For this location, park in the Cleveland Dam parking lot. You'll be able to see 'The Lions,' the mountains used as the 'Gates of Hera' in the Kobol arc from there. Cross the Cleveland Dam bridge (another site from 'The Plan') and you'll see a path on the left leading up. Walk up the path. Right about where it begins to turn, you'll see a wooden post with a small yellow sign on it. Enter the woods here (there's an obvious path).
We found screen matching in this park very difficult (though we believe we were successful with a few Kobol shots). Did you have luck matching? Please contact us and share your pics and stories.
