This Portland-to-Painted-Hills loop covers roughly 320 miles and 6 hours of pure drive time, best stretched over 3–4 days in summer. It’s the most geologically diverse road trip in Oregon — active volcanic craters, ancient lava fields, technicolor mudstone hills — and it avoids the Crater Lake crowds entirely.
Most Portland-area road trips default south on US-97 and stop at Crater Lake. This route takes a sharper, more rewarding angle: east over Mount Hood on US-26, south through Bend, into Newberry Volcanic National Monument (a seriously underrated caldera system), then northeast through the high desert to the Painted Hills Unit of John Day Fossil Beds National Monument (US-26 again, closing the loop). Every stop earns its place on the itinerary.
Quick Facts
- Total distance: ~320 miles (loop)
- Total drive time: ~6 hours behind the wheel
- Best season: Late June through September; Painted Hills road is accessible year-round but peak wildflower color peaks late June
- Number of stops: 5 major stops
- Starting point: Portland, OR
- Ending point: Painted Hills, OR (return to Portland via US-26 West, ~3 hrs)
Who This Route Is For
- Perfect for geology and photography enthusiasts — Newberry’s obsidian flow and the Painted Hills’ layered reds and golds are genuinely rare landscapes
- Good fit for solo drivers and couples who want a mix of outdoor hiking and a real city stop in Bend
- Manageable for most passenger vehicles, including smaller SUVs; the roads into Newberry and Painted Hills are paved but narrow in spots
- Not ideal for large RVs over 30 ft — the Painted Hills access road (off US-26 near Mitchell) has tight turns and no hookups at the trailhead lots
Stop 1: Government Camp & Mount Hood
(Depart Portland on US-26 East — 1 hr 15 min, ~55 miles)
Government Camp sits at 3,980 feet on the south flank of Mount Hood and makes a logical first break. In late June, Timberline Lodge (a National Historic Landmark) still has snow on the upper slopes, and the Palmer Snowfield is often skiable through July — worth a quick detour up Timberline Road if you’ve never seen a ski area operating in summer. For fuel, fill up in Sandy (exit US-26 at SE Revenue Ave) before the climb; gas is cheaper here than at Government Camp. Breakfast at Mt. Hood Brewing Co. in Government Camp covers the food stop efficiently before you push east.
Stop 2: Bend, OR
(Continue east on US-26 to US-97 South — 2 hrs, ~115 miles from Government Camp)
Bend is the route’s urban anchor and a smart overnight base. Downtown Bend’s Galveston Avenue corridor has legitimate restaurants; we recommend Zydeco Kitchen & Cocktails on NW Arizona Ave for dinner if you’re arriving in the evening. Top off your tank in Bend — US-97 south toward Newberry is fine for fuel, but once you head northeast toward Mitchell on OR-26, stations become sparse. Bend is also the place to grab any camping supplies or sunscreen you forgot; summer temperatures in the high desert routinely hit the low 90s°F by early July.
Stop 3: Newberry Volcanic National Monument
(US-97 South to County Road 21 — 30 min, ~25 miles from Bend)
Newberry Volcanic National Monument, managed by Deschutes National Forest, contains two summit lakes (Paulina Lake and East Lake) inside a 17-mile-wide caldera, plus the Big Obsidian Flow — a 1,300-year-old lava flow covered in jet-black volcanic glass that you can walk across on a short interpretive trail (about 1 mile, moderate). A Deschutes National Forest Recreation Pass ($5/day) is required at most trailheads here; buy it at the Lava Lands Visitor Center on US-97 before you turn off onto CR-21. The road to Paulina Lake peaks at about 6,400 feet — afternoon thunderstorms build quickly in late June, so aim to be on the rim by 11 a.m.
Stop 4: Smith Rock State Park
(Return to US-97 North, then OR-126 to Smith Rock — 45 min, ~35 miles from Newberry)
Smith Rock State Park in Terrebonne is one of the premier sport climbing destinations in the country, but you don’t need a harness to make it worthwhile. The Misery Ridge Loop (3.7 miles, strenuous) delivers views of the Crooked River canyon and the jagged rhyolite towers that defined American rock climbing in the 1980s. Day-use parking fills by 9 a.m. on summer weekends; the park recommends arriving before 8 a.m. or after 3 p.m. There is a $5 day-use fee. If you’re doing this as a multi-day trip, camping at Skull Hollow Campground (3 miles east of the park on Smith Rock Way) is a cheaper and quieter alternative to Bend hotels.

Stop 5: Painted Hills Unit, John Day Fossil Beds National Monument
(US-97 North to US-26 East — 1 hr 45 min, ~90 miles from Smith Rock)
The Painted Hills Unit of John Day Fossil Beds National Monument sits just west of the small town of Mitchell on US-26. The hills are composed of 33-million-year-old volcanic ash deposits oxidized into bands of red, gold, black, and tan — colors that shift dramatically in the hour before sunset. There are five short trails (none longer than 1.5 miles) and no entrance fee. Cell service is essentially nonexistent between Prineville and Mitchell; download offline maps before leaving Bend. Mitchell’s Tiger Town Brewing is one of the only food options in the area and serves lunch and dinner Thursday through Sunday in summer — worth timing your arrival accordingly. From Painted Hills, US-26 West runs straight back to Portland in about 3 hours.
FAQ
How long does it take to drive from Portland to Bend, Oregon?
The direct route on US-26 East to US-97 South covers about 165 miles and takes roughly 2 hours 45 minutes without stops. Adding the Government Camp detour via Timberline Road adds 20–30 minutes. Expect heavier traffic leaving Portland on Friday afternoons in summer.
Is the road into Newberry Volcanic National Monument suitable for regular cars?
Yes. County Road 21, which climbs to Paulina Lake inside the caldera, is paved for its entire 16-mile length. The grade is steep in sections (up to 8%), so vehicles with underpowered engines or those towing trailers should use a lower gear on the descent. The road is typically snow-free by mid-June.
Do you need a permit to visit the Painted Hills in summer 2026?
As of the most recent NPS guidance, the Painted Hills Unit does not require a timed-entry permit and has no entrance fee. However, parking at the main Painted Hills Overlook trailhead is limited to about 20 vehicles; overflow parking is available 0.3 miles back on the access road. Check nps.gov/joda for any updates before you go.
Is there gas between Prineville and Mitchell on US-26?
Fuel options are very limited. Prineville has several stations and is your last reliable stop before the 75-mile stretch to Mitchell. Mitchell has one small station with limited hours. Fill up completely in Prineville or, better, in Bend before heading northeast.
What are the main summer hazards on this route?
Afternoon thunderstorms are the primary hazard in July and August, especially at elevation around Newberry and on the open high desert near Mitchell. Lightning risk on exposed trails is real; plan hikes for morning. Wildfire smoke can reduce visibility and air quality in eastern Oregon from mid-July onward — check airnow.gov before departing. US-26 over Mount Hood occasionally sees brief road closures after rockfall events; ODOT’s TripCheck app is the fastest way to confirm conditions.
Can this route be done as a long weekend from Portland?
Yes. A Friday-to-Sunday itinerary is tight but workable: drive to Bend Friday, hit Newberry Saturday morning and Smith Rock Saturday afternoon, drive to Painted Hills Sunday morning for sunrise light, and return to Portland Sunday afternoon. A 3-night trip — adding a night near Mitchell — is more comfortable and lets you catch the hills at both sunrise and sunset.
