Boulder Lake — Olympic National Park

Boulder Lake Campground is a primitive backcountry site with minimal amenities. There are no developed facilities such as potable water, flush toilets, or picnic tables. Campers should be prepared to be self-sufficient by packing in all necessary supplies and packing out all waste. The campground offers a true wilderness experience, so plan accordingly with proper food storage containers, water filtration systems, and camping gear suitable for remote locations.

Boulder Lake offers excellent opportunities for fishing, swimming, and photography in a pristine alpine setting. Hiking is a primary activity, both to reach the lake (approximately 7 miles from the road) and to explore the surrounding wilderness areas. Wildlife viewing is rewarding, with various birds and small mammals inhabiting the area. For the adventurous, there are opportunities for backcountry exploration and stargazing in this remote location far from light pollution.

The optimal time to visit Boulder Lake Campground is during the summer months, typically from late June through September. This period offers the most favorable weather conditions and trail accessibility. Be aware that early season visits may encounter snow at higher elevations, while late September brings cooler temperatures. The campground is most accessible when the snow has melted from the trails. Always check current trail and road conditions with Olympic National Park before embarking, as the access road to the trailhead has been closed in the past, adding additional hiking distance.

No formal reservation system exists for Boulder Lake Campground. This is a first-come, first-served backcountry camping area within Olympic National Park. However, you will need to obtain a wilderness camping permit from the Olympic National Park Wilderness Information Center before your trip. These permits may have quotas during peak season, so it's advisable to secure them well in advance of your planned visit.
