Crestline Sidewinder Loop Trail is a 9.6 mile moderately trafficked loop trail located near Boise, Idaho that features beautiful wild flowers and it is rated as moderate. The trail offers several activity options and is best used from March until October. Dogs can also be able to utilize this trail.
Crestline is one of my favorite loops, that i recently realized joins with the riparian trail which leads up into the Upper Hull’s Gulch area. It’s a lovely hike, just bring a lot of water in the summertime and be aware of cyclists!
Good overall hike but not really a great area for birding. Only a few varieties and appearances on the day I used to be there. This trail seems better for biking than hiking and that’s mostly what you’ll see. This is a good length and relatively pretty if you want desert scenery. You will find a very small forested area in the beginning. The challenge level is probably near easy though with a route long enough to deter small kids. The inclines are extremely mild in comparison to other moderate rated desert trails like Harrison Hollows.
Great trail system with access from several different starting points. Highly recommend. Great for all ability levels, based on your choices of course. 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 must do trails in the Boise Foothills, Sidewinder is really a nice climb, great view, along with a fun downhill. A bit crowded on weekends.
Here are a few recommendations for dynamite hikes, trail-runs and bike rides inside the Boise foothills. The guidelines come from my trail guides, Biking in Boise and Boise Trail Guide. It’s vital that you focus on the mid- to reduce foothills trails in early spring. Top of the trails and also the Boise Ridge Road continue to be snow-bound. The trails within the mid- to upper foothills, like the Watchman Trail, are still wet and greasy in a few places, so it’s advisable to wait to allow them to dry completely. Before you decide to hit the trails, have a look at current trail conditions on the Ridge to Rivers website.
Military Reserve Short Loop – 2 miles, lower than an hour hiking time. Easy, having a short hill. Here’s a shorter tour for families and small kids. Start in the Toll Road Trailhead off of Mountain Cove Road. Rise the Toll Road Trail under a mile to some junction. Go left and climb up to the initial summit of Military Ridge. Turn left and descend on the singletrack trail ultimately causing Freestone Creek Trail over from the dirt road. Turn left on Freestone and go back to the trailhead.
Seaman’s Gulch Double Loop – 3 miles total. 1 hours hiking time; 30-45 minutes running time; thirty minutes 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 Road to a good paved parking area and restroom next to a large water tank. Take the Valley View Trail #111 off to the right, and after that go ahead and take 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 back on Valley View, while keeping going out to the real “valley view” viewpoint supplied 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. two 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 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 toughest 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 between. Fun ride! Hardy mountain trail runners would enjoy that route also.
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. Whenever you get to the 8th Street trailhead through the Foothills Learning Center, turn right, cross 8th Street, and finish the ride on Red Fox Trail, which leads you to Camelsback Park.
Variations on Crestline-Hulls Loop – Advanced. Ride the loop in reverse, or climb Hulls. It’s difficult, 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, come down Trail #4 for the Hulls Crestline junction, and descend Hulls and Chickadee Ridge to Camelsback.
