Surprise Lake and the surrounding land is entirely on private property. The road to the lake is gated, but kept open to hikers by the property owners. To retain access to this lovely lake, please respect the private property and refrain from entering any structures you may encounter on your outing.
The two-mile hike to Surprise Lake follows a Forest Service road for its entirety. You'll pass creeks and through forests with the occasional view of the valley before arriving at the lake.
