Long Valley Loop Trail is a 0.8 mile lightly trafficked loop trail located near Watsonville, CA and is good for all skill levels. The trail is primarily used for hiking and is accessible year-round.
This is a lovely easy walk that we've now done twice on Winter solstice. Come in the last hour of the day for a special golden light that makes for amazing photos. Plenty of birds and a nice visitor center to warm up in with knowledgeable docents. Plenty of parking as well.
If you are with kids or grandparents, walk out to the boardwalk and bridge, explore the ruins of the Big Barn. If you'd like a longer stroll, do the whole loop. About 2 miles for the loop.
