PARK UPDATE

Spring 2026

🚧 Ashton-Tetonia Trail Paving Project Update 🚧
Construction continues to move forward on the Ashton-Tetonia Trail! Please plan ahead before visiting the trail, as several parking areas and trail sections are currently closed due to construction.
⚠️ Current Closures
Parking Areas
• Marysville Parking Area – Closed until further notice.
• Lamont Parking Area – Closed while crews prepare the parking lot for paving.
• Judkins Parking Area – Closed while crews prepare the parking lot for paving.
• Felt Parking Area – Closed while crews prepare the parking lot for paving.
• Tetonia Parking Area – Closed while crews prepare the parking lot for paving.
❗All closed parking areas are impassable. Please do not drive around barricades or enter construction zones.
Trail Closures
• The Ashton to Fall River Trestle and on to 1100 north section of the trail is closed. Paving will begin at the Fall River Trestle and work back toward Ashton. Once paving is complete, this section will remain closed for approximately two additional weeks while crews complete the trail shoulders. We anticipate approximately two weeks for paving, followed by two weeks for shoulder work, with this section expected to reopen by mid-August, weather permitting.
• The Tetonia Parking Area to Highway 33 section of the trail is closed while crews prepare the trail for paving.
🚗 Parking & Trail Access
✅ The Grainville Parking Area and France Parking Area are currently the only parking lots open to the public.
The following trail sections remain open during construction:
• Judkins to Lamont (Please note that both parking areas are closed. Access is available only from alternate locations.)
• Grainville to France (Accessible from the Grainville Parking Area.)
If you choose to access the trail from another location, parking along roadways is at your own risk. Please park safely, obey all traffic laws, and do not block driveways, gates, or emergency access.
🚧 For everyone’s safety, please avoid all active construction areas and give our crews the room they need to work safely and efficiently. The sooner they can complete the work safely, the sooner we can reopen the trail and parking areas for everyone to enjoy.
We’ll continue to share updates on construction progress, temporary closures, and reopening dates as work progresses.
Thank you for your patience, understanding, and continued support as we work to improve the Ashton-Tetonia Trail!
 

The Ashton Visitor Center is open 7 days per week, staffing dependent. 

Please be mindful of your speed while recreating on the Ashton-Tetonia Trail to ensure a safe and enjoyable visit for all. Class 3 e-bikes, motorized ATVs, OHVs, & vehicles are not permitted on the trail.

Special Projects

Ashton-Tetonia Trail Paving Project The Idaho Department of Parks and Recreation plans to pave the Ashton-Tetonia Trail, Some work will begin this fall, with the majority scheduled for next year. Seeking to attract more users and to decrease the annual maintenance of the trail, the department secured federal funding to pay for the $3 million project. Based on the experience with the Coeur d’Alene Parkway and the Trail of the Coeur d’Alenes in North Idaho, the department expects the paving will be beneficial to the area’s economy. Project Details
  • Construction:

-3.56 miles from Ashton to Falls River Trestle

-0.92 miles from Judkins Parking Lot toward Bitch Creek Trestle

-0.94 miles from Tetonia Parking Lot to Highway 33

-Paving 5 parking areas for improved access

-Installing 14 upgraded gates

-Adding new trail signage for easier navigation

  • Length: Paving 5.5 miles of trail
  • Width: 8-10 feet
  • Thickness: 3 inches of asphalt over a 9 inch base layer of compacted material.
Funding comes from an EDA federal grant, which is designed for economic development. An economic impact study showed that the Coeur d’Alene Parkway and Trail of the Coeur d’Alenes contribute $1.4 million and $1 million, respectively, each year to the local economy. The benefits of a paved trail include a smooth surface for cyclists, parents with baby strollers, and for those with wheelchairs or other adaptive equipment. Asphalt will last many years with relatively low maintenance, alleviating the need to weeding, grading and other maintenance, which experience has shown to be a challenge.
