Pine Isle Lake is an easy out-and-back hike of about 1.2 miles in the Flat Tops Wilderness, part of the Blanco Ranger District of White River National Forest in Colorado. The trail rises about 111 feet from a low point of 9,251 feet to a high of 9,389 feet, and it is managed by the Forest Service. The route is natural-surface and allows horses, so it works well for riders. Bikes are not permitted. The trail is open year-round, and the surrounding wilderness makes it a compact outing in a remote corner of the forest. Summer is the most comfortable time to go. Typical averages from a nearby weather station in Yampa, which sits about 1,500 feet lower, show July highs around 79°F with lows near 46°F. Winter is cold, with January highs around 32°F and lows near 7°F. Oyster Lake is about 1.7 miles away, and Mary Loch Lake and Horseshoe Lake are both within about 3.6 miles. For an overnight stay, Marvine Campground is about 5 miles off.
