Palomar does have a really cool scenic look out spot on top of it, though. Next time you go up, take a right at S7/State Park Rd (it’s the road between the top of South Grade Rd and Mother’s Kitchen). It goes a few miles over a saddle, passes a park check point and then ends at intersection with Boucher lookout loop and Nate Harrison Grade Rd (that’s a really good climb, tho more for mountain bikes than roadies since it’s mostly unpaved).

The Boucher lookout loop is closed to cars, but you can ride up it (one-way loop, the uphill leg is on the right side) to Boucher fire lookout with awesome panoramic view of the surrounding area.

You might be tempted, but I would not descend down Nate Harrison Grade on a road bike (if you go down it, it comes out on Hwy 76 about 2 miles west of Valley Center Rd turn off). It’s really narrow and rough, with lots of really tight switchbacks, and the average grade is constant 8% for 10 miles or so, shallowing out the last 2 miles thru the orange groves.
