How to get there
Monomoy National Wildlife Refuge is in Chatham, Massachusetts, on southeastern Cape Cod. For mainland walking trails, use the Morris Island unit parking lot at 30 Wikis Way. The visitor center and staff offices are at 791 Main Street; opening depends on volunteer availability. North Monomoy, South Monomoy, and Minimoy require boat access, which the U.S. Fish & Wildlife Service does not provide. Contact refuge staff at (508) 945-0594 for current access guidance.
- Morris Island unit
Mainland trail access from the parking lot at 30 Wikis Way, Chatham. Trails are accessible year round, but intertidal sections may be inaccessible at high tide. This unit is outside the wilderness.
- North Monomoy Island
Offshore access is by boat only. Confirm current access and landing guidance with the refuge. The Service does not operate public boat access, and pets are prohibited.
- South Monomoy Island
Boat-only island access, with a lighthouse complex on the island. Pets are prohibited. All island access, including the lighthouse, will be restricted during the prescribed burn planned for October or November 2026.

An offshore wilderness shaped by storms
Monomoy Wilderness lies within Monomoy National Wildlife Refuge south of Chatham, at the southeastern corner of Cape Cod. Designated in 1970, the wilderness covers 3,244 acres. Its setting is a shifting coastal landscape: dunes face the Atlantic on the eastern shores, while salt marshes and mudflats occupy the western side. Severe winter storms separated Monomoy Point from the mainland in 1958; North and South Monomoy became separate islands twenty years later. That history matters when planning a visit: this is a coast shaped by erosion and storms, not a fixed network of inland trails. The broader refuge includes North Monomoy, South Monomoy, and Minimoy islands, plus the mainland Morris Island unit. Morris Island provides walking access to refuge habitat, but it is outside the designated wilderness.
Choose between mainland trails and offshore access
The main planning decision is whether to walk the mainland refuge trails or arrange an offshore visit. Morris Island trails are accessible year round from the parking lot at 30 Wikis Way in Chatham. Parts of the Morris Island Trail are intertidal and may be inaccessible at high tide, so check tides before setting out and avoid relying on an exposed section for the return. North Monomoy, South Monomoy, and Minimoy are accessible only by boat; the U.S. Fish & Wildlife Service does not operate public boat access. Confirm current landing and access guidance with refuge staff rather than treating an island shoreline as an unrestricted arrival point. The visitor center and staff offices are at 791 Main Street, separate from the trail parking, and open on a limited basis depending on volunteer availability.
Wildlife comes first
Monomoy protects feeding, resting, and nesting habitat for coastal wildlife. Migratory birds use the islands' dunes, marshes, and mudflats, with piping plovers and roseate terns among the notable species. The wider refuge also supports horseshoe crabs, tiger beetles, and gray seals; gray and harbor seals winter along the coast. Bring binoculars and watch from a distance rather than approaching animals for a closer view. Pet rules reflect the sensitivity of these habitats: pets are never allowed on North Monomoy, South Monomoy, or Minimoy. On the mainland Morris Island trails, dogs are prohibited from May 1 through September 15 to protect nesting wildlife. Leashed dogs are allowed there from September 16 through April 30. Keep the mainland and offshore rules distinct when deciding whether a visit can include a dog.
Check access before committing to a trip
Use current refuge access guidance when planning an island visit, especially if South Monomoy's lighthouse is part of the plan. A prescribed burn is planned for October or November 2026, with the actual date dependent on weather and fuel conditions. The work is expected to take one day, with active burning lasting several hours and covering up to 90 acres. All of South Monomoy Island, including the lighthouse, will have restricted access while burning is in progress. Smoke may be visible for several miles and may linger afterward. The burn is intended to reduce hazardous fuels and improve common and roseate tern habitat by reducing thick beach grass, thatch, and woody vegetation. For ordinary visits as well, check the public access map, tides, and coastal weather before leaving; mainland trail availability does not establish offshore access.

Route options
- Morris Island Trail
A mainland refuge walk starting from 30 Wikis Way, rather than an entry into the designated wilderness. Plan around tides because portions of the trail are intertidal and may be inaccessible at high water.
- North Monomoy Island boat-access visit
An offshore option for experiencing the island's coastal habitats. Arrange boat access independently and confirm where public access is currently allowed; do not assume a maintained walking route or unrestricted landing.
- South Monomoy Island boat-access visit
An offshore visit to an island with dunes, marsh habitat, and a historic lighthouse complex. Confirm landing and walking access before departure, including restrictions associated with the planned October–November 2026 prescribed burn.
Sample itineraries
- Morris Island orientation day · 1 day
Start at the Morris Island unit parking lot at 30 Wikis Way in Chatham. Walk accessible portions of the trails, planning around high tide. Look for coastal birds and learn the refuge’s layout. This mainland outing is within the refuge, not the designated wilderness.
- Offshore wilderness day · 1 day
Arrange boat transportation independently for a visit to North or South Monomoy. Confirm permitted landing areas and current access with refuge staff before departure. Focus on observing the dunes, marshes, and coastal wildlife from accessible areas. The refuge does not operate public boat access; arrange your return before setting out.
