This route was planned by komoot.
This trail is considered difficult for jogging. It features steep terrain, a narrow path, and can be rocky and muddy in places. You'll encounter tree roots and talus slopes, and some sections may require route-finding skills where the tread is less defined. It's definitely not a 'walk in the park' and requires good physical condition and attention to footing.
The terrain is varied and challenging. It zigzags through old-growth forests with hemlock and fir, often alongside Tenas Creek. Further along, it opens into an avalanche slope with boulder fields. Footing can be tricky due to roots, rocks, and potentially muddy sections. The destination, Boulder Lake, is nestled within metamorphic cliffs.
Along the route, you'll pass by Tenas Creek, which features a twin waterfall around the 1-mile mark. The trail also offers breathtaking views from an avalanche slope with boulder fields. The highlight of the journey is reaching Boulder Lake itself, a striking azure lake. You can also enjoy a View of Spada Lake.
Given its distance of nearly 22 km and difficult rating, jogging the entire Boulder Lake Trail typically takes around 3 hours and 6 minutes. However, individual times will vary based on fitness level and trail conditions.
Specific permit and fee requirements for the Boulder Lake Trail and the Morning Star Natural Resources Conservation Area can vary. It's always best to check the official website of the managing authority (e.g., US Forest Service or Washington State Parks) before your visit to confirm any current regulations, entrance fees, or parking passes needed.
Information regarding specific parking areas for the Boulder Lake Trail is not detailed in the provided sources. For trails of this nature, parking is typically available at a designated trailhead. It is advisable to research the exact trailhead location and parking availability before your trip, as conditions and access points can change.
Public transport options to reach the trailhead for the Boulder Lake Trail are generally limited or non-existent due to its remote location within the Morning Star Natural Resources Conservation Area. Access is typically by private vehicle.
The provided information does not explicitly state whether dogs are allowed on this specific Boulder Lake Trail in Washington. Regulations for pets can vary by conservation area and specific trail. It's recommended to check with the Morning Star Natural Resources Conservation Area's official guidelines regarding pet policies before bringing your dog.
The best time to jog this trail is generally during the drier months, typically late spring through early fall. Due to potentially muddy sections and snow that can linger at higher elevations, visiting outside of these times might present additional challenges. There is also little shade in some open avalanche slope sections, so consider this during warmer periods.
Yes, the route incorporates sections of several official trails. You will primarily be on the Boulder Lake Trail, but it also passes through parts of the Greider Lakes Trail and the Greider/Boulder Lakes Trail.
Given the trail's difficulty and length, you should bring plenty of water, appropriate trail running shoes with good grip, navigation tools (like a map and compass or a GPS device), layers of clothing for changing weather, snacks, and a first-aid kit. Due to potential route-finding challenges, it's wise to download the komoot tour offline.
