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 a number of activity options and is best used from March until October. Dogs can also be able to use this trail.
Crestline is one of the best loops, that i recently realized joins with all the riparian trail which leads up in to the Upper Hull’s Gulch area. It’s a beautiful hike, just bring lots of water in the summertime and be aware of 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 biking than hiking and that’s mostly what you’ll see. This is a good length and relatively pretty if you like desert scenery. There exists a really small forested area at the start. The process level may well be near easy but with a route long enough to deter young children. The inclines are extremely mild when compared with other moderate rated desert trails like Harrison Hollows.
Great trail system with access from many different starting points. Highly recommend. Beneficial to all ability levels, based on your alternatives obviously. Best trail for dog owners! The Military Reserve comes with an off leash dog park and most trails are off leash. Take pleasure in the wildflowers in April & May! One of the need to do trails within the Boise Foothills, Sidewinder is a nice climb, great view, and a fun downhill. Somewhat crowded on weekends.
Here are a few strategies for dynamite hikes, trail-runs and bike rides in the Boise foothills. The ideas come from my trail guides, Biking in Boise and Boise Trail Guide. It’s vital that you focus on the mid- to decrease foothills trails during the early spring. Top of the trails and the Boise Ridge Road remain snow-bound. The trails within the mid- to upper foothills, like the Watchman Trail, continue to be wet and greasy in a few places, so it’s better to wait for them to dry completely. Before you decide to hit the trails, take a look at current trail conditions on the Ridge to Rivers website.
Military Reserve Short Loop – 2 miles, under one hour hiking time. Easy, using a short hill. Here’s a shorter tour for families and small kids. Start on the Toll Road Trailhead from Mountain Cove Road. Rise the Toll Road Trail under a mile to your junction. Go left and climb up towards the initial summit of Military Ridge. Turn left and descend over a singletrack trail resulting in Freestone Creek Trail over by 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; 30 minutes riding time. Easy. Take Hill Road west in Boise to the Seaman’s Gulch/Hidden Springs right-hand turnoff. Go right and follow Seaman’s Gulch Path to a great paved parking area and restroom next to a large water tank. Go ahead and take Valley View Trail #111 to the right, and then take the first left on Trail #110 to Phlox Trail #112, turn left and come back to the trailhead for any one-mile short loop. Now go back on Valley View, whilst keeping going to the real “valley view” viewpoint offered by the trail, hanging above the Boise Valley. The trail loops around to fknihd and returns to the trailhead.
Cross-Foothills Ride (Intermediate; strenuous in places) – 10 miles. two hours riding time. Strong intermediate. Today, I rode up to 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 up to Hulls Gulch. I Then 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 portion 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 a few uphill sections between. 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. Discover the trailhead behind the tennis courts. Climb on Owls Roost and Kestrel to Crestline. Follow Crestline to 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 a challenge, but fun! Another favorite of mine is to start at Camelsback Park, climb Hulls to 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 returning to Camelsback.
