Day One · Saturday

The Ride Up

Two ways to ride Saturday. Both end the night in Port Austin and both keep Beachy's lunch in Caseville and dinner at The Farm. Option I keeps the whole day on the Lake Huron coast; Option II trades a slice of that coast for the USS Edson in Bay City.

I

The Lakeshore Run

The full thumb coast — no ship
🧭Open the Lakeshore Run in Google MapsRochester → Unionville → Caseville → tip & lighthouse → Port Austin → Harbor Beach → Lexington → Port Huron → homeOpen ▸

🌊 What this option is

A calm, coastal Saturday with room to breathe — a real Caseville stop, the Caseville Eagles if the mood strikes, and the Pointe aux Barques lighthouse in good afternoon light. Less saddle time, more thumb-coast. The one thing it leaves out is the Edson.

II

The Edson Run

Adds the USS Edson in Bay City
Open the Edson Run in Google MapsRochester → Bay City → Caseville → Port Austin → Harbor Beach → Lexington → Port Huron → homeOpen ▸

⚓ What adding the ship costs

The Edson is the prize, but it's a ~3-hour round-trip westward swing to Bay City plus a 1.5–2 hr self-guided destroyer tour that eats the morning. To fit it, this option gives up:
  • The leisurely Caseville afternoon — Caseville becomes just the Beachy's lunch stop.
  • The Saturday lighthouse run — Pointe aux Barques & Grindstone move to quick Sunday-morning photo stops before church.
  • Lunch runs late (~2:30) and Colwood Bar drops to an optional quick splash.

Riding above the graveyard

Beneath the Waves

Sunday's coast road runs right over one of the deadliest stretches of the Great Lakes. Here's what's offshore as you ride south — north to south.

The Tip — Pointe aux Barques

Off Port Austin / Grindstone City / Port Hope

The focal point of the Great Storm of 1913 — the "White Hurricane," still the worst maritime disaster in Great Lakes history. Eight ships and ~178 lives were lost on Lake Huron alone in four days of hurricane-force wind and 35-foot waves. The Pointe aux Barques Lighthouse & Maritime Museum tells it. Divers also find limestone caves off the Port Austin reef and old grindstones on the bottom off Grindstone City.

The Regina & the Sanilac Shores Preserve

Off Harbor Beach → Port Sanilac → Lexington (you ride directly above this)

This whole stretch is the Sanilac Shores Underwater Preserve — 163 square miles holding ~20 wrecks within recreational depth. The headliner is the Regina, a 250-ft steel freighter that went down in that same 1913 storm with all 32 hands; she lay undiscovered until 1986 and now rests upside down in about 80 feet of water. Nearby lies the Sport, a 57-ft tug (sank 1920) — the first wreck ever given a State of Michigan underwater historical marker.

Port Huron — the Memorial

South end, where you turn for home

The bodies and the famous "mystery ship" of 1913 washed ashore along this coast. A Memorial to the Victims of the Great Storm of 1913 stands in Port Huron — a fitting last stop before turning inland.

A trail of lights

The Lighthouse Trail

The whole loop is a lighthouse run — Saginaw Bay on the way up, the tip, and the Lake Huron "Sunrise Side" all the way down to Port Huron. Here's every light you could bag, in ride order. Leave the stamp circles blank for now — a proper "visited" tracker is coming in a later version.

Saginaw River Rear Range Light

Option II side-trip

Bay City — minutes from the USS Edson

An 1876 range light on the Saginaw River, restored by a local historical society with occasional open-house tours. Worth a look only if you're already doing the Edson Run.

Charity Island Lighthouse

Boat only

Big Charity Island, out in Saginaw Bay (off Caseville / Au Gres)

An 1857 light marooned on a remote bay island, reachable only by charter (a pricey, all-day affair). Spot it on the horizon from the Caseville shore and save the landing for another trip.

Map it
visited

Port Austin Reef Light

View from shore / boat

~2.5 miles off the Port Austin tip

An 1878 light rebuilt in 1937 atop an octagonal concrete caisson. The Reef Light Association runs summer boat tours; the easy play is to walk out the Port Austin breakwall at the harbor and take it in from there.

visited

Pointe aux Barques Lighthouse

Drive-up · museum

7320 Lighthouse Rd, Port Hope — already a stop in both options

The crown of the trip. First lit in 1848; its keeper Peter Shook drowned that very year, and his widow Catherine became Michigan's first female lighthouse keeper. The current 89-ft tower and keeper's house (1857) make it one of the oldest active lights in the state — roadside, with a museum and tower climbs on select dates.

visited

Harbor Beach Lighthouse

View from shore / boat tour

Harbor entrance — tours from the marina, 1 Ritchie Dr

An 1885 light guarding the world's largest man-made freshwater harbor. You're already in Harbor Beach for church Sunday morning — walk the breakwall for the view. Saturday boat tours run in season; book ahead.

Map it
visited

Port Sanilac Lighthouse

View from the road

On M-25 at the harbor, Port Sanilac

An 1886 light that's now a private residence — you can't go inside, but it's a postcard from the saddle as you ride through, right above the Sanilac Shores wrecks.

visited

Fort Gratiot Lighthouse

Drive-up · climb it

2802 Omar St, Port Huron — the grand finale

Michigan's oldest lighthouse and the first on Lake Huron. The current 82-ft tower went up in 1829 after the 1825 original toppled in a storm; a 94-step climb earns you Blue Water Bridge and Lake Huron views. Grounds are a public beach, open daily (≈10–5 in season) — the perfect last stamp before turning inland for home.

Bad Axe, Harbor Beach, and Sandusky (MI) didn't surface a Fraternal Order of Eagles — worth a local check for a mid-thumb stop. (The Ohio "Sandusky" aeries are a different town; ignore those.)
