Palomar mountain dirt road questions

Been up to Palomar observatory a few times but never on dirt. I'm planning a big bike ride from AZ to San Diego and was looking at doing dirt roads up to the observatory and back down the other side. For those of you in SoCal who might be familiar with these particular roads can you tell me if they are BBF (big bike friendly) for novice riders which might attend?

Here's the specific part of the route I'm talking about:

From east to west on map above:

1. (From CA79) - Up the mountain Oak Grove Rd/Truck Trail to
2. High Point Rd/Truck Trail to
3. Palomar Divide Rd/Truck Trail to the observatory, then
4. Down the mountain Palomar Divide Rd/Truck Trail to
5.多恩谷路
6. Nate Harrison Rd to Hwy 76

Thanks

我做过卡车路线和sta的帕鸿沟yed on it heading north and ending up in Temecula area. It is a two track jeep trail. The part I have been on would be easy on a dual sport. I can not advise you on the Doane Valley part of the road. But I am sure it is similar as these roads are used as firebreaks and access for emergency vehicles in case of fire, etc.

I did the last part of your leg this summer but from west to east. From the 76 up the Nate Harrison grade road to the top of Palomar Mountain is definitely big bike friendly. The top is around 5500 feet above sea level so check the weather if you're going in the winter.

All truck trails and dirt in that area are closed multiple locked gates.

Are those closures seasonal?

The gate connecting Palomar TT to the observatory has been closed when I've been up there.

Asked our local group for ya. If you need anything in SD, let me know.

I was just on those trails. Big bike friendly. Two problems I see. The bottom of Oak grove was locked, or I could not find the access. I need to take it from the top and see where it dumps out at the bottom. Palomar TT is closed so you will not get to the observatory therefore you cannot drop down the other side to NateHarrison. You need to back track down the Palamor Divide/ TT.

This is my back yard. With that said, I haven't ridden it for a few months so I don't know for sure what gates are open/closed. However, most of the time the gates are open, with the exception of a gate at the top of Palomar Divide that prevents you from making it all the way to the observatory from the north side of the mountain. This is because of a piece of private property that the owner has decided to close off access to the public to. You can ride almost to the top (you can get to a fire look out tower, which is cool) from either Palomar Divide trail or High Point truck trail but you'll have to go back down the highway 79 from either of those. You can make a loop out of by going up one and down the other, which is worth it and big bike friendly. The ONLY way to get to the observatory on dirt is via Nate Harrison. So you'll have to take 79 around the east side of Palomar Mnt., to westbound 76. Let me know if you have any more questions. Feel free to PM

Oak Grove Rd has been blocked off at the bottom by a private landowner. There is (was) a public easement, however the landowner sued the Forest Service and now only USFS vehicles can go through. You can see the gate here:

Nate Harrison Grade is mostly paved now !

Thanks for all the help guys!

Old Thread, but useful for me in figuring out where to start in the SD area, THANKS!
