Owyhee Gravestone

The highest point in the Owyhee Mountains is also an Idaho County Highpoint (Owyhee County).  The mountain offers an easy hike and relatively close escape from the greater Boise region (Treasure Valley).  Depending on the time of year, you can make an outing on Hayden Peak as easy or difficult as you like and also include 4 other peaks in the range in one outing. Superb mountain biking can be found on the numerous jeep roads in the area.   

The region surrounding the peak is rich with mining history with remnants of one type or another nearly everywhere.  Nearby Silver City offers a taste of a  late 1800's mining town without the commercialism of other living ghost towns.  Situated just north of Hayden Peak is War Eagle Mountain, the site of many battles amongst miners and management, Indian raids, and more recently a radio antenna.  Although these mountains have been the victims of unregulated extraction throughout their recent history, one can easily find complete solitude in one of the most remote sections of the lower 48 states.  

Hayden Topo with Route

Trails / Routes 

North Approach via Lineham Flat Road- This route can usually be tailored to your time frame and endurance level.  From the Silver City Stage Road, take the Lineham Flat Road south as it snakes just east of War Eagle Mountain, just south of Turntable Mountain, and cuts up the western side of Hayden Peak.  An excellent stop is at a pioneer cemetery on the northeast side of War Eagle Mountain.  The graves are dated from the 1800's and many are marked "unknown". A good option is to mountain bike much of the approach, and hike to the summit from the junction on the west side of the peak. Mostly Class 1 with some Class 2 hiking near the summit.

From the Lineham Road turnoff to the summit: 8 miles and 3200 feet gain (one way)

From the Sinker Creek turnout to the summit: 16.1 miles and 7050 feet gain (one way)

Snow often lingers on this approach well into May and even June in some years.  The Stage Road is subject to washouts and variable conditions and 4WD may be required.  Utilizing a mountain bike is a viable option for this specific route.

Hayden Peak

North Approach via Scotch Creek and Thomas Lakes- This approach involves a more complicated connection of jeep roads and ends with a Class 3+ steep ascent up the north side of the peak. Early season can offer a finish on steep snow or you can scramble on the small rock outcropping just east of the summit.  The snow chutes between the rock outcroppings appear to be potential areas to explore for future reference.

Leave the Silver City Stage Road at the Scotch Creek turnoff (marked with an "Access Yes" sign) and follow a steep jeep road south through the Sinker Tunnel past Oro Fino Gulch.  Pass numerous mining remnants and follow the steep road east and then north. Near the Burnham Flat area you can ascend the steeper north side.

From the Scotch Creek turnoff to the summit: 6.2 miles and 4640 feet gain (one way)

From the Sinker Creek turnout to the summit: 10.4 miles and 5340 feet gain (one way)

Snow often lingers on this approach even longer, often into June in many years.   Utilizing a mountain bike is a viable option for the first portion of the route. This route offers more hiking and scrambling. Private property issues may exist on this approach, but can be easily avoided.  Hiking through on foot or bike seems rather innocuous compared to the mining, off-roading, and destructive grazing that has occurred here.

Owyhee Wildflowers

South Approach via Quicksilver Mountain- From just west of the Toy Pass area, follow a series of jeep roads along the major ridgeline to the summit (Class1-2)  

From the Toy Pass area to the summit: 12.7 miles and 5100 feet gain (one way)

While this approach is generally longer, it offers a more snow free access, thus a longer season.  Utilizing a mountain bike is not a great option here due to some brief ridge hiking away from the jeep roads.. Some private property issues exist just west of the ridge and there are more active residents in the area.

Another possibility is from the Jordan Creek Area on the west side of the peak.

Getting There

Hayden from near Toy Pass

North Approaches:  From ID-78, just south of Murphy, follow the signed Silver City Road southwest through a narrow canyon on a highly variable dirt road.  Some years it can driven easily by a sedan. Other years, like 2006, a 4WD and/or high clearance will be required.  The Scotch Creek turnoff is 15 miles from ID-78. The Lineham Flat turnoff is 18.7 miles from ID-78

South Approach:  From ID-78, drive south of Murphy for 13 miles and turn off to Oreana. Follow the Bachman Grade (Triangle Road) up and just over Toy Pass after 14 miles.

Conditions and Season

New York Summit

Conditions in the Owyhee Mountains varies greatly. Although this is considered a desert mountain region, the peaks may accumulate 3 to10 feet over the winter.  Temperatures can be mild  in the winter and with the open slopes and prevalent wind, avalanches are not uncommon here.  The Silver City Newspaper of the 1800's was called the Owyhee Avalanche. Summers can be downright hot, like much of the canyons below.

From late December to March many of the roads are snowed in.  From March to June snow drifts may linger, but this time frame offers the greatest chance of solitude as the off road vehicles are not out generally. Summer time and especially summer weekends are very crowded (by Idaho standards) and Fall brings out the "hunters".  Early winter may offer a good time to explore also.  If you don't mind hiking or biking over a big snow drift, you'll most likely be alone past that point as the Off Roaders don't wander very far from their "machines".
