The stones along Twelvemile Beach are horn coral from
an ancient sea, polished granite and quartz rounded like
eggs, and disk-shaped fragments of Jacobsville sandstone.
Colorful Cliffs The name Pictured Rocks comes from the
streaks of mineral stain decorating the face of the cliffs.
The streaks occur when groundwater oozes out of cracks.
The dripping water contains iron, manganese, limonite,
copper, and other minerals that leave behind a colorful
stain as the water trickles down a cliff face.
The cliffs’ ramparts are composed of 500-million-year-old
Cambrian sandstone of the Munising Formation, which
makes up much of the angled slopes and features like
Miners Castle. Closest to lake level is the Jacobsville
Formation, a late-Precambrian mottled red sandstone
that is the oldest exposed rock in the park. Covering all
is the 400-million-year-old Ordovician Au Train Formation,
a harder, limy sandstone that serves as a capstone and
protects the underlying sandstone from rapid erosion.

A Powerful Lake
Measured by surface area, Lake
Superior is the world’s largest
freshwater lake—350 miles long,
160 miles across, and over 1,300
feet at its deepest point. Drained,
it would fill a pool the size of the
lower 48 states to a depth of
nearly five feet.
Lake Superior acts like an inland
sea, creating powerful storms
and impacting the surrounding
land. Its cold water moderates
the climate, keeping summer
cooler and winter somewhat
warmer. Mist, fog, wind, ice, and
snow affect the soil, plants, wildlife, and people who live nearby.
Powered now by solar energy, the
1874 Au Sable Light Station still warns
mariners about the dangerous Au
Sable reef.

Booming Commerce
In the 1800s people made fortunes
here from timber and mining. Vast
forests of white pine, beech, and
maple fed the demand for lumber.
Blast furnaces produced pig iron
for the growing railroad industry.
Boomtowns developed along Lake
Superior’s southern shore.

Indigenous to the area harvested
furs and dug minerals from the
land. Place names like Miners
Castle and Grand Marais come
from written accounts of early
expeditions.

Native Peoples
After the glaciers retreated north,
Native people made summer camps
on the coast between what is now
Munising and Grand Marais. Little
evidence of their camps remains
today. Later, Anishinaabek people
hunted and fished here in summer
on their way to areas farther east.
Today their descendants continue
these traditions.

With each season Lake Superior
shows a different mood: summer’s
gentle waves, autumn’s furious
storms, or winter’s icy stillness.
Beaver Basin Wilderness includes nearly 12,000
acres of forests, streams, lakes, wetlands, and 13
miles of Lake Superior shoreline.
Pictured Rocks National Lakeshore consists of two
zones. The Lakeshore Zone is federal land managed
by the National Park Service (NPS). The Inland Buffer
Zone is a mixture of federal, state, and private
ownership. Respect the rights of private landowners.
Congress designates Wilderness areas to
protect forever the land’s natural conditions,
opportunities for solitude and recreation, and
scientific, educational and historical values. The
designation benefits future generations. Learn
more at www.wilderness.net.
The Wilderness within Lakeshore Zone spans
from Spray Falls and part of Twelve mile
Beach. It also includes the area of Beaver
Basin. The Inland Buffer Zone covers some
of the area inland beyond the Lakeshore
Zone and Wilderness Zone.

