I think this is meant to be noted as 'Yellow Trail'.
Per my GPS and starting at the lot by the park office, the trail runs appx 4.0 miles and has an elevation gain of 545ft. I counted six (6) substantial climbs in total. You cross the paved activity loop four (4) times along the way, including a brief walk early before turning at the overpass and towards the first major hill.
Got lost on two occasions:
1) Yellow Trail combines with the blue trail briefly, but markings aren't great. When they combine, turn right!
2) parking area #17, trail doglegs to the right while passing behind restrooms. Look for picnic tables to right of restrooms to continue journey.
Trail ends at picnic area #16, however, this is where the white trail comes in handy. Follow white across driveway, will lead back to paved road right at driveway to park offices. Total of combined trails should be 5.0mi.
Nice mix of trails.
If you want a good, thorough review, see David R's. It says it all. I hike here a lot, but mostly because it is close to home and easy to get to. I have probably been on every inch of every trail here, and it's neither too difficult, or too easy ( if you work it right). A big plus on hot summer days is the Creek. Nothing is better than sitting on a rock dangling your feet into the nice cool water after (or during) a long, sweaty hike! It can be quite crowded, especially on weekends, but once you get off the trails near the multi use path, you are not likely to see as many hikers.
