Dog Mountain Hike — 5 Hours of Wildflowers & Things I Wish I Knew Before I Went

I have to be honest — this whole trip started because I saw a photo on Instagram.

A hillside completely covered in yellow wildflowers, the Columbia River below, Mount Hood in the background, blue sky. I immediately sent it to my partner: I want to go there this weekend. Very spontaneous. Very underprepared. (More on that later.)

That was Dog Mountain Trail, in the Columbia River Gorge National Scenic Area in Washington State, near a small town called Carson. About 55 miles from Portland along Lewis and Clark Highway (Highway 14) — roughly an hour’s drive. Easy decision. The trail is also popular enough that people make the ~4-hour drive down from Seattle just for wildflower season.

What wasn’t easy: finding out the night before that weekend permits were already sold out.

So if you’re someone like me who plans things last-minute, this post is for you. Here’s everything I wish someone had told me before we went.

Do You Need a Permit?

During peak wildflower season (in 2026, that’s April 11 – June 7 on weekends, plus Memorial Day May 25), you need a timed-entry permit through Recreation.gov. It’s $2 per vehicle, non-refundable. Rangers check on the trail, so have it on your phone or printed out.

Also — parking costs $5 per vehicle regardless of season. A Northwest Forest Pass or America the Beautiful Pass (the US national parks annual pass) covers it.

When I tried to get a permit the night before, everything was gone. But there’s a backup plan: the free shuttle bus.

One more thing I’ve heard from locals: rangers typically leave by mid-afternoon, so if you show up after 2–3pm, chances are no one’s checking permits anymore. That said, parking is still the bigger problem — by that point on a weekend, the lot may already be full anyway.

Columbia Area Transit (CAT) runs a free shuttle from the Skamania County Fairgrounds parking lot in Stevenson (📍 520 SW Rock Creek Dr. — Google Map). Getting on the bus = your free permit for the day, and they stamp a little dog paw print on your hand as proof.

The bus is called CAT. The trail is called Dog Mountain. The stamp is a dog paw. Someone definitely had fun with the naming.

⚠️ Important shuttle timing: The last shuttle to Dog Mountain departs Fairgrounds at 1:00pm. The last shuttle backdeparts Dog Mountain at 5:00pm. If you’re a beginner hiker or tend to go slow (hi, that’s us — we took 5 hours round trip), plan to catch an early shuttle. You don’t want to be rushing the descent.

Going on a weekday means no permit needed and way less parking stress — if your schedule allows it, that’s genuinely the easiest option.

The Hike Itself

A little past the 0.6-mile mark, you hit a fork. The sign says “Difficult” and “More Difficult” — which is exactly as blunt as it sounds. Most people go up via More Difficult (faster to the summit) and down via Difficult (easier on the knees), which also turns the whole thing into a loop.

We were already feeling the climb after the first section, so we took Difficult both ways. Honestly? The Difficult route up is a pretty steady, manageable grade. There’s a natural rest spot before the two routes converge — some balsamroot starts showing up here, and you get your first real view across the gorge. (Someone in our group thought we’d already reached the summit. A hiker coming back down set us straight and told us to keep going — absolutely worth it.)

Eventually you reach a spot called Puppy Dog viewpoint, where you get a proper look at wildflowers and the Columbia River. Not the most dramatic point, but a good excuse to stop and breathe.

Then the trail opens up completely. The wildflowers, the river, the mountains — it all comes at once. I stood at the main viewpoint for a while and genuinely did not want to move. Hot, exposed, no shade — and I still didn’t want to leave.

The summit itself has more space to spread out, eat, and rest. Lots of dogs up here (leashes required). If you play Pikmin Bloom, there are apparently three mushrooms to beat along the trail — just saying.

Our Mistakes (Please Learn From These)

We went in thinking it was a 2-hour trail. My partner left his water bottle in the car. We shared one bottle for almost 5 hours. This was not smart.

Bring enough water for everyone. There’s full shade on the lower section, but once you hit the viewpoint and summit, there’s zero cover. On a sunny spring day you’ll go through water faster than you think.

The other thing: trekking poles. Going up was fine without them. Coming down was a different story — calves and toes will let you know. Halfway down we found two sticks on the ground and used those, and the difference was immediately obvious. If you don’t hike that often, poles will make the descent much more manageable.

And the AllTrail trap — search “Dog Mountain Trail” and two results come up. I noticed one that said 1–2 hours and thought: perfect, easy day. My partner looked more carefully while we were already on the trail: that one is in Canada.Make sure you’re on the Washington State version before you go.

What to Pack

• 1.0L+ of water per person — non-negotiable
• Real food (energy bars, snacks, a sandwich — nearly 3,000 feet of climbing is real work)
• Trekking poles (highly recommend), especially for the descent
• Sunscreen, hat, sunglasses (no shade at the viewpoint or summit)
• Proper hiking shoes with grip

A few other things worth knowing:

• Poison oak in the lower sections — leaves in sets of three, causes a rash, don’t touch plants off the trail
• The trailhead sign warns about ticks and rattlesnakes — not common, but good to know
• In summer, biting flies will find you the moment you stop for a photo
• There’s a vault toilet about 400 feet up from the parking lot (let’s just say… you’ll know when you see it)
• Cell service is surprisingly solid for most of the hike
