The Sinks Trail is a 9.8 mile moderately trafficked loop trail located near Silverado, CA that features beautiful wild flowers and is good for all skill levels. The trail offers a number of activity options and is accessible year-round.
It's a real shame that his park is only open on certain day with limited time because I really wanted to get some pictures on this park on a sunrise or sunset. Limestone canyons are a bit overrated. It was really difficult to see and take pics due to the 20 person limit on a small lookout. The rangers strictly enforce this.The trail through Limestone Canyon road is really flat, lacks shade, boring and follows the road on the first half so you always hear traffic . Better using a mountain bike. Family friendly though. Most of the park is not covered in Limestone rock but was very green and there were lots of flowers. Hiked 11 miles from Augustine staging area through Sand Trap Trail, over Loma Ridge road and back down. Really long. I would recommend taking the Loma Ridge up first as this offers better views and is a better fit for more athletic hikers.
