Hike along one of the old railroad grades on Tiger Mountain, exploring the forests near Issaquah.

The first hundred yards of this trail are rather obscured, and the trail can be hard to see, but the grade levels out and while the footpath itself remains narrow, there is plenty to see.

Surrounded on both sides by various native plants, hikers can enjoy bleeding heart, vanilla leaf, waterleaf, fringe cup, salmon berry, tall wild grasses on this level, easy hike.

The trail parallels the TMT, with the TMT at most a few hundred feet upslope. But hikers on the Railroad Grade get a much wilder experience than on the TMT, and the western part gets very little use.

A bridge at one creek crossing has been completely washed out from the trail, but when the water level is low, there is no problem just stepping across the creek and finding the trail on the other side.

Continue on the Railroad Grade, crossing the TMT then cross Road 4000 at the Paw Print Rest Area.
