I have ridden out there many times during the year, rain, wind, and heat, day or night. Being out there by yourself at night will test your will power or stupidity in my case

Don't kid yourself about riding in the heat. You will find that you will be the only person around so don't think someone will come by soon to help out if needed. I've started in 105 degrees at 5PM before and I'm not saying it's the smartest thing to do by yourself. After you get more than a mile away you won't see hikers for the most part. Down load trailforks app and check the trails out beforehand.
1. The goat trails- Behind Vons and park in their lot. I don't trust the folks hanging around the TH. Start by climbing up the road and go until you run outta legs and/or time, turn around and find interesting single track down. Not hard to find you way around up there. It's rocky and steep in places so top off your sealant or carry a tube. The view at night is unreal but please read the first paragraph again
2. La Quinta area/Boo Hoff trails- Probably your best bet here. Head off to the right going south/west bound. Heading straight to Boo Hoff or left to the cove to lake trail and you will find DEEP sand. Have fun pushing through that. I find the trails over on the right fun to play on and you'll be able to find your way around to Boo Hoff and up if you want. Turn around when you feel like it and take the ST braids where you want back to the car.
Once again, drink a lot of water a least two days before and drink as you ride. You won't feel like your losing fluid since it drys so quick.
If you ride out there, be prepared and have a safe time:thumbsup:
