Crestline Sidewinder Loop Trail is a 9.6 mile moderately trafficked loop trail located near Boise, Idaho that features beautiful wild flowers and is rated as moderate. The trail offers several activity options and is best used from March until October. Dogs will also be able to use this trail.
Crestline is among my personal favorite loops, which I recently realized joins with all the riparian trail that leads up to the Upper Hull’s Gulch area. It’s a lovely hike, just bring a lot of water in the summer and look out for cyclists!
Good overall hike but not really a great area for birding. Very few varieties and appearances on the day I was there. This trail seems better for mountain biking than hiking and that’s mostly what you’ll see. It really is a good length and relatively pretty if you want desert scenery. There exists a really small forested area at the start. The process level is most likely near easy but with a route for enough time to discourage young children. The inclines are incredibly mild compared to other moderate rated desert trails like Harrison Hollows.
Great trail system with access from a number of different starting points. Strongly suggest. Great for all ability levels, according to your options obviously. Best trail for dog owners! The Military Reserve posseses an off leash dog park and many trails are off leash. Take pleasure in the wildflowers in April & May! Among the need to do trails inside the Boise Foothills, Sidewinder is really a nice climb, great view, and a fun downhill. Somewhat crowded on weekends.
Below are a few recommendations for dynamite hikes, trail-runs and bike rides inside the Boise foothills. The tips result from my trail guides, Mountain Biking in Boise and Boise Trail Guide. It’s essential to focus on the mid- to reduce foothills trails during the early spring. Top of the trails and the Boise Ridge Road continue to be snow-bound. The trails in the mid- to upper foothills, such as the Watchman Trail, remain wet and greasy in some places, so it’s better to wait to allow them to dry completely. Prior to deciding to hit the trails, check out current trail conditions on the Ridge to Rivers website.
Military Reserve Short Loop – 2 miles, lower than an hour hiking time. Easy, using a short hill. Here’s a shorter tour for families and small kids. Start in the Toll Road Trailhead off of Mountain Cove Road. Go up the Toll Road Trail less than a mile to a junction. Go left and ascend to the initial summit of Military Ridge. Turn left and descend on a singletrack trail resulting in Freestone Creek Trail over from the dirt road. Turn left on Freestone and come back to the trailhead.
Seaman’s Gulch Double Loop – 3 miles total. 1 hours hiking time; 30-45 minutes running time; half an hour riding time. Easy. Take Hill Road west in Boise towards the Seaman’s Gulch/Hidden Springs right-hand turnoff. Go right and follow Seaman’s Gulch Way to a nice paved parking area and restroom alongside a big water tank. Take the Valley View Trail #111 to the right, and then take the first left on Trail #110 to Phlox Trail #112, turn left and return to the trailhead to get a one-mile short loop. Now return on Valley View, and keep going out to the true “valley view” viewpoint provided by the trail, hanging above the Boise Valley. The trail loops around to fknihd and returns for the trailhead.
Cross-Foothills Ride (Intermediate; strenuous in places) – 10 miles. 2 hours riding time. Strong intermediate. Today, I rode approximately the Corrals Trail (trailhead is 1.8 miles north of Curling Drive on Bogus Basin Road), rode Corrals to Corrals Summit, then rode downhill on Corrals and Trail #1 over to Hulls Gulch. Then I took Crestline Sidewinder Loop Trail to Military Reserve, and dropped out on the Freestone Creek Trail in Military Reserve near Fort Boise. The most difficult part of the ride is climbing to Corrals Summit (3 miles uphill from trailhead, 1,200 feet of vertical gain). Then it’s mostly downhill to Military Reserve, with some uphill sections in the middle. Fun ride! Hardy mountain trail runners would enjoy that route too.
Crestline-Hulls Loop – 7.25 miles. Moderate. 2.5 hours hiking time; 1.5 hours running time; 1.25 hours riding time. Intermediate. Start from Camelsback Park in Boise on N. 13th. Get the trailhead behind the tennis courts. Climb on Owls Roost and Kestrel to Crestline. Follow Crestline towards the Hulls Gulch Junction. Turn left and descend on Hulls Gulch. It’s rocky and uneven in places. When you get to the 8th Street trailhead from the Foothills Learning Center, turn right, cross 8th Street, and finish the ride on Red Fox Trail, which leads you back to Camelsback Park.
Variations on Crestline-Hulls Loop – Advanced. Ride the loop in reverse, or climb Hulls. It’s a challenge, but fun! Another favorite of mine would be to start at Camelsback Park, climb Hulls towards the Crestline junction, ride Crestline back to the Sidewinder trailhead, climb Sidewinder, fall Trail #4 towards the Hulls Crestline junction, and descend Hulls and Chickadee Ridge back to Camelsback.
