Tunnel is an easy, out-and-back hike of about 1.6 miles in the Mt. Shasta Ranger District of Shasta-Trinity National Forest in California. The trail starts near the low point of 4,060 feet and climbs to a high of 4,248 feet, a rise of 178 feet one way. Summer is the most comfortable time to go. Typical averages from a nearby weather station at Mt. Shasta show July and August highs in the mid-80s and only about two wet days a month, while winter brings highs in the mid-40s and roughly 13 wet days a month. The trail is on natural surface and bikes are allowed. It is open year-round, and the surrounding area has several other places to visit. My Trail and Stump are both within a third of a mile. Byron's Boulder, a climbing area, is about 1.4 miles away, and Mcbride Springs Campground is about 1.9 miles off.
