Cruise ships anchor offshore in Thunder Bay — tenders or shuttle boats ferry you to the city boat harbor, a short walk from downtown.
💡 Pro move: Alpena is a small city — no large cruise terminal or taxi fleet. Book popular excursions (glass-bottom boat) before sailing as they sell out.
There is no dedicated cruise pier; ships anchor in Thunder Bay and tender passengers to Alpena's public boat harbor.

Alpena's shore day revolves around its extraordinary underwater heritage — but the walking trail, lighthouses, and local craft scene keep non-divers just as busy.
Board the Lady Michigan for a narrated 2.5-hour cruise over well-preserved 19th-century wrecks in Thunder Bay. Crystal-clear freshwater offers remarkable visibility — no snorkel required.
Book glass-bottom boat tours →Free admission to the national marine sanctuary headquarters. Life-size shipwreck recreations, artifacts recovered from the lake bottom, and interactive exhibits on Great Lakes maritime history.
Learn about the sanctuary →Drive or join a guided tour to Old Presque Isle Lighthouse (1840) and the taller New Presque Isle Lighthouse (1870) — both open for climbing and museum visits along a scenic Lake Huron peninsula.
Find lighthouse tours →A former limestone quarry north of town where 400-million-year-old Devonian fossils are exposed in the rock. Visitors can legally collect small specimens — a genuinely unusual shore-day experience.

Explore downtown Alpena →The Alpena Bi-Path and downtown core are the most practical walks from the tender landing, with waterfront views the whole way.
From the city boat harbor, follow the paved Alpena Bi-Path south along the Thunder Bay River to the Great Lakes Maritime Heritage Center, then loop back through the downtown arts district.
