Dog Mountain is one of the most amazing hikes in the Northwest — just don’t take it lightly

A hiker and a dog walk return from the wildflower meadows at the top of the mountain.

There are a lot (a lot!) of great wildflower hikes in the Columbia River Gorge. But the best of the best? It might just be Dog Mountain.

The 2,948-foot peak is one of the tallest on the Washington side of the gorge. From late summer through the winter, it’s yet another challenging summit with spectacular views, but come spring, when the sun-drenched meadows fill with colorful flowers, it’s a veritable wonderland.

Poison oak is common along the trail up Dog Mountain and throughout the Columbia River Gorge.

I made another trek up Dog Mountain this year, showing up on a weekday smack in the middle of wildflower season, which runs roughly from April to June. As I slowly marched up the steep, winding trail, a hiker on her way down grinned and said, “the flowers are ready for you.” All I could muster in reply was “thank god,” because at that point, only a couple miles in, my legs were already burning.

Hikers walk through a milder forested section of the trail.

While Dog Mountain is famous for its flowers, it’s infamous for the hike to see them. Every year it draws crowds of excited visitors (so many that the U.S. Forest Service had to implement a permit system in 2018 that limits access on spring weekends), some of whom inevitably show up wholly unprepared for the experience.

Dog Mountain is not an easy hike. It’s not even an intermediate hike. This is objectively a difficult trail that will challenge experienced hikers and punish anyone who tries to take it lightly.

As the spring wildflower bloom continues — the carpets of yellow balsamroot flowers covering the green slopes like a shot from “The Sound of Music” — Dog Mountain will continue to beckon. For those who heed the call, here’s what you need to know about the classic Pacific Northwest adventure.

Wildflowers everywhere

The big, bouncy balsamroot flowers might be the stars of Dog Mountain (and most of the Columbia River Gorge), but they’re far from the only flower in the area. On iNaturalist, the nonprofit, crowd-sourced nature ID website, there have been more than 150 verified wildflower identifications on Dog Mountain.

On my hike, I spotted at least two dozen wildflowers alongside the trail, which came in a rainbow of colors, most hidden among the forest of green.

There were the yellow flowers of Oregon grape (which grew just about everywhere), as well as glorious yellow wallflowers, precious buttercups and the little yellow stream violets with their little distinctive stripes.

White Hooker’s fairy bells hung delicately in the underbrush, while white death camas bloomed in brilliant clusters, and the funny Dutchman’s breeches flowers popped up whimsically here and there.

Purple flowers grew on just about every section of the trail, from the stray lupines near the trailhead to the larkspur in the summit meadows, with tiny purple pea flowers and shortspur seablush blooms hidden in the shade of the trees. The occasional small carpet of purple phlox was a welcome addition to the balsamroot bloom.

Hikers navigate the trail that cuts through the upper meadow to the summit.

In between the yellows, whites and purples were a few darling pink trilliums; the vibrant blue-eyed Marys; the fascinating brown-and-yellow spotted checker lilies; huge hanging clusters of green bigleaf maple flowers; and the stunning red paintbrush, which added yet another color to the palette atop the mountain.

While most people time their hikes to the balsamroot bloom, there’s so much more to see — you might just have to look a little closer.

Yellow balsamroot wildflowers are the star of Dog Mountain.

A truly tough hike

Dog Mountain isn’t the steepest or most challenging hike in the region, but it’s certainly up there. The roughly 6.5-mile out-and-back hike features about 2,800 feet of elevation gain, including some particularly brutal stretches.

The hike is something of a baptism by fire, starting hikers off with some seriously steep switchbacks for the first half mile. A signed junction then points you to either the “difficult” path or the “more difficult” path — a hint that whichever way you go will be tough going. (One thing to consider is that the merely “difficult” trail has better views of the Columbia Gorge, including a cute mini meadow of balsamroot flowers.)

The branching paths converge around the 2-mile mark, at which point the trail ascends yet another brutal switchback that maxes out at a 31% grade (that’s steep!). Once you conquer that section, your reward is close at hand: the trail soon opens up into the famous Dog Mountain meadows, which in mid-spring are absolutely filled with flowers.

Yellow balsamroot flowers bloom on the steep, wind-swept slopes of the upper meadow.

Puppy Dog Point lies straight ahead, where you can stop for sweeping views of the Columbia River Gorge, including a particularly nice look at Wind Mountain to the west and the edge of the Eagle Creek fire damage across the river. For many hikers, this is a fine spot to turn around — but there is more trail go.

Hikers and their dogs walk the trail up Dog Mountain in the Columbia River Gorge, as spring wildflowers bloom.

Continue uphill along the wind-exposed slope of the mountain, walking carefully among the loose rocks that fill the middle of the trail. There’s one more leg-burning climb to the top. After that switchback, stay left at an unsigned junction to reach the summit, where you’ll find a wide area to sit and rest.

Those who can’t get enough Dog Mountain can add an optional loop near the top. On your way back down from the summit, go left instead of right and follow the (sometimes overgrown) trail through the woods. In about half a mile, the path emerges at Puppy Dog Point.

However you make your way down, you can go back the way you came, or go down whichever of the “difficult” or “more difficult” paths you didn’t take on the way up. No matter which way you go, it will be a steep descent back to the trailhead.

Don’t take Dog Mountain lightly

Every time I’ve ever hiked Dog Mountain, without fail, I’ve seen a very specific kind of hiker: wearing shorts and a T-shirt, in tennis shoes, carrying nothing but a single small bottle of water. I can’t emphasize this enough — DON’T BE THAT PERSON. This is not a hike to take lightly.

First of all, there is the sheer difficulty of the trail itself, which is challenge for even the most seasoned hikers. Then there’s the many sharp drop-offs, only a step away from the narrow trail that is cut through the slopes. There are also occasional patches of slippery loose rock, not to mention hungry ticks lying in wait during the warmer months and hefty stands of poison oak that proliferate alongside the trail.

Aside from bringing the 10 essentials, you’ll want to make sure to dress in layers. While the lower portion of the trail can be balmy, temperatures can plummet by the time you reach the upper meadow, where wind whips up the side of the mountain.

You can find a restroom at the trailhead, but after that there is nowhere to find relief or water on the trail. You will only have what you are carrying.

Those who need to take extended rests will need to rely on the occasional rock or log (there are no benches on Dog Mountain). Your most common place to rest is against the side of a tree between switchbacks — something you’ll surely need to do at some point on the hike.

A note about actual dogs

People love to bring their dogs to Dog Mountain, and (most) dogs seem to enjoy the adventure, too. But pet owners should note that leashes are required on the trail. The rule is frequently flouted (on my hike, about half the dogs I saw were off leash), but it’s in place for a good reason: the wildflower meadows that have made Dog Mountain famous can be endangered by wandering pups (or rogue content creators, for that matter).
