KPDX has Oregon’s longest runway at 11,000 ft, while KLMT adds a 10,302 ft towered ILS option at 4,095 ft elevation.
The brief
Oregon flying changes fast between the coast, the Willamette Valley and the high interior. KPDX (PORTLAND INTL) anchors the system with an 11,000 ft runway, tower service, ILS capability and an FBO at 31 ft elevation. At the other end of the performance spectrum, KLMT (CRATER LAKE/KLAMATH RGNL) sits at 4,095 ft with a 10,302 ft runway and 2 FBOs. The state has 102 public-use airports. Only 11 are towered, so most Oregon airport operations remain non-towered. The top list still gives IFR pilots strong options: KMFR (ROGUE VALLEY INTL/MEDFORD), KEUG (MAHLON SWEET FLD), KRDM (ROBERTS FLD), KHIO (PORTLAND-HILLSBORO), KPDT (EASTERN OREGON RGNL AT PENDLETON), KOTH (SOUTHWEST OREGON RGNL), KSLE (MCNARY FLD) and KUAO (AURORA STATE) all show tower service and ILS capability. For GA planning, look closely at elevation, runway length, weather exposure and services. KOTH is a coastal field at 17 ft with a 5,980 ft runway. KRDM is an interior field at 3,082 ft with a 7,038 ft runway. KCVO (CORVALLIS MUNI) is non-towered but ILS-equipped with a 5,900 ft runway and an FBO.
Best of Oregon
Superlatives selected from the Oregon top airports list, with the why.
KPDX (PORTLAND INTL) has Oregon’s longest runway at 11,000 ft, tower service, ILS capability and an FBO. It is the state’s obvious heavy-aircraft gateway and the most capable IFR arrival in the top list.
KLMT (CRATER LAKE/KLAMATH RGNL) sits at 4,095 ft with a 10,302 ft runway, tower service, ILS capability and 2 FBOs. It is the standout choice when southern Oregon elevation and performance planning matter.
KRDM (ROBERTS FLD) gives central Oregon pilots a towered ILS airport at 3,082 ft with a 7,038 ft runway and an FBO. It is well suited for IFR access east of the Cascades.
KHIO (PORTLAND-HILLSBORO) has tower service, ILS capability, a 6,600 ft runway and 3 FBOs. Global Aviation and Aero Air are both listed there, which makes Hillsboro a strong Portland-area services stop.
KOTH (SOUTHWEST OREGON RGNL) is a towered ILS airport at only 17 ft elevation with a 5,980 ft runway and an FBO. For the Oregon coast, that combination is valuable in marine-layer weather.
KCVO (CORVALLIS MUNI) is non-towered but has ILS capability, a 5,900 ft runway and an FBO. It is a useful Willamette Valley option for instrument practice without towered-airport complexity.
Where pilots fly
What to know
Oregon has 102 public-use airports, but only 11 are towered. That means most airport work in the state still depends on disciplined non-towered procedures. The top list includes a dense set of towered ILS airports in and near the Willamette Valley, Portland and southern Oregon. KCVO (CORVALLIS MUNI) is the useful exception: non-towered, ILS-equipped and supported by an FBO.
Terrain changes quickly. KPDX (PORTLAND INTL) is at 31 ft, KOTH (SOUTHWEST OREGON RGNL) is at 17 ft and KLMT (CRATER LAKE/KLAMATH RGNL) is at 4,095 ft. KRDM (ROBERTS FLD) adds another interior example at 3,082 ft. The highest field listed is 25U (MEMALOOSE USFS) at 6,708 ft, so performance planning can change sharply inside one state.
The Portland area offers multiple towered options. KPDX (PORTLAND INTL) has the 11,000 ft runway and ILS capability. KHIO (PORTLAND-HILLSBORO) has a 6,600 ft runway, ILS capability and 3 FBOs. KTTD (PORTLAND-TROUTDALE) has a 5,399 ft runway and an FBO. KUAO (AURORA STATE) south of Portland adds tower service, ILS capability and a 5,003 ft runway.
For instrument work, Oregon has 16 public-use airports with ILS capability. The top list includes ILS-equipped towered fields at KPDX, KLMT, KMFR, KEUG, KRDM, KHIO, KPDT, KOTH, KSLE and KUAO. KCVO adds a non-towered ILS option. That gives pilots several ways to practice procedures across coastal, valley and interior operating environments.
