The Lopez Village loop from Hummel Lake Preserve offers a serene escape into Lopez Island's natural beauty. This easy 2.2-mile (3.5 km) hike guides you through tranquil cedar forests and open fields, eventually leading to the peaceful shores of Hummel Lake. You'll enjoy a mix of lakeside views and shaded woodlands, with a narrow footpath winding through second-growth forest, though be mindful of exposed roots and some short, steep sections. It's a perfect choice for a quick, restorative walk, taking approximately 55 minutes with only 93 feet (28 metres) of elevation gain.
Parking is available at the Hummel Lake Preserve trailhead, making access straightforward. While the preserve itself is quite accessible, the longer forest trails feature uneven terrain, so it's best suited for those comfortable with natural footpaths. Keep in mind that a direct, dedicated hiking loop to Lopez Village isn't explicitly defined, so connecting to the village's amenities might involve walking along island roads. This trail is enjoyable throughout the year, offering a quiet retreat from the everyday.
Hummel Lake Preserve is notable for its ecological significance and successful community-led restoration efforts, transforming previously logged areas into thriving wildlife habitats. It's an excellent spot for birdwatching, with a rare forested bog bordering the lake's eastern shore, and provides a chance to experience Lopez Island's largest freshwater lake. This trail offers a peaceful alternative to more strenuous island hikes, focusing on natural tranquility and local conservation success.
