Trentwood Trailhead

News! The Trentwood Trailhead will open to the public on Saturday, November 20th! 
The Trentwood Trailhead (informally known as Etter Ranch), when completed, will add a third trailhead to Antoine Peak Conservation Area, providing direct access from the City of Spokane Valley less than 1/4 mile from Trent Avenue. The trailhead is planned to have 20 passenger vehicle stalls as well as truck and trailer parking for those with horses. As with our Phillips Creek and Glenrose trailheads, Trentwood is planned to feature paved parking, dark-sky certified lighting, native landscaping, fencing, a webcamera and portable restroom. In addition to these features, the trailhead is also planned to include a separated parking area for horse trailers.