Plan Your Visit
Munising Falls Visitor Center is on the park’s
western end. Stop here to pay your entrance fee
and get park information. Enjoy a short walk to
Munising Falls. Open daily mid-May to midOctober. Winter hours depend on staffing.
Grand Sable Visitor Center, at the foot of Grand
Sable Dunes on the park’s eastern end, offers
information, exhibits, and a bookstore. Open
daily in summer as staffing permits.
Passes and Fees Entrance fees are required for
all visitors. Pay online via www.recreation.gov,
via QR codes on bulletin boards, or at the
Munising Falls Visitor Center.
Pets are allowed in limited areas of the park.
They are prohibited on most trails. Ask at visitor
centers or check bulletin boards or the park
website. Where pets are allowed, they must be
leashed and attended. Pet waste must be picked
up and disposed of in trash. Pets and domestic
pack animals are prohibited in the backcountry.
Viewing the Cliffs The colorful Pictured Rocks
cliffs in the western part of the park are best
viewed from the water. Concessioners offer boat
and guided kayak tours along the cliffs in sum-
mer. Some parts of the cliffs can be seen from
land. Go to Miners Castle, Miners Beach, or the
North Country Trail for the best viewing access.
Hiking and Walking Pictured Rocks offers 100
miles of trails. Get maps and information at
visitor centers or on the park website. Sections
of the North Country Trail and other trails give
you spectacular vistas of lakes, cliffs, dunes, and
waterfalls. Plan ahead and be prepared. Know
the distance, have a map, and tell someone
where you are going. Carry plenty of water and
food. Wear and bring appropriate clothing.
Come prepared for rapid changes in weather.
Beaches The sand beaches on Lake Superior
where you can sunbathe and swim are at Sand
Point, Miners Beach, Twelvemile Beach, Hurricane River, and Lake Superior Overlook. Use
caution; cold water and rough conditions can
make swimming hazardous. Be aware of boats
coming ashore. Observe surf and rip current
warnings. No lifeguards, beach camping, or
beach fires.
Sea Kayaking Use only sea kayaks (kayaks longer than 15 feet) on Lake Superior. Be prepared
for rough conditions and changing weather.
Always wear a life jacket. Have the skills to get
back in and right your boat if tipped. Carry all
necessary safety gear. See the park website for
more information. Backcountry permits are
required for camping.
Other Boating Beaver, Little Beaver, and Grand
Sable lakes are favorites for small boats, canoes,
and recreational kayaks. Launch only clean, dry
vessels to avoid introducing invasive species.
Only electric motors are allowed on Beaver and
Little Beaver lakes. Most rivers are too shallow
for canoeing or kayaking.
Drive-in Camping is available at Twelvemile
Beach, Hurricane River, and Little Beaver Lake
campgrounds. All have tables, fire rings with
grill grates, nearby potable water, and vault
toilets. No showers, hookups, or dump
stations. Find size limits and rules on the park
website. Use only downed deadwood for campfires. Campgrounds are open May 15 through
October 15. You must reserve your campsite at
www.recreation.gov or call 877-444-6777. Find
other campgrounds outside the park.
Backpacking Read the Backcountry Camping
Planner on the park webpage before getting a
required backcountry permit. The planner
includes camping sites, distances, rules, where
fires are allowed, where to find water, and how
to get permits.
Winter Activities Lots of snow means lots of
winter fun. Crosscountry ski on miles of
groomed trails. Snowmobile on a designated
park road. Enjoy ice fishing on inland lakes and
Munising Bay. Snowshoe just about anywhere.
Ice climb along the cliffs. View the winter landscape and frozen waterfalls.
Hunting and Fishing are allowed in season
under federal and state regulations. Michigan
hunting and fishing licenses are required. Trapping and target practice are prohibited. Some
areas are closed to hunting for safety reasons.
Weather and Bugs Be prepared for changing
conditions. Sudden storms develop year-round.
Hypothermia is always a threat. Bring layers of
warm clothing and waterproof gear. Black flies
and mosquitoes are common mid-May to midJuly. Stable flies are common along the shore on
warm days. Wear long, light-colored pants and
long-sleeved shirts.
Cell Service and Wi-Fi Cell phone service is nonexistent or limited in the park, but best at
Grand Marais and Munising. Find limited Wi-Fi
at Grand Sable and Munising Falls visitor centers
in summer.
Accessibility We strive to make facilities,
services, and programs accessible to all. For
more information, go to a visitor center, ask
a ranger, call, or check the park website.
Emergencies call 911
Observe These Regulations Bicycles are
prohibited on all trails. Motorized and wheeled
vehicles are prohibited in the backcountry. ORVs
are prohibited except on certain park roads;
check the park website. Federal and state laws
protect all natural and cultural features in the
park. Do not disturb shipwreck remains. Metal
detectors and remotely piloted aircraft like
drones are prohibited.
Safety First Be prepared and stay alert. Do not
climb on cliffs. Stay back from cliff edges; they
can suddenly give way. Stay on trails and boardwalks. Use the overlooks. Do not climb on rocks
near waterfalls. Sudden storms and Lake Superior’s cold water makes watersports treacherous.
Use caution when wading, swimming, fishing,
and boating. Use caution while bicycling on
park roads and H58. For firearms regulations
check the park website.
