The Palomar Mountain Bike Climb is the longest and second most difficult (after Nate Harrison Grade a mile away) bike climb in San Diego County. This is also the most popular climb by bike in California's cycling popular San Diego County. Some of the points and details of interest on Palomar are: (1) 18 continuous radius hairpins - this is our favorite set of hairpins in the US, (2) Mothers Kitchen restaurant at the top - get the apple pie!, and (3) the Palomar Observatory five miles past the climb finish.
Mount Palomar is a remarkably steady climb, rarely leaving the 5-8% gradient range. Testament to the continuous smooth grade is a steepest quarter mile of only 8.6%, and a steepest mile of 8.1%. Corroborating that data point is our gradient bar graph (found under "Profile Tool") that shows 82% (10.1 miles) of the climb is in the 5-10% gradient range. Only 4% of the climb is at 10% or greater (almost all of that never exceeding 10%).

Roadway: This is an impeccable roadway from top to bottom. The continuous radius hairpins are a delight to descend.
Traffic: The first 5 miles are on busy Highway 76. After turning onto South Grade Road, vehicular traffic is mild and no cause for concern. However, beware of motorcyclists on this popular windy roadway - it attracts adrenalin junkies riding race bikes wearing body armor - be particularly careful on the right hairpins as this is where you are most vulnerable to a racer hugging the inside of the curve.
Parking: Try the market or Jilberto's Taco Shop or the market, both at the start of the climb - ask permission (Map; Street View). Otherwise, on weekends park at the Municipal Water District parking lot j100 yards southeast of start (Map; Street View)
Gear: As with any climb to significantly higher altitude, be sure to check the PJAMM weather tool on this site for the weather forecast at the climb finish.
Provisions: This climb is more like Alpe d'Huez than you would think - well . . . kinda . . . There is Jilbertos Taco Shop (C grade, but an A when you are starving after you descend) at the start, and a market (map). However, you should not be hungry when you finish because you MUST eat at Mother's Kitchen at the junction just down from the finish (7/10's of a mile)- we recommend the apple pie with vanilla ice cream! See more details in the full climb summary. Map, Street View. The Palomar General Store is next to Mother's Kitchen and has some food and drinks.

My daughter went to college in and lives in San Diego, so I normally drive the hour from San Diego for a day road trip to ride Palomar Mountain. However, I have twice stayed at Harrah's Resort just a few miles from the start which is not a bad place to stay (Map). Also consider riding Nate Harrison Grade, an epic bike climb just a few miles from the start of Palomar Mountain. Of course, the San Diego area is a tourist destination and as such has no shortage of great private vacation rental options as well.
Also consider visiting the Palomar Observatory five miles north of the General Store and Mother's Kitchen (Map; Street View; Google Map + Reviews). There is also a gift shop at the Observatory (Google Map + Reviews).

I did this did this midweek and left from Harrah’s Casino. It was annoying traffic at the beginning with aggressive drivers but then mellowed out.

The road for the first 5 miles isn’t ideal, but the shoulder is usually adequate, and on the narrow parts, traffic is going a bit slower. Once you make the turn, traffic is much lighter, and it’s just a fantastic climb. Grade is extremely steady, and you’ll be amazed at how fast the elevation flies by. The burritos at the base are a wonderful reward. We descended in the rain, but the gradual grade kept it from feeling too dangerous.

Great climb. I parked at Jilberto's across the street which seemed to be fine, and the burrito I had from Jilberto's was delicious. The first 5 miles has an off and on shoulder which makes it better than I thought it was going to be. The last 7 miles are lovely, although I did encounter some racing motorcycles which are loud and annoying. Make sure to figure out where to go once you hit the top of South Grade because there is no service up there. The descent is fantastic, although there was some gravel on the road and the road can be pretty cracked. Make sure to bring plenty of water on a Summer day, as it was sweltering on the bike up.
