You won't have to venture far off the trail to find them, but you will have to use all your geosenses to sniff these out! The trail itself is easily accessible with plenty of street parking on Pacific Rim Blvd. Bring your own writing utensil and make sure to replace just as you find them. Good Luck!
Take a nice stroll down the shaded path to the creek. If you end up next to a chain link fence, you've gone too far.
