Isle Royale Summer 2017 Boating Guide

The regulations of Isle Royale National Park are intended to protect park resources and appropriate visitor experiences. Visitors are responsible for adhering to park regulations. The park boundary extends 4-1/2 miles into Lake Superior from Isle Royale and the outer islands, or to the international boundary. No pets are allowed within park boundaries.

Fees, Camping & Docks, Restricted Activities, Acquatic Invasives, Generators, Fishing, Firewood, Ferry Schedules


Camping permits are required for all overnight stays, including anchoring out. Permits may be obtained at Houghton, Rock Harbor, or Windigo Visitor Centers. For your convenience, contact the park prior to your visit to obtain your permit. Visibly display the permit when at dock or anchorage. When staying ashore, display your permit on tent or shelter door.

Park Fees

Visitors to Isle Royale, including those fishing in park waters, are required to pay a $7 per person daily entrance fee. This fee is charged to enter or remain within the park per calendar day. Children 15 and under are exempt. The Isle Royale Season Pass costs $60 and includes up to 3 adults traveling with the pass holder. All Federal Recreation Passes will be honored for the pass holder and up to 3 adults traveling with the pass holder. You must present your pass upon arrival in the park.

Camping and Docks

All dock space and small party campsites (including shelters) are available on a first-come, first-served basis. They may not be reserved or held for others. From late-July to the end of August, expect to find crowded conditions at docks and campgrounds. Boaters already set up at a campsite or shelter and who have a valid camping permit must be given priority access to space at the dock (when not in camp, many boaters leave fenders attached to the dock to indicate occupancy of a campsite.) Observe consecutive night stay limits for each campground, in effect from June 1 through Labor Day. You may only use one shelter and shelters may not be used solely for cooking or gear storage. Do not use staples or nails on shelters. A tent may be erected inside, but not outside a shelter. Do not change the landscape by digging, trenching, etc.

Generally, only docks that adjoin campgrounds are open for overnight use. The Rock Harbor Marina provides nightly slip rentals with utility service hook-ups.

The following docks are open for day use only from 6am until 10pm eastern time:
Mott Island Docks Raspbery Island Dock
Any NPS or concession fuel dispensing dock Passage Island Dock
Edisen Fishery Dock Amygdaloid Island Dock
Hidden Lake Dock Crystal Cove Dock
Shipwreck Mooring Buoys (for active diving only) Wright Island Dock
Any other dock posted or signed as closed to overnight use.

The following docks are closed to public use:

Malone Bay Dock (north side) America Dock
Any other dock posted or signed as closed to puiblic entry.

Spiny Water Fleas are found in Lake Superior. Please help prevent further spread of this invasive species, especially into non-infested waters like Isle Royale's inland lakes.


Aquatic Invasice Species

Aquatic Invasive Species (AIS) pose a serious threat to native fish and other species. Spiny water fleas and low levels of sea lamprey and zebra mussels are found in Isle Royale waters. All vessels (including non-motorized craft), visiting or transiting within the bounds of Isle Royale National Park, along with associated equipment, must be decontaminated by an approved method prior to entering the waters of the park. See the park newspaper for details on decontamination methods. For large non-trailered vessels, the owner shall inspect vessel hull, outdrives, trim tabs, and motors for AIS

Restricted Activities

Water skiing and personal watercraft (including vessels referred to as jet skis, waverunners, sea-doos, wet bikes, or surf jets) are prohibited. Inland lakes and streams can only be explored by paddling. Vessels with motors (even if not in use) are prohibited on inland lakes and streams.

The operation of electronic and motorized devices such as stereos, televisions, radios tuned to commercial stations, and portable generators is not permitted except in developed and open water motorized zones. Developed areas include Windigo, Rock Harbor and Mott Island. Open water motorized zones include Lake Superior waters outside of designated Quiet/No-Wake Zones.

On-board Generators

The operation or use of permanently installed (by manufacturer) on-board vessel generators is allowed from 6:00 a.m. to 10:00 p.m. EDT in developed zones, and at the following docks: Beaver Island, Belle Isle, Caribou Island, Grace Island, Hay Bay, Malone Bay, Rock Harbor, Tobin Harbor and Windigo.

The operation or use of permanently installed on-board vessel generators is prohibited at the following public docks: Birch Island, Chippewa Harbor, Daisy Farm, Duncan Bay, Duncan Narrows, McCargoe Cove, Merritt Lane, Moskey Basin, Siskiwit Bay, Three Mile, Todd Harbor, and Tookers Island.

The operation or use of permanently installed on-board vessel generators is permitted between 6:00 am and 10:00 pm EDT by vessels at anchor within Quiet/No Wake Zones except when anchored within 1/4 mile of designated park docks (listed above) where on-board generator use is prohibited.

Quiet/No Wake Zones

These zones protect the natural quiet and wilderness values sought by most Isle Royale visitors and reduce wake impacts on park resources and paddlers. Within Quiet/No-Wake Zones, vessels must not exceed 5 mph OR create a wake in excess of surrounding seas. Quiet/No-Wake Zones are not marked by buoys. Boaters are responsible for knowing the locations of Quiet/No Wake Zones.

A Michigan Fishing license is required for fishing in Lake Superior.



A Michigan Fishing license is required for fishing in Lake Superior, including narrow bays and harbors, and when transporting fish from the island to the mainland. Licenses are not required to fish the inland waters. Michigan size, season, and possession limits generally apply. See park newspaper for exceptions.

All fish in your possession count toward your limit, regardless of where and when you caught them. All fish in your possession must be measurable and identifiable by species.

Only barbless hooks and artificial lures may be used in inland lakes, streams and creeks. The possession or use of fish or fish parts as bait for fishing within the Lake Superior waters of the park is limited to fish and/or fish parts that are caught within the park. Transporting fish or fish parts for use as bait to the park is prohibited.

Disposal of Fish Remains

Lake Superior Campgrounds: In Rock Harbor and Windigo use the fish cleaning station. At campgrounds and docks, clean fish away from the dock and campsites. Do not throw pieces to gulls or into the water near shore. Scrub up and rinse away all blood and slime from any onshore surfaces. Boat out and dump chopped remains in 50 feet or deeper water.


Fires are allowed only in provided metal rings and grates. Very few campgrounds allow fires. Dead wood on the ground may be collected for use as fuel for campfires. Do not bring wood from mainland as it may harbor disease or insect pests.
Take your trash with you, do not burn it.
