Hagg Lake Trail is a 13.4-mile loop in Scoggins Valley Park/Henry Hagg Lake in Oregon, on county land. The route rises from about 365 feet to a high point of 419 feet, with a total elevation gain of 602 feet. The trail is rated hard, and the steepest stretch comes at about 3 miles in, where the grade reaches 18 percent. Summer is the most comfortable time to go. Typical averages from a nearby weather station in Forest Grove show July and August highs around 81 to 82°F with only about three wet days a month, while winter months bring highs in the mid-40s and rain on most days. Bikes are allowed on the trail, but horses are not. The loop makes a full day on foot, and the route is long enough to plan around. Paddlers can find Scoggins Creek about 2.4 miles away and the Tualatin River about 3 miles away. Hikers can also reach the Emerald Necklace Trail, about 5.3 miles off, and Thatcher Park Trails, about 6.1 miles away.
