Tucked away in the stunning Willamette National Forest, Clear Lake is one of Oregon’s hidden gems. This crystal-clear lake is not only breathtakingly beautiful but also holds the title of one of the clearest and most pristine lakes in the state. Its clarity is so remarkable that, on a calm day, you can see ancient submerged trees resting at the lake's bottom.

Clear Lake spans about 148 acres, with depths reaching up to 175 feet in some places. Its clarity is because it’s fed entirely by underground springs, resulting in exceptionally clean water that maintains a cool temperature year-round. This lake is one of the purest in Oregon, with visibility extending to an impressive 100 feet or more. The water's cool temperatures prevent algae growth, keeping the lake's pristine condition intact.

Visitors flock to Clear Lake for its serene beauty and the variety of outdoor activities it offers. Kayaking and canoeing are popular pastimes here as the lake's tranquil waters provide a perfect environment for paddling. For those who prefer to stay on land, fishing is a favorite activity at Clear Lake. Anglers can expect to catch rainbow trout and brook trout, adding to the lake's appeal for a quiet day of fishing.

If you’re a fan of hiking, you’re in for a treat. The Clear Lake Loop Trail is a 5.5-mile path that circles the lake, offering stunning views of the water and the surrounding forest. This easy-to-moderate trail winds through beautiful woods and along the shoreline, giving you plenty of opportunities to pause and enjoy the lake's beauty from different vantage points. For those wanting a shorter stroll, there are smaller trails around the area that are just as enjoyable.

Another way to explore the lake is to rent rowboats or kayaks from the Clear Lake Resort on its northeastern shore. Rentals are available seasonally, allowing visitors to enjoy the water without bringing their own equipment. If you plan on spending more time at the lake, the resort also offers charming cabins for rent, providing a cozy place to stay after a day of adventure.

Access to Clear Lake is free, making it an affordable destination for families and solo travelers. However, if you choose to rent boats or equipment from Clear Lake Resort, there are fees associated with those rentals. Prices are typically reasonable and vary depending on the type of boat and the duration of use. Parking is available near the resort and there may be a nominal fee, especially during peak seasons, so it's always a good idea to check the resort’s website or contact them for the most up-to-date information.

Clear Lake is a stunning destination for those looking to experience Oregon’s natural beauty in a peaceful, unspoiled setting. Whether you're paddling across its glassy surface, hiking the trails, or simply soaking in the serenity, a visit to Clear Lake is bound to leave you refreshed and inspired.

Need some new hiking boots? I love the ones at REI. And if you want to start hiking, make sure you read more about the Clear Lake Loop Trail.
