Silver Island Lake features a concrete boat ramp with dock located within the U. S. Forest Service campground, providing protected access to this 1,238-acre lake.

The ramp is of moderate steepness and suitable for trailered boats, though boaters should navigate with caution due to scattered rock hazards throughout the lake, particularly in the northwest corner and southern basin.

The site offers overnight parking and access to three backcountry campsites via boat, with the rustic campground providing eight free campsites (no potable water available).
