Confirmed from Horne Trail's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.
What runners say about Horne Trail
“It follows a creek for a bit over a mile before turning uphill with fairly steep switchbacks that lead to a beautiful overlook.”
Parking is limited. This trail is great. I like that it has multiple trails branching off from it to explore. As well there is a fairly flate trail. Giving you the option to go on a nice hike or if you feel you want more of a challenge you can do that too. Per the posted signs no bicycles are allowed.
About 15 minutes in, the main trail appears to split to two branches. We took the left one that led to a series of rock climbing along and within the creek (it was dry). It sure would have been exciting for someone who's looking for challenges, but that someone was not us.
Not busy. Water in the creek and ferns galore. Dogs had a great time playing in the water. Here's one pooped pup! There is no signage at the trailhead. It is on Valleystone, not Blackstone like the maps pin said. Here is the start of the trail
A nice trail that follows a creek up a canyon. I visited in late summer, which at the time has no flowing water, but I revisted in February and there was a slight trickle of water. Maybe after a larger storm there is a more flowing waterfall. However, this trail is still awesome.
Trail conditions & character
“In the winter, after it rains, you might get your feet wet as the trail crosses the steam multiple times, but you'll be rewarded with small waterfalls all along your trek.”
“It follows a creek for a bit over a mile before turning uphill with fairly steep switchbacks that lead to a beautiful overlook.”
