Boating and Water Access on Anderson Island, WA
Anderson Island sits in the Nisqually Reach of South Puget Sound, with real water access -- but the island's marina and launch infrastructure is smaller and more limited than its waterfront reputation might suggest. This page covers what's actually documented, and names plainly what this research could not confirm.
The Riviera's Private Marina
The Riviera community, on Anderson Island, includes a 22-slip private marina alongside its nine-hole golf course, tennis courts, and campground, per search-result summaries of the community's own materials. This research did not confirm current slip availability, membership or access requirements for non-Riviera residents, or current mooring rates -- confirm all of that directly with the Riviera community's own management before assuming access comes with any specific Anderson Island property.
Andy's Marine Park: A Beach and Trail, Not a Boat Marina
Worth stating clearly since the name causes real confusion: Andy's Marine Park, on the island's southwest corner, is an 81-acre beach-and-trail park -- a three-quarter-mile public beach, a one-mile trail from Claussen Road, and a tidal inlet functioning as a salmon nursery -- not a marina with docks and slips. It does offer water access for launching a kayak or small hand-carried craft from the beach, and limited camping by reservation for Washington Water Trails Association members specifically, but it is not a place to keep a moored boat. See the What Nobody Tells You page for more on this common point of confusion.
The Steilacoom Ferry Terminal: A Real, if Limited, Launch Point
For anyone launching a boat toward Anderson Island from the mainland side, the Steilacoom ferry terminal area includes parking and a boat ramp adjacent to the terminal building, per general search-result summaries referencing the terminal's facilities. This research did not confirm current ramp fees, parking arrangements, or whether the ramp is specifically intended for public use versus ferry-operations use only -- confirm current access directly with Pierce County or the Town of Steilacoom before planning to launch there.
Private Vessel Access to the Island
Beyond the Riviera's private marina, this research did not find detailed, sourced information on public dock or moorage options directly on Anderson Island for a visiting private boat -- covered facilities appear limited primarily to the Riviera's private marina and individual waterfront property owners' own private docks. A boater without Riviera access or a waterfront property with its own dock should confirm current public moorage options, if any exist, directly with the Anderson Island Park & Recreation District or a local marine-services provider before planning a visit by water.
The Waters Themselves: Nisqually Reach and a Real Aquatic Reserve
The waters surrounding Anderson Island are part of the Nisqually Reach -- historically defined as the stretch of Puget Sound between the island and the Nisqually River delta -- and part of the Nisqually Reach Aquatic Reserve, a Washington Department of Natural Resources-designated aquatic reserve established in 2011 covering nearshore habitat from the Nisqually Delta around Anderson and Ketron Islands to McNeil Island. That designation reflects genuine, documented ecological value -- salmon migration corridors, tideland habitat -- and it's worth knowing as a boater or paddler that these are managed, protected waters, not simply open recreational water with no ecological designation attached.
Waterfront Property With a Private Dock
For a buyer specifically prioritizing boat access, a waterfront parcel with its own existing private dock is likely the most reliable path to guaranteed moorage on Anderson Island, given the limited public and semi-private options otherwise documented. Any new private dock construction would fall under the same Washington Shoreline Management Act and Pierce County Shoreline Master Program permitting framework covered on the Seawall & Bulkhead page, and would need to be confirmed directly with Pierce County Planning and Public Works before assuming a specific project is straightforward to permit. If a specific listing already includes a private dock, confirm its current permit status and condition during due diligence, the same way an existing bulkhead's permit status should be confirmed, rather than assuming it transfers cleanly with the sale.
Ferry Transport for a Boat or Trailer
This research did not confirm whether a boat trailer can be transported on the standard Pierce County vehicle ferry alongside regular passenger vehicles, or whether trailer length or width restrictions apply -- ask Pierce County Ferry directly if you plan to bring a trailered boat to the island rather than keeping one moored there or launching it from a mainland ramp. Given that both ferry vessels are described as standard car ferries with meaningful vehicle capacity, it's plausible a standard boat trailer loads without special arrangement, but this page does not state that as confirmed.
What This Page Won't Claim
This page does not state current marina slip rates, boat-ramp fees, or specific mooring availability for Anderson Island, because none was independently confirmed this research pass. What's confirmed: real water access exists through the Riviera's private marina, Andy's Marine Park's beach for hand-carried craft, and the broader Nisqually Reach itself -- but a serious boater should confirm current specifics directly with the Riviera community, the Anderson Island Park & Recreation District, and Pierce County before assuming a particular access point or arrangement applies to a specific property.

WebFetch access to primary-source domains was blocked during this research pass, so figures are drawn from web-search result snippets rather than fully-read primary-source pages in every case. The Riviera community's 22-slip private marina is drawn from search-result summaries (Groupon, WebRezPro) describing the community's own materials. Andy's Marine Park's beach, trail, tidal inlet, and Washington Water Trails Association camping arrangement are drawn from the Anderson Island Park & Recreation District's own site, Washington Trails Association, and Sandee.com. The Steilacoom ferry terminal's parking and boat ramp are drawn from a general search-result summary referencing regional boat-launch listings. The Nisqually Reach Aquatic Reserve's 2011 designation and boundaries are drawn from Washington DNR's own site, referenced via search snippet. Facts not independently confirmed and not invented here include: current Riviera marina slip rates or membership/access requirements for non-residents; current Steilacoom terminal boat-ramp fees or public-use policy; and current public moorage options, if any, directly on Anderson Island beyond the Riviera's private marina. Confirm all current access, fees, and availability directly with the Riviera community, the Anderson Island Park & Recreation District, and Pierce County before planning boating access.
