Nisqually Flats is a broad, shallow estuarine area forming part of the Nisqually Delta at the southern end of Puget Sound in Washington. It is characterized by expansive tidal flats and protected waterways, offering a paddling environment distinct from the more exposed open saltwater. The primary public boat launch for accessing the flats is the Washington Department of Fish and Wildlife (WDFW) ramp at Luhr Beach, which requires a WDFW Vehicle Use Permit for parking. This launch point experiences a significant tidal exchange, with a range that can be as much as 14 feet. Paddlers must plan carefully, as it may be impossible to return to the Luhr Beach ramp at an extreme low tide. The area is part of the Nisqually National Wildlife Refuge, and a boat speed restriction of 5 mph is in effect in all Refuge waters. The channels of McAllister Creek and the Nisqually River, which feed into the delta, are peaceful, protected, and excellent for dinghies, kayaks, and canoes. These waterways allow for travel well beyond Interstate 5 to the south. The flats themselves are exposed, and paddlers should beware of hazardous tides, shallow waters, wind, and weather conditions. A notable hazard is the potential to become stranded on sandbars, as evidenced by rescue incidents. The area features an active oyster farm southwest of the main anchorage, and boat traffic is frequently present there. A common day trip route involves launching from Luhr Beach and paddling northwest across the Nisqually Flats to Anderson Island, specifically to Carlson Bay and Andrew Anderson Marine Park, a distance of approximately 10.6 nautical miles. The wreck of the WWII-era wooden tug Tsar lies off the tiny Beachcrest marina and is accessible only on higher tides. Wildlife is abundant, with many seals and a great variety of birds due to the area's status as a bird sanctuary. Historical remnants, including bits of old dikes and buildings, can be seen along the shore.
