Definitely for biking and only one way. There no info posted anywhere. The trailheads should all be marked bikes only. There are a dozen trails around here, all for bikes. I wouldn’t even run on them. There’s a paved road that’s mostly shaded for a nice uphill walk. Every path that goes off of it looks specifically for biking. They are not wide enough for two bikes so I’m pretty sure everyone is expected to go downhill on the dirt paths. I was there early and only saw two people on bikes come down the trail. When we got back on the paved road and went down hill we saw dozens of bikes coming up. Not sure where they came from since there were only two cars in the parking area when I got back. Zero stars for hiking, five for biking. I’m coming back another day with my bike. Great for kids.
