Dog Mountain Trail is considered a difficult hike, covering 6 miles roundtrip with an elevation gain of 2,800 feet. The steep uphill climb earns it a reputation as one of the most strenuous hikes in the Columbia River Gorge area. According to the Columbia River Gorge National Scenic Area, the average hiker takes 4-6 hours to complete the ascent and descent.

The trail starts off relatively flat and wide as it follows the Columbia River. However, around 2 miles in the path narrows, traverses up a ridge, and the incline sharply increases. Prepare for many switchbacks and stone steps cut into the mountainside. The upper section above the treeline is extremely steep, gaining 1,500 feet in just 1 mile.

Hikers should be prepared for a challenging cardiovascular workout. Proper footwear, hiking poles, snack/water breaks, and pacing yourself are highly recommended when tackling the uphill trek to the summit. The difficulty rating makes Dog Mountain suitable only for experienced hikers and those in good physical shape.

Trail Conditions

The trail to the summit of Dog Mountain is well-maintained but exposed in sections with some narrow and steep parts along the way. According to the US Forest Service, hikers should be prepared for drop-offs adjacent to the trail that can be risky, especially when carrying children.

Sections of the Dog Mountain trail can be muddy and slippery when wet. The steepness of the trail, combined with wet and muddy conditions, creates the potential for falls. As noted on the Washington Trails Association site, the trail to the summit has an elevation gain of 2,800 feet over 3 miles, making it a strenuous climb.

Proper footwear with good traction is highly recommended. Trekking poles can also help stabilize footing on the steep sections. Checking conditions in advance and avoiding the trail after heavy rains or snowmelt can help mitigate risks.

What to Bring

Make sure to pack the proper clothing and gear to have a safe and enjoyable hike up Dog Mountain:

  • Sturdy hiking shoes – The trail can be rocky and uneven in sections, so sturdy footwear with good ankle support and traction is essential.
  • Layers of clothing – With the variable spring weather, be prepared by dressing in layers. Bring items like a base layer, shirt, fleece jacket and rain jacket.
  • Rain gear – Even if the forecast looks clear, always pack a rain jacket and pants in case conditions change.

Dog Mountain Trail has some key hazards to be aware of before hiking. The trail gains over 2,800 feet in elevation in just 3.5 miles, so the grade is quite steep in sections according to KGW News. The steep slopes combined with loose gravel, roots, and rocks mean you need sturdy footwear with good traction and trekking poles are highly recommended.

Hikers should use caution near the edge of the trail as there are steep drop-offs and no guardrails according to the Smile4Travel guide. The trail is narrow in areas, so be prepared to yield for others passing. Sliding on muddy or gravelly slopes can be dangerous, so check conditions and only attempt the hike if properly equipped.

Summer thunderstorms are common in the Columbia River Gorge, bringing the danger of lightning strikes. If you hear thunder, turn around and get below tree line immediately. Do not seek shelter under trees or on exposed ridges. Be prepared to wait out the storm before continuing.
