Meet Michigan’s 100th State Park: Rockport State Recreation Area

Michigan welcomed its 100th state park into the fold in 2012 with the addition of Rockport State Recreation Area, located just north of Alpena.

It’s off the beaten path. The beaches on the Lake Huron side of the state are rockier than on the Lake Michigan side, so many people dismiss travel to NE Michigan. But wow, are they missing out on something so unique.

When you skip the Alpena area, this is what you’re missing.

Unique Outdoor Adventures Happen Here

Rockport State Park Recreation area is not your typical Michigan State Park.

Yes, it is expected that a campground with cabins down on the beach will eventually be built here. There already are a couple of backcountry campsites on the property.

And yes, there is a boat launch – the walleye, lake trout, and salmon fishing here is great.

The trails are abundant, with miles for hikers to explore. Mountain bikers and horses are welcome on the trails, too. These are typical state park type things.

But, Rockport State Park is also home to:

  • a gigantic, historic limestone quarry where you can dig fossils
  • a massive limestone rockpile you can climb
  • large sinkholes in the backcountry
  • several historic shipwrecks for snorkelers, divers and kayakers to explore
  • a grove of virgin pine trees
  • an old ghost town
  • a Dark Sky Preserve
  • rare sandy Lake Huron beaches
  • a Bat Hibernaculum, home to several endangered bat species

Rockport State Park Recreation Area

Located on Lake Huron, this former rock quarry was once booming with mining and shipping activity.

From 1914-1948, limestone was dug and shipped out of the deep water harbor for use in the construction industry.

Some of the materials quarried here were even used to build the Mackinac Bridge.

Today, this property is being reclaimed for a multitude of recreational opportunities.

What Can You Do at Rockport State Park Recreation Area?

1) Dig for fossils in the Quarry

This Michigan State Park doesn’t have many signs up yet. (Porcupines keep eating the trail markers!)

If you drive into the park and didn’t know about the quarry or rock hunting, you’d have no idea it was here.

Take a good look at a map before you arrive, or save one to your phone (cell service is spotty at best here.)

The Alpena area is the best part of Michigan for fossil hunting.

Ages ago, this area wasn’t walkable. It was covered by warm saltwater filled with fish and coral. (This was 350+ million years ago in a time period now called the Devonian Era, or the “age of fish.”)

The remnants of these old fish and coral are trapped here, fossilized, in the limestone in the quarry, ready for you to dig, discover, and make your own. You are allowed to take home up to 25 pounds of fossils/rocks per person per year.

(Just an FYI – snakes also love hanging out in the quarry.)

Angela Hollinshead, a mom from Greenville, MI, recently visited Rockport State Recreation Area with her son, sister, and 6&8-year-old niece and nephew. She reports:

Make sure to wear sturdy shoes, the rocks are uneven and sharp. It’s a short walk down an old road into the quarry, it took us under 10 minutes to walk there.

I took my 11-month old in his stroller, the road is bumpy but the stroller did just fine.  Once into the quarry I parked the stroller along the road and put him in my backpack carrier to explore.

There are huge boulders – I brought a rock hammer and we had fun chipping out embedded fossils.

Right away you see hundreds of fossil corals, horn coral, Petoskey stones, and brachiopods.

There is water that runs through the quarry. The older kids had a lot of fun playing in the shallow streams and shallow ponds as well as chipping away at the rocks.

If you’re new to fossil hunting, you might want to stop at the nearby Bessemer Museum for Northeast Michigan first.

Bessemer Museum for Northeast Michigan
491 Johnson Street Alpena, MI 49707

This museum is open to the public and is on a mission to teach people about the Alpena area’s geology and fossils with their exhibits and two fossil parks. You’re encouraged to bring a small trowel for prying, a water bottle to loosen fossil specimens, and a tote to carry home your fossil finds.

2) Climb the Giant Rock Pile

When mining operations at the Rockport location abruptly ended, a huge pile of limestone ready for shipment was left along the side of Lake Huron.

Today, you can climb up these tailing piles. The rocks are sharp and jagged, so be sure to wear sturdy footwear.

3) Walk the Old Pier – And Maybe Swim from It

The pier is eroding in the middle. Adventurous souls can still make it to the end, but the days for the little land bridge are numbered.

Some people choose to swim here. If you do jump in, know the water is very deep.

4) Mountain Bike, Hike or Ride a Horse out to the Sinkholes

Hiking out to the sinkholes is a big undertaking. Take water and bug spray and be prepared to be out for hours.

Plan on a 6+ mile loop over rugged terrain out to the crystal clear waters of the sinkholes.

5) Stargaze at this Dark Sky Park

Staying up late gets a thumbs up here. Miles away from major light sources, this park is one place where it feels like you could reach up and pick the stars right out of the sky.

Choose a clear evening to stay up late, download a stargazing app, and just try to stay awake to see the stars, meteors, planets, and other night sky wonders.

6) Learn about the Endangered Bats Living in the Bat Hibernaculum

There are 4 species of endangered bats that call Rockport State Recreation Area home in manmade tunnels beneath the giant rock pile in what people love to call the Bat Cave.

There is a secured grate for the bats to enter and exit the bat cave. It’s located by the large rock pile.

The grate of the bat cave (Bat Hibernaculum) is locked to prevent people from entering and disturbing them.

7) Have a Picnic

There is a small park at the base of the pier, near the entrance to the rock pile. Several picnic tables are available.

The following options are located at the north end of Rockport Recreation Area in the Besser Natural Area.

8) Visit the old Grove of Giant Virgin Pine Trees.

Many of the trees in Michigan were cut down during the 1800’s logging boom.

Somehow, a grove of old-growth white and red pines escaped the chopping block and can still be seen today. Just follow the 1.3-mile loop at Besser Natural Area and you’ll pass right by them. Also on this trail is the old Village of Bell.

9) Explore the former Village of Bell, an Old Ghost Town

You’ll see the remains of historic buildings, including a really cool old chimney, a cemetery, and safe.

Over 100 people used to live in the town back in the late 1800’s.

10) Swim at a Sandy Lake Huron Beach 

It’s rare to find a sandy beach along Lake Huron. If you visit Besser Natural Area, you’ll be in luck.

Find the secluded sandy beach that swimmers enjoy. Rockport also has miles of more remote sandy beach – but you’ll have to hike or bike to access it.

11) Kayak, Dive or Snorkel to Explore Historic Shipwrecks 

Pick your pleasure, there are multiple ways to get a good look at the shipwrecks in Lake Huron by Rockport State Recreation Area.

The Portland shipwreck off of Besser Natural Area (just north of Rockport) is in very shallow water and is easy to see from a kayak or while snorkeling.

The water in the state park is crystal clear, making it easy to see what lies below the surface.

  1. One correction: the museum isn’t “Bessemer”, it’s “BESSER”!
    Bessemer is in the Upper Peninsula. The Besser Museum is named after Jessie Besser.
