Water conditions can change quickly. This listing does not provide a current safety or water-quality assessment. Check official alerts and avoid entering water when conditions or permission are uncertain.

What to Bring

Bring sturdy water shoes to protect your feet on rocks and slippery surfaces. A waterproof dry bag keeps your phone, keys, and valuables safe. Pack a quick-dry towel, sun protection, and drinking water - never drink from the natural water source.

Nearby Facilities

Frequently Asked Questions About Mckenzie River East Swimming Holes

Are Terwilliger and Cougar Hot Springs different places?

They are names used for this same managed hot-spring destination. Cougar Reservoir is a separate water body with different access.

What is the current published soaking fee?

The Forest Service lists $12 per person per two hours for ages 12 and older, with no passes honored. Confirm the rate and payment arrangement before travel.

Does the old 2014 upper-pool closure still apply?

The current Forest Service page is marked open and describes four pools. The old closure is not a current operating notice; obey new on-site restrictions.

Can we go nude on the road or bring dogs to the pools?

No. Clothing-optional pool use does not permit visible nudity from Road 19, and pets are prohibited at the site. Controlled service-animal provisions are separate.
