If you're looking for a good day-hike to escape the heat in St. George, this Pine Valley trail offers some relief. The day we hiked, we only met one group of three at the trailhead and later in the hike, a solo local hiker. She told us that the switchbacks had been lengthened to reduce the grade and make the climb easier. This lengthening has added 0.6 miles to the hike, making the total RT distance 7.3 miles. Our actual moving time was 4.5 hours. It was a warm sunny day in late June, with the temperature hovering in the high 80's. If you're hiking this trail in the summer, take plenty of water and take it slow and it will make for a pleasant day hike. Views into Pine Valley open up as you climb higher. At the top of the climb, bear left. The 200 foot drop into Hop Canyon is worth the effort. Although, no water was running, the canyon does offer a good shaded lunch spot with numerous stands of tall aspens. After climbing out of the canyon, the return trip to the trailhead is quick. I'd recommend wearing sturdy hiking shoes, since the trail has many rocky stretches.
