Day One · Saturday

The Ride Up

Saturday was a real decision between two routes: Option I, the thumb coast with Eagles aeries woven in, and Option II, the I-75 swing west to ride the USS Edson destroyer in Bay City. Option I is locked. Option II is preserved below as the road not taken — the Edson has its own ride coming (see the teaser).

I

The Lakeshore Run

Locked · the chosen Saturday
🧭Open the Lakeshore Run in Google MapsRochester → Lake Orion Eagles → Mayville Eagles → Beachy's lunch → Caseville Eagles → tip & lighthouse → Port Austin → The FarmOpen ▸

🦅 What this option is

Three Eagles aeries woven into a single Saturday — Lake Orion on the way out, Mayville mid-thumb, Caseville the hat-trick right after Beachy's — then the Pointe aux Barques lighthouse in good afternoon light. Thumb coast at a calm pace; no I-75 swing, no destroyer.

II

The Edson Run

Considered · now its own ride

⚓ The road not taken

Saturday's other route — the I-75 swing west to the USS Edson destroyer in Bay City — is preserved here as the documented alternative. The decision: not on the Thumb Loop. The Edson has its own dedicated ride coming. See the Edson Ride teaser →
Open the Edson Run in Google MapsRochester → Bay City → Caseville → Port Austin → The FarmOpen ▸

⚓ What adding the ship would have cost

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 would have given up:
  • The Eagles morning — Lake Orion, Mayville, and the Caseville hat-trick all go away.
  • The Saturday lighthouse run — Pointe aux Barques & Grindstone move to quick Sunday-morning photo stops before church.
  • Lunch runs late (~2:30) and is reduced to a single Caseville stop.

Dinner at The Farm

The gem of the trip — and it's locked in. We've got bar seats reserved for 8:00 PM, and the kitchen runs until 10, so there's no rush getting there — leaves room for the lighthouse at sunset or a drink in town first.

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

Next ride · Edson

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. Slated for the Edson Ride when we mount that trip.

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.

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.

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.

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.

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.)
