(Some of) The steepest streets in Seattle

The Bicycle Alliance of Washington tweeted a link today to a city webpage listing the steepest streets in the city. No, you’re not a wuss. Cherry Street really is that steep.

This is invaluable information if you’re trying to plan bike routes, of course. And if you ride any of these streets, go ahead and give yourself a big pat on the back. You earned it!

Note: This list is from the 1960s, so some of the streets no longer exist and some street names say “Ave N” instead of “Ave E.” But you get the idea: It’s freaking steep! As you can see from the comments below, the list is not exhaustive of the steep streets. It’s Seattle. We have tons of them.

    That block of Northwest 60th has been turned into a really cool P-Patch! The sidewalk is all stairs.

    Also, I’m pretty sure that Mercer between Eastlake and Melrose doesn’t actually exist anymore!

    • Tom Fucoloro says:

      Ha! Yeah. The data is from the 60s. So the slopes will be pretty accurate, but not all the roads exist anymore, unfortunately.

      • Ben Lukoff says:

        A lot of those “Avenues North” are now “Avenues East,” too. But still a fascinating map. Also… imagine what some of these figures would have been like before regrading!

    • Chuck says:

      Used to live right by this one. It takes your breath away walking. And it has those sidewalk bumps. Would be interesting to try on a bike!

  2. Ben Lukoff says:

    Fascinating list, that is.

  3. Uwe Bergk says:

    There is one street I am missing from the list and consider very steep and probably one of the most challenging climbs in Seattle as it gets steeper and steeper as you go. The street is W Dravus street, roughly between 23rd Ave W and 27th Ave W in the Magnolia neighborhood. I wonder what the percentage is there. Anyway happy climbing on the streets of Seattle.

    • Bill says:

      ridewithgps.com is a good place to get elevation data. Its gradient calculations seem off, so divide the elevation difference by the distance (in feet; 1 mile = 5280 feet). That bit of Dravus averages 15%.

      In West Seattle, Avalon Way SW varies between 6 and 8%. Fairmount Ave SW averages 9.7%, with a kick at the top (that the online data does not resolve) that must be 20%.

    • Slaid says:

      The sign at the bottom of the hill states ‘19%’

    • Slaid says:

      The top of Dravus is 19%

  4. Peri Hartman says:

    Those are some pretty steep streets! They left out the steepest, though:
    4th N between Fulton and Newell (north slope of QA, above the Fremont bridge). It rises from 30′ to 156′ in 445′: slope 28.3%. And, that’s an average. Phew!

  5. Kevin says:

    Does anyone know the inclination of 4th Avenue North between Dexter Avenue North and Queen Anne Drive/Raye Street? It’s the steep street visible due south when crossing the Fremont Bridge. If you google map 2779 4th Avenue North and street view it, you’ll see a guy walking his bike up.

  6. merlin says:

    A first-time visitor to my house called from 24th and Mercer asking if there was a less-steep route down to my house on 25th. She was DRIVING and was afraid to drive down that slope on a clear, dry day.

  7. If the list isn't complete or out-dated, what's the point? says:

    I already know that 19th Ave. E between E. Interlaken Blvd. and Boyer Ave. E is missing from this list. There are hills on Magnolia and Queen Anne that are clearly not on this list either.

    • Tom Fucoloro says:

      Yes, you are all apt and have torn the list to shreds. Duly noted. I’ll amend the headline.

      • If the list isn't complete or out-dated, what's the point? says:

        Oh come on now. I’m just saying.

        I had another thought too. When I do any sort of Mapmyride mapping a of a ride I did it seems to know the elevation I’ve done due to the streets I’ve traced out. That website uses Google’s data as far as I can see. There must be a way to get that data for a more complete list that covers all the neighborhoods. Just saying. That is.

      • Tom Fucoloro says:

        No, I appreciate it. That wasn’t supposed to come off as sarcastic. These comments are a lot of fun, but they certainly pointed out that the list is not really of all the steepest streets in the city.

        As for GPS-based info like mapmyride, I think the elevation data comes from the GPS and not google, but I could be wrong. Anyone know for sure?

      • If the list isn't complete or out-dated, what's the point? says:

        Well, I don’t have have GPS or even a smart phone. I literally get home and map the ride manually on my desktop computer. So I think it’s kinda funny how you would mention a GPS. My thought is, somebody has that data somewhere. Just saying. And it’s obviously not our own SDOT! Ugh.

  8. A says:

    Re: related posts: Seems there needs to be some outreach to private vehicle operators regarding the green bike box in west Seattle. The majority of trips I make through that intersection see the first car in line parked dutifully on top of the bike box.

    • dave g says:

      Thats because people believe the green bike markings mean “share” the area, like the “sharrow”

      Better communication is needed. even though there are signs saying where to stop.

      • A says:

        Better communication in the form of mandatory annual retesting for driver licenses maybe.

      • Bill says:

        I moved to WA back when there were still fools who stopped at the end of freeway onramps. Given that, the mandatory driving test was an insult, compounded four years later when I learned relicensing only required a wallet test. Heck, even Indiana, Elmer Fudd’s home state, requires a written relicensing test.

      • Bill says:

        Part of the problem is the weather did not let SDOT paint the limit line. Not that most WA drivers observe them….

  9. Doug Adams says:

    A great list! One amazing steep street not included is SW Charlestown St. between 46th Ave SW and 47th Ave SW. Surely one of the steepest arterials in the city. Folks in West Seattle have for years been terrifying unsuspecting out-of-towners by driving quickly over the crest of this one!

  10. Andrew says:

    The Roy Street hill claimed my new-ish Mazda when the e-brake failed and rolled down the hill. Thankfully, it hit a tree and nothing else!

  11. A C says:

    hey, I’ve ridden up & down some of the steepest on that list. when I was a young whippersnapper I used to seek these out. rode over Queen Anne from bottom to top to bottom many times. by my house there’s a hill one can coast down at 55 mph without pedaling, and barely tucked. keep the shiny side up, as we say in a semi-related hobby. oh yeah, once had a front tire blowout doing 30 on a downhill in Issaquah, and held it up til I got stopped… lots n lots of this n that ridin stories..

  12. Tom says:

    Hey, cool article but I think titling it Steepest Blocks would be more appropriate. And, really, riding up just about any slope for one block isn’t that big a deal–on a modern road or mtn bike. However, riding up long sections of streets such as Dravus Ave W or NE 70th St from Sand Point is a whole other story…

  13. Breadbaker says:

    North 40th between Stone and Interlake.

  14. Aaron says:

    KOM on Dravus westbound is currently 2:34 by S. Fisher. From 20th to 27th.

  15. William C Bonner says:

    Was third avenue significantly flattened in the time between when this list was made and today?

    I know that walking up University from First to 4th, I’d rate the blocks in order of steepness 2nd-3rd, 1st-2nd, then 3rd-4th. The fact that only the 3rd-4th block shows in the list doesn’t make sense to me.

  16. Transit Voter says:

    On Beacon Hill, one of our steepest streets is S. Dawson St. between 17th and 20th Avenues — and it’s a signed bike route! But cyclists almost never use it because it’s unsafe to ride downhill and impossible to ride uphill. The easy slope alternate route is 3 blocks away.

    I suspect the SDOT route designers were working from a map with no topo lines. Sometimes it does pay to actually visit the locations you are planning for.

  17. Tad says:

    The Chilly Hilly should be held over there instead of over here.
