Trail Highlights

1. Rodney Falls & Pool of the Winds (0.75 miles in): This picturesque waterfall and rock chamber offer a perfect spot for a quick rest and some photos.

2. Hardy Falls (1 mile in): A second waterfall along the route, adding to the scenic beauty.

3. Summit Views (3 miles in): On a clear day, expect panoramic views of Mount Hood, Mount Adams, and the Columbia River Gorge.

Getting There…

Hamilton Mountain Trailhead is about 50 minutes from downtown Portland. There is no public transportation to the trailhead, so you’ll need a car or a ride. Use Google Maps to Hamilton Mountian Trailhead for precise navigation.

What to Bring

• The 10 Essentials (navigation, extra layers, headlamp, first-aid kit, extra food/water, etc.)

• Proper Footwear: Trail runners work, but hiking boots are recommended for traction.

• Layers: Weather can change quickly in the Gorge, so bring a windproof/rain jacket.

• Trekking Poles (optional): Helpful for stability on the steep descent.

• Plenty of Water: There are no refilling stations on the trail. A reliable guideline for many people is to carry one liter of water for every five miles of hiking. 

Trail Etiquette & Safety

• Leave No Trace: Pack out all trash, including dog waste (no leaving bags on the trail!).

• Stay on the Trail: Protect delicate ecosystems and prevent costly erosion by avoiding shortcuts and do not cut switchbacks.

• Wildlife: Expect to see birds, squirrels, and possibly deer. Give wildlife space.

• Weather Check: Conditions can change fast, so check forecasts before heading out (NOAA Forecast).

Best Time to Hike

• Spring: Wildflowers bloom, and waterfalls are at peak flow.

• Summer: Warmer weather but more crowded. Hike early for solitude.

• Fall: Crisp air and golden foliage.

• Winter: Possible snow—come prepared with microspikes if it is icy.
