Overview
Tamanawas Falls is one of the most rewarding short hikes on Mount Hood's east side, and it requires almost nothing from you in return: no parking pass, no permit, no long approach. The 3.8-mile round trip follows Cold Spring Creek upstream through old-growth forest to a 100-foot waterfall that drops from a basalt lava cliff into a deep spray pool. The name comes from a Chinook word meaning "friendly spirit," and the hike lives up to it.
Because the trailhead sits at a lower elevation than most of the popular hikes on Mount Hood's west and south sides, the trail opens earlier in spring, typically by mid-May. That makes it a good option in the shoulder season when Timberline and McNeil Point are still buried in snow. By late May, the creek is running hard with snowmelt, the forest floor is green, and the falls are putting out their most impressive volume of the year.
The trail is appropriate for families with children, casual hikers, and anyone who wants a genuine payoff without a big day. Dogs are welcome on leash. The only real logistical note is the creek crossing near the falls, which can be a challenge in high water.
The Route
Trailhead to the First Creek Junction (0.5 miles)
From the Cold Spring Trailhead on Highway 35, the trail enters the forest almost immediately, following Cold Spring Creek on its south bank. The grade is gentle here, through a mix of Douglas fir, western red cedar, and bigleaf maple. The creek is audible but mostly out of sight in the first quarter mile as the trail works through the low understory.
At roughly 0.5 miles, the trail reaches a junction. Stay left (east), following the signed route for Tamanawas Falls. The right branch climbs toward Elk Meadows, a longer alpine route that's entirely different in character.
Creek Canyon Section (0.5 to 1.5 miles)
After the junction, the trail enters the Cold Spring Creek canyon proper. This is the best section of the hike. The creek drops through a series of small cascades and pools, and the old-growth forest on the canyon walls creates a sense of enclosure that feels unlike the more open terrain on Hood's west side. Douglas firs here are large, some with trunks four feet across, and the understory is thick with sword fern and oxalis.
The trail crosses a footbridge at about 0.8 miles, switching to the creek's north bank, then climbs gently through increasingly impressive forest. At about 1.3 miles, the canyon walls tighten and the creek narrows. You can hear the falls well before you see them.
Creek Crossing and Falls Approach (1.5 to 1.9 miles)
The final approach to Tamanawas Falls requires crossing Cold Spring Creek on stepping stones. This is the one variable in an otherwise uncomplicated hike. In midsummer and fall, the crossing is straightforward: the creek is low, the rocks are stable, and you can cross without getting your feet wet if you're careful.
From late May through June, peak snowmelt turns this crossing into a more serious proposition. The water can be knee-deep with a real current, and the stepping stones may be submerged. If the crossing looks risky, turn back. The falls will still be there in July. This is not the place to take chances with small children or nervous hikers.
Once across, the trail climbs briefly through a boulder field and arrives at the base of the falls.
Tamanawas Falls
The falls drop 100 feet from a lava cliff, the basalt dark and wet against the vertical rock face. The water doesn't hit the wall; it launches free from the lip and falls clear into the spray pool below. In late May and June, the volume is high enough that the spray zone extends 40 to 50 feet from the base, and you'll feel the mist long before you reach the viewing area.
A social trail continues around the right side of the falls and behind the curtain of water, giving you the perspective of standing inside the falls. It's wet, loud, and worth doing at least once. Wear a rain jacket if you care about staying dry. Footing on the rocks behind the falls is slippery, so take it slow.
The viewpoint at the base has several large boulders to sit on and eat lunch. On weekdays, particularly in spring and fall, you may have it entirely to yourself. On summer weekends, expect company, though the east-side location keeps this trail less crowded than Ramona Falls or Mirror Lake.
Permit Requirements
No permit is required for this trail. No Northwest Forest Pass, no day-use fee, no self-issue wilderness permit. The Cold Spring Trailhead is accessed directly from Highway 35 with roadside parking along the shoulder. This is increasingly rare among popular hikes in the Pacific Northwest, and one of the reasons Tamanawas Falls is worth a dedicated trip.
When to Hike
Late May through October covers the prime window. In late May and early June, the falls run at full force and the forest is lush, but the creek crossing may be difficult. July through September is the sweet spot: the crossing is easy, the trail is dry, and the old-growth forest provides shade on warm afternoons. October is excellent for fall color, particularly the bigleaf maples in the canyon, with far fewer people on the trail.
In winter, Highway 35 stays open (it's a major connector between Hood River and US-26), so the trailhead is accessible year-round. However, the trail itself accumulates snow and can be icy in winter and early spring. If you go in that window, bring microspikes.
What to Bring
For a 3.8-mile hike with modest elevation gain, you don't need much. Carry 2 liters of water per person, a snack or lunch to eat at the falls, and layers. Even on warm days, the canyon and the spray zone near the falls stay cool. A rain jacket is useful near the falls regardless of the forecast.
Trekking poles help on the stepping-stone crossing, particularly in higher water. Waterproof boots or trail runners with good drainage are both reasonable choices depending on the season. If you're hiking in May or June, assume your feet are getting wet.
Dogs should be on leash. The canyon section is narrow in places, and the creek crossing with an off-leash dog introduces unnecessary chaos.
Trailhead Access
The Cold Spring Trailhead is on Highway 35, roughly 23 miles south of Hood River and about 8 miles north of the US-26 junction at Barlow Pass. Look for the signed pullout on the west side of the highway. Parking is along the shoulder; the area holds 15 to 20 vehicles depending on how people park.
From Hood River, take Highway 35 south for approximately 23 miles. The trailhead is on the right, well-signed. From Portland, take US-26 East to the Highway 35 junction, then head north on Highway 35 for about 8 miles to the trailhead on the left. The drive from Portland takes roughly 1 hour and 30 minutes.
The nearest services are in Parkdale, about 8 miles north on Highway 35, which has a small general store and gas. Hood River, 23 miles north, has full services including grocery stores, restaurants, and gear shops. For hikers visiting the northeast side of Hood, Lost Lake Loop is about 25 miles northwest of the Tamanawas trailhead and makes a good easy add-on hike for a full Hood day: flat and lakeside in contrast to the forested creek canyon here.
