Went to Diamond Valley Lake today - this is a close as I got! Turns out the visitor center and view point are only open Friday - Sunday.
Directions:
I 15 to Temecula
Exit Winchester and go East
To View Point - Turn right on Construction Rd.
To Visitor Center - continue east on Winchester and follow signs (about 10 miles) to The Visitor Center on other side (east side) of Lake.
