If you've ever tried to plan gravel biking in Alpine Lakes Wilderness Study Area, you know how overwhelming the options can be.

You'll find yourself on unpaved roads and trails in the National Forests adjacent to the wilderness, offering a unique blend of challenging climbs and rewarding views through diverse forests. Expect routes that range from moderate to difficult, often with significant elevation gains, but always with that stunning backdrop of rugged peaks and sawtooth ridges.

The "The Seals" – Keechelus Lake loop offers a dynamic gravel biking experience through the scenic Snoqualmie Pass region. You'll pedal through lush forested areas and along the captivating shores of Keechelus Lake, where, in the fall, lower water levels reveal the unique rock formations known as "The Seals." The terrain varies from hard-packed gravel on sections of the historic Palouse to Cascades State Park Trail to dirt and some paved segments, providing a constantly engaging ride.

Planning your visit means preparing for a challenging outing. This difficult 33.7-mile (54.3 km) loop involves a substantial 3264 feet (995 metres) of elevation gain, typically taking around 3 hours and 36 minutes to complete. It's a favorite among local gravel bikers for its traffic-free paths, but be ready for a demanding ride that requires very good fitness and advanced skills, especially on climbs and descents.

What makes this route stand out is its blend of natural beauty and historical significance. Integrating parts of the Palouse to Cascades State Park Trail, you might even cross historic trestles. The ever-changing Keechelus Lake, with its seasonal "Seals" visibility, adds a unique natural feature to the mountainous backdrop of the Snoqualmie Pass area, making it a top choice for an adventurous gravel biking day.

Snoqualmie Tunnel – Snoqualmie Tunnel loop from Hyak

Embark on a truly distinctive gravel biking adventure with the Snoqualmie Tunnel loop from Hyak, a moderate 15.9-mile (25.5 km) route that promises an unforgettable experience. The journey's centerpiece is the historic Snoqualmie Tunnel, a 2.3-mile-long passage that's profoundly dark, cool, and damp, offering a unique sensory experience. Outside the tunnel, you'll pedal through varied landscapes of forested areas, river valleys, and past historic trestle bridges, with occasional mountain views, all on a mostly hard-packed gravel surface. This route is a fantastic option for those seeking a memorable ride with gentle grades and plenty of character.

Planning your visit requires attention to detail, especially regarding the tunnel's seasonal closure from November 1st to May 1st. Even in summer, the tunnel's consistent 40-degree Fahrenheit temperature and damp conditions necessitate warm clothing layers. Crucially, you'll need multiple powerful lights – both headlamps and bike lights, along with backups – as the tunnel is completely unlit. Parking is available at the Hyak trailhead, and an early start is advisable during busy periods to secure a spot and enjoy the trail.

This loop is an integral part of the broader Palouse to Cascades State Park Trail, showcasing a significant piece of railroad history. The Snoqualmie Tunnel itself holds the distinction of being the nation's largest tunnel open to non-motorized traffic, making it a notable landmark. Its gentle 698 feet (213 metres) of elevation gain over 1 hour and 26 minutes makes it suitable for beginner gravel bikers and families, offering a high-reward experience without demanding extreme fitness.

The Palouse to Cascades State Park Trail is a long gravel route across Washington, great for bikepacking or long rides. The Snoqualmie Tunnel is a must—dark, damp, and fun (bring lights). Expect wind and remote stretches, so pack water and gear. Riding over trestles and through changing landscapes keeps things interesting the whole way.

I am always amazed how different this lake looks in the spring (full) versus the fall (almost empty). Those "Seals" are visible in the fall but then go for a long swim in the winter and spring...

The State Park is on the West shore of Lake Easton - very nice campground. An excellent overnight spot in the Spring/Summer/Fall when doing the Palouse to Cascades trail. Worth looping around the lake to see it from all sides and experience the tunnel and bridges. Decent provisions available in town.

This is a bucket list item and crowning point for a daytrip up and back from Rattlesnake Lake. The 18-mile ride up to the Pass is relatively easy railroad grade and doable, even if you don't think you can get up here. But the highlight is then going through the tunnel to a completely different world on the other side. Definitely bring a jacket (it's maybe 45 degrees in there?) and absolutely deck your bike in the brightest lights you can find. The drip, drip, drip of water and murmurs of other people will follow you throughout the 2.3 mile tunnel. There is a very nice rest area in Hyak on the East side of the tunnel - lots of water, a bike repair stand and tools, and a nice spot for a picnic before you turn around and zoom down the trail in a third of the time it took to come up. Or you can continue on to the East if you want!

If you have been riding West to East, this is what you have been waiting for. A unique bridge over the Yakima River. You can cross the river, stand on one side, stand on the other, stand in the middle. The bridge doesn’t mind either way. Very high quality bridge that doesn’t move when you walk on it because it used to support trains. A great place to reflect on things that have happened and say well “that’s water under the bridge”, and you’ll be both literally and figuratively correct at the same time. Can’t beat that.

This is more of a lowlight. I'm not gonna lie... But you need to be warned. This section between Easton trailhead and the Yakima River bridge #4 just West of Cle Elum has very little going for it. It is flat; very flat. It has gravel; lots of loose gravel with two narrow hard-pack lines you need to stay within to move along. It parallels I-90, which creates a loud constant roar that battles the crunch of gravel for your hearing pleasure. Long parts of it are straight; very straight. The view is exactly the same the whole way; a hedge to the North and farmland to the South. Mostly, you are going to be looking forward to getting through this part of the trail. Think of it as purgatory, but also think of it as the price you will pay to visit the much more pleasant parts of the trail at either end.

This is the last tunnel you will see until (or the first tunnel you have seen since) Thorp. Wooded, along the lake, nice spot to stop.

Say hello to a friend. If you are travelling West to East, this is the first of many times you will cross over the Yakima River. OR... If you are travelling East to West, say goodbye to the friendly river you have been crossing over and over.
