Kruse Rhododendron State Natural Reserve is located adjacent to Salt Point State Park. Edward P. Kruse donated the land to the people of California in 1933 as a living memorial to his father, a founder of San Francisco's German Bank. The land was part of a large ranch established in 1880, on which the Kruse family raised sheep and carried on logging and tanbark harvesting operations.

Today, this pristine reserve contains second-growth redwood, Douglas fir, grand firs, tanoaks, and a plethora of rhododendrons. Each May these spectacular flowers burst into bloom and color the deep green of the forest with brilliant pink blossoms.

There are five miles of hiking trails through the quiet forest with a short loop trail that leads through clusters of rhododendrons. Ferns carpet the canyons where seasonal streams abound. In addition to the rhododendrons, other understory plants include salals, pacific wax myrtle, and California Huckleberry.
