Crestline Sidewinder Loop Trail is actually 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 it is best used from March until October. Dogs can also be able to use this trail.
Crestline is among my favorite loops, which I recently realized joins with the riparian trail that leads up in to the Upper Hull’s Gulch area. It’s an attractive hike, just bring plenty of water in the summertime and look out for 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 mountain biking than hiking and that’s mostly what you’ll see. It really is a good length and relatively pretty if you appreciate desert scenery. There is a really small forested area in the beginning. The task level may well be near easy though with a route for enough time to discourage young children. The inclines are very mild compared to other moderate rated desert trails like Harrison Hollows.
Great trail system with access from many different starting points. Strongly recommend. Great for all ability levels, based on your alternatives needless to say. 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! One of many need to do trails inside the Boise Foothills, Sidewinder is a nice climb, great view, as well as a fun downhill. Somewhat crowded on weekends.
Below are a few strategies for dynamite hikes, trail-runs and bike rides within the Boise foothills. The guidelines come from my trail guides, Biking in Boise and Boise Trail Guide. It’s essential to focus on the mid- to decrease foothills trails in early spring. The top trails and the Boise Ridge Road are still snow-bound. The trails in the mid- to upper foothills, like the Watchman Trail, are still wet and greasy in certain places, so it’s better to wait so they can dry completely. Before you hit the trails, have 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 off of Mountain Cove Road. Rise the Toll Road Trail under a mile to a junction. Go left and climb up towards the initial summit of Military Ridge. Turn left and descend over a singletrack trail leading to Freestone Creek Trail over from the dirt road. Turn left on Freestone and return 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 nice paved parking area and restroom close to a sizable water tank. Go ahead and take Valley View Trail #111 to the correct, and then go ahead and take first left on Trail #110 to Phlox Trail #112, turn left and come back to the trailhead for any one-mile short loop. Now return on Valley View, while keeping going out to the real “valley view” viewpoint offered by the trail, hanging higher than the Boise Valley. The trail loops around to fknihd and returns towards 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, and after that rode downhill on Corrals and Trail #1 over 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 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 just a few uphill sections between. Fun ride! Hardy mountain trail runners would enjoy that route as well.
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 towards the Hulls Gulch Junction. Turn left and descend on Hulls Gulch. It’s rocky and uneven in places. When you make it 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 back 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 is to start at Camelsback Park, climb Hulls for the Crestline junction, ride Crestline to the Sidewinder trailhead, climb Sidewinder, come down Trail #4 for the Hulls Crestline junction, and descend Hulls and Chickadee Ridge returning to Camelsback.
