Run It Both Ways: Discovering Stimpson Family Nature Reserve

A hidden Pacific Northwest gem in Bellingham, Washington—where old-growth forest, quiet ponds, and 400-year-old Douglas Firs offer a new perspective with every direction you run.

At LLRULE, we're all about the adventure—from ski to sea and everything in between. Today, we're taking you to one of our favorite hidden gems in the Pacific Northwest: Stimpson Family Nature Reserve, just outside Bellingham, Washington. If you're looking for a trail that feels like stepping into another world, this is it.

Nestled along Lake Louise Road, this 400-acre arboreal sanctuary is the kind of place you stumble upon and never forget. Old-growth forest. Moss-draped trees. Douglas Firs that have been standing for over 400 years. It's a living, breathing piece of Pacific Northwest history—and it's waiting for you to run through it.

The trail winds through dense forest canopy, moss-covered trees, and fields of ferns.

The Main Loop: 3.2 Miles of Pure Forest Running

The Main Loop is where most runners start—and honestly, it might be all you need. At 3.2 miles with about 300 feet of elevation gain, it's the kind of moderate challenge that keeps your legs honest without breaking you down. The trail takes you through dense forest, past the Beaver Pond Viewpoint (the first 0.1 miles is fully accessible gravel), and deeper into terrain that feels untouched by time.

The surface varies—packed dirt, roots, soft forest floor. You'll duck under low-hanging branches, hop over fallen logs, and find yourself completely immersed in the kind of quiet that only exists in places like this. No traffic noise. No distractions. Just your footfalls and the forest.

"Run it forward one day. Run it backward the next. Same trail—completely different experience."

Run It Both Ways: A New Perspective Every Time

Here's the thing about Stimpson that we've come to love: direction changes everything. Run the Main Loop clockwise and you'll climb early, hitting the elevation in the first half before cruising back down. Run it counterclockwise and the experience flips—you'll ease into the terrain before tackling the climb on tired legs.

It's the same trail, but it feels completely different depending on which way you go. The views shift. The light hits different. What was a descent becomes a climb, and what you missed going one way suddenly reveals itself going the other.

We recommend running it both ways—maybe not on the same day—but definitely on consecutive visits. You'll see things you missed the first time. You'll feel the terrain in a new way. And you'll understand why runners keep coming back to trails like this, even when they "know" every inch of them.

Geneva Pond—an optional spur trail that adds an extra mile to your run.

Add a Mile: The Geneva Pond Loop

Feeling strong? Take the spur trail off the Main Loop to Geneva Pond. It's an additional 2.0-mile loop that circles a quiet, reflective pond tucked away from the main route. The terrain is similar—moderate, forested, peaceful—but the vibe is different. Fewer footprints. More solitude. The kind of place where you might catch a glimpse of a beaver or deer if you're moving quietly enough.

Add it to your run for a solid 5+ mile day. Or save it for a separate trip when you want to explore something new without committing to a full adventure. Either way, it's worth the detour.

Winter transforms the reserve into a quiet, snow-covered wonderland—a completely different running experience.

Every Season. Every Condition.

Stimpson isn't just a summer destination. In the fall, the forest floor lights up with golden hues and fallen leaves cushion every step. In winter, a fresh layer of snow transforms the reserve into something out of a storybook—quiet, pristine, and utterly peaceful. Spring brings the return of green, with ferns unfurling and the forest coming back to life.

The trail conditions change, but the experience remains equally rewarding. Just adjust your footwear, layer up, and go. That's the beauty of trails like this—they give you something new every time you show up.

Why We Love It

Stimpson Family Nature Reserve is the kind of place that reminds you why you started running trails in the first place. It's not about the pace or the PR. It's about being out there—surrounded by trees that have been standing since before your great-great-grandparents were born, running through a landscape that demands nothing from you except presence.

It's a place to explore. To slow down. To push yourself when you want to and ease off when you don't. Run it forward. Run it backward. Add the extra mile or keep it short. There's no wrong way to experience a trail like this.

If you find yourself in Bellingham, Washington—or you're looking for a reason to make the trip—put Stimpson on your list. It's the kind of hidden gem that won't stay hidden for long.