Anecdotes
KPDX (PORTLAND INTL) has the longest runway in Oregon at 11,000 ft. It sits at only 31 ft elevation, which gives it a very different performance profile than high-interior airports such as KLMT (CRATER LAKE/KLAMATH RGNL).
The highest public-use field in the Oregon data is 25U (MEMALOOSE USFS) at 6,708 ft elevation. That single number explains why density altitude matters even in a state with major sea-level airports.
KGCD (GRANT COUNTY RGNL/OGILVIE FLD) has 5 runways, the most listed at one Oregon field. That is unusual for a public-use airport outside the largest metro airports and worth checking in the Chart Supplement before arrival.
Service
Ranked by services count, fuel availability, hours and host airport.
Weather
Oregon weather planning depends on which side of the state you are flying. Coastal airports such as KOTH (SOUTHWEST OREGON RGNL) sit in a marine environment where low ceilings and moisture can dominate. Valley airports can support IFR routing with several ILS options, but ceilings still matter. Interior fields such as KLMT (CRATER LAKE/KLAMATH RGNL) and KRDM (ROBERTS FLD) add elevation, density altitude and winter weather considerations. Check current ceilings, winds aloft and runway conditions before committing.
Training
Oregon gives instructors a useful mix of towered, non-towered and IFR-capable fields. KHIO (PORTLAND-HILLSBORO) is the standout service base with 3 FBOs, a 6,600 ft runway and ILS capability. KCVO (CORVALLIS MUNI) is valuable for non-towered instrument work. KEUG (MAHLON SWEET FLD), KSLE (MCNARY FLD) and KUAO (AURORA STATE) add towered ILS options in the valley corridor.

FAQ
The provided data identifies KPDX (PORTLAND INTL) as Oregon’s top airport and the field with the state’s longest runway at 11,000 ft. It is towered, has ILS capability, sits at 31 ft elevation and lists 1 FBO. The data does not include operations counts, so do not treat that as a traffic-ranking claim. From a pilot-planning standpoint, KPDX is the most capable listed airport for airline-style IFR procedures, long-runway needs and Portland-area access.
KHIO (PORTLAND-HILLSBORO), KUAO (AURORA STATE), KSLE (MCNARY FLD), KEUG (MAHLON SWEET FLD) and KCVO (CORVALLIS MUNI) all make sense for training profiles shown in the data. KHIO has tower service, ILS capability, a 6,600 ft runway and 3 FBOs. KCVO is non-towered with an ILS and a 5,900 ft runway. That mix supports towered work, non-towered pattern discipline and instrument approaches across the Willamette Valley.
Yes. Oregon has meaningful elevation changes between the coast, valleys and interior. KLMT (CRATER LAKE/KLAMATH RGNL) is towered at 4,095 ft with a 10,302 ft runway. KRDM (ROBERTS FLD) sits at 3,082 ft with a 7,038 ft runway. The highest public-use field listed is 25U (MEMALOOSE USFS) at 6,708 ft. Plan density altitude, climb performance and wind exposure carefully before treating interior strips like lowland airports.
The state data lists 55 FBOs across Oregon public-use airports. Among the top airports, KHIO (PORTLAND-HILLSBORO) has 3 FBOs, KLMT (CRATER LAKE/KLAMATH RGNL) has 2 FBOs and most other top towered fields list 1 FBO. Named fuel providers in the data include Global Aviation at KHIO, Aero Air at KHIO, Gorge Winds Aviation at KTTD (PORTLAND-TROUTDALE), Corvallis Aero Service at KCVO and Sunriver Resort at S21 (Sunriver). Verify hours and fuel type before departure.
For a coastal IFR-capable destination, KOTH (SOUTHWEST OREGON RGNL) stands out with tower service, ILS capability, a 5,980 ft runway and 1 FBO. For a Willamette Valley non-towered stop, KCVO (CORVALLIS MUNI) offers an ILS, a 5,900 ft runway and an FBO. For central Oregon access, KRDM (ROBERTS FLD) gives you a towered ILS airport at 3,082 ft elevation with a 7,038 ft runway.
The big Oregon split is coastal marine influence versus inland elevation. KOTH (SOUTHWEST OREGON RGNL) is only 17 ft above sea level, so low ceilings and coastal moisture deserve attention. KLMT (CRATER LAKE/KLAMATH RGNL) and KRDM (ROBERTS FLD) are much higher, so density altitude and winter weather can drive the go or no-go. In the Willamette Valley, towered ILS airports such as KEUG (MAHLON SWEET FLD), KSLE (MCNARY FLD) and KUAO (AURORA STATE) offer useful IFR structure.
