Update 3/6/2018

All trails are open again, and equestrians appear to be using the trails. Nice and quiet on a Tuesday morning. Definitely prefer to park on the Gilroy side of the park and hike up Sprig Trail, then end with Merry Go Round Trail on the way back down. Old Mine Trail is worth it for the views.

This is overall a great south county loop. It is a little crowded as far as other parks in this county go: on a Tuesday afternoon I passed a dozen people or so, including the people at the Sprig Recreation Area entrance, which is around the midpoint. This park is also a big horse riding area, but due to the recent rain, it is closed to equestrian traffic, so if you're a rule breaker like me it's a good time to let your dog off leash. This means a lot of the trails are very wide unfortunately. I love the cool, shady canopy and mix of redwoods and laurels on Sprig Trail, and the beautiful, rocky chaparral of Merry-Go-Round. I would recommend taking the loop in the opposite order the title suggests, starting with the Tan Oak Trail via Meadow Trail. The Tan Oak trail will take you to a junction with the Lower Miller Trail where you can see the really cool ruins of the Miller summer place. Legend says the park is haunted by the spirit of 19th century cattle baron Henry Miller's 8-year-old daughter, who fell from her horse and broke her neck while out on a ride. Then the Loop Trail Cut-Off will get you to Merry-Go-Round, which will descend the mountain toward the Santa Clara Valley. It is a more exposed fire road, which makes it nicer to do this direction, followed by the shady, winding climb of Sprig Trail back up to the entrance booth. Tie Camp Trail, which bisects the loop, is currently closed, as is a section of the Blackhawk Trail which is noted on the map.
