Tennant Lake Wildlife Area offers boat access to the Nooksack River via two ramps (one concrete, one unimproved surface) designed for small hand-launched watercraft like kayaks and canoes, though passage requires navigating under a low bridge.

The site features developed parking, restrooms, and an interpretive center, but note that the north access via Nielsen Road was temporarily closed for flood repairs (expected to reopen February 1, 2026); access from Slater Road remains open.

A Discover Pass is required for entry, and visitors should check current conditions before visiting due to seasonal flooding risks.
