This short trail is in Big Rock Park in the city of Sammamish, opened in 2016. Great for kids, the park features a zip line, a boardwalk, and several trails that are great for kids. Some of them are even ADA compliant, so they're wheelchair and stroller accessible.
The trails vary between soft-surface dirt and gravel. The obvious trails and good signage ensures you won't get lost. In addition to the cool second-growth forest of the Big Rock Trail, the rest of Big Rock Park varies from woods to meadows to wetlands. Take your time and explore it thoroughly.
To do a short mile and a quarter hike, head for the bridge directly across from the entrance to the park. Head left along the creek down to the south end of the park, where the two trails meet. Here, follow the trail west and hike along the boundary fencing, eventually reaching a sign for the Big Rock Trail. Arrive at Big Rock in just a few steps, and continue west.
Turn left at the Wetlands Trail junction and then make a right, going North on the Meadows Trail. This eventually bends right heading east, where you can continue straight down a drive and back to the park entrance. Alternatively, turn right on the north end of the Wetlands Trail and loop back to the Big Rock Trail and back out.
