The Grand Portage Marina and boat launch ramp are owned and operated by the Grand Portage Band of the Chippewa. The 30 slip marina receives some protection from its location within Grand Portage Bay; but the bay itself is shallow in spots and may impede deeper draft boats. The Band also operates Voyager Marina on the northwest corner of the bay.
145.9 miles northeast of the Duluth Harbor Entry, 16.2 miles northeast of Horseshoe Bay, 23 miles southwest of Isle Royale, and 43 miles southwest of Thunder Bay, Ontario.
