Many sections of the Middle Fork of the Snoqualmie River are difficult to get to because the road strays from the river, the forest is a tangle of downed trees and soft soil, or there's no parking at the trailhead. Granite Flats Natural Area provides easy access to a tame section of the river across the road from the Granite Lakes trailhead.
The trail itself is no longer than 100 yards and winds through an area being replanted by King County. Stay on the trail to protect the young trees working to establish themselves. Closer to the river the trail splits upstream and down.
The upstream spur quickly reaches the cut bank. It's a few steps down to a sometimes muddy beach. Look for animal tracks in the soft sand and mud.
The downstream spur is longer and less well defined. It parallels the river with several opportunities to climb down the bank to the rocky beach. After about 50 feet, the trail fades away.
