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 it is best used from March until October. Dogs are also able to utilize this trail.
Crestline is among the best loops, that i recently realized joins using the riparian trail which 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 however, 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. This is a good length and relatively pretty if you appreciate desert scenery. There is a very small forested area at the start. The process level is probably near easy though with a route long enough to discourage small children. The inclines are extremely 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. Beneficial to all ability levels, based on your alternatives obviously. Best trail for dog lovers! The Military Reserve has an off leash dog park and most trails are off leash. Enjoy the wildflowers in April & May! One of many have to do trails within the Boise Foothills, Sidewinder is really a nice climb, great view, along with a fun downhill. A little crowded on weekends.
Here are some strategies for dynamite hikes, trail-runs and bike rides inside the Boise foothills. The tips come from my trail guides, Mountain Biking in Boise and Boise Trail Guide. It’s essential to focus on the mid- to lower foothills trails during the early spring. The top trails and the Boise Ridge Road are still snow-bound. The trails within the mid- to upper foothills, including 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, take a look at current trail conditions on the Ridge to Rivers website.
Military Reserve Short Loop – 2 miles, under 1 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 less than a mile to your junction. Go left and climb up for the initial summit of Military Ridge. Turn left and descend on a singletrack trail resulting in Freestone Creek Trail over through 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; half an hour riding time. Easy. Take Hill Road west in Boise for the Seaman’s Gulch/Hidden Springs right-hand turnoff. Go right and follow Seaman’s Gulch Path to a nice paved parking area and restroom next to a sizable water tank. Consider the Valley View Trail #111 to the right, then take the first left on Trail #110 to Phlox Trail #112, turn left and come back to the trailhead for a one-mile short loop. Now return on Valley View, whilst keeping going out to the actual “valley view” viewpoint provided by the trail, hanging over 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 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 toughest 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 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. Find 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. When you reach 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 challenging, but fun! Another favorite of mine is always to start at Camelsback Park, climb Hulls to the Crestline junction, ride Crestline returning to the Sidewinder trailhead, climb Sidewinder, come down Trail #4 to the Hulls Crestline junction, and descend Hulls and Chickadee Ridge returning to Camelsback.
