I live in Hemet.
The train was here to ship oranges out of town to Riverside. If you haven't seen Massacre canyon yet, take State st. North until it becomes Gilman springs road. just past the Scientology center, there's a very short bridge, park on the side of the road, and walk up the canyon. There's old fireplaces and a teepee (teepee is on the left side of the canyon about 1/2 mile in) It's made of bricks and rock. not hard to find if you're looking for it.
Just past Mt. San Jacinto, there's an old park right before you reach the river on the right. I'm going to MD that area soon.
I know of a place out towards Sage on Cactus Valley rd. (I think it's called cactus valley rd.) anyways, take State st. south, eventually it will turn left. Follow it until you see the stop sign. Go straight through the stop sign, and follow the road until it turns left again. On the left, you will see a very crudely made fence (last time I was out there) go through it (I could get my truck through last time I was out there) and follow the dirt road. Go back, and towards the right, and there's some old Indian grinding stones on the ground right before the HUGE ditch. Don't try to drive through that ditch, It took an F250 with four wheel drive , and winch to get me out of there. I got STUCK!! I want to MD that area too.
Also on State st. right after you turn left off of Domenigoni PKWY, look to your right. See those water towers? Above them is a tailings pile. It's easy to see. There's a mine shaft and a tunnel up there, but the tunnel doesn't go very far in. Still neat to walk up to see.
Don't try to sneak into the waterfalls off of Hwy 74 going towards Idyllwild. you'll get arrested. my friends learned that the hard way. If you don't know where they are, I'm not telling you, but you can find them on google earth
Anyways, if you're into Shooting guns, I know a place to go. Pm me if there's anything else you might be interested in. I might know. I might not.
