Great trail as long as you can do sustained long hills. There are a couple 1-1/2 to 2 miles long. The only part of the trail that is flat is the actual loop. That's the reason i rated it as difficult. I don't want anyone going out of their comfort zone or ability level. Big upside for most is 99% of this trail is shaded. This part of the trail has hardly any redwoods where the northern part has many more redwoods. The creek itself is beautiful but you only see it when you cross and no bridges so prepare to get your feet wet... Overall Mill Creek Horse Trail is prettier because of the redwoods. Most of the trail itself is old roads which are no longer used but are still beautiful.
