This free Rhode Island park hides 100-foot cliffs and spray-painted war bunkers

It’s free, wild, and worth every mile

Fort Wetherill State Park sits on the eastern tip of Conanicut Island in Jamestown, Rhode Island, and it doesn’t look like any state park you’ve been to before.

You get granite cliffs dropping 100 feet to the bay, concrete bunkers spray-painted floor to ceiling, and two sheltered coves that draw divers from across New England. The whole thing is free and open year-round.

But the real draw isn’t any one feature. It’s how all of it sits together in 61.5 acres of coastline you won’t forget.

From cannon batteries to a state park on the bay

This stretch of Narragansett Bay has had someone watching it since the American Revolution.

A permanent fort went up here in the late 1800s as part of a national coastal defense network, and the site served as a battery and training camp through both World Wars.

It took the name of Captain Alexander Wetherill, a Jamestown native killed at the Battle of San Juan Hill. The military pulled out in 1946, and Rhode Island converted the land into a state park in 1972.

A hundred-foot wall of granite above the water

The cliffs are the first thing that grabs you. Smooth granite drops straight to the bay, and from the top, you’re looking across Newport Harbor and the East Passage with nothing blocking the view.

Boats move in and out below you. At sunrise and sunset, the rock turns rust and gold.

Wide ledges give you room to sit down, spread out, and watch the water for as long as you want. This is the kind of shoreline that keeps you there longer than you planned.

Walk through the tunnels of an early-1900s gun battery

The old bunkers are still standing, and most of them are open.

You can walk through thick concrete tunnels and gun emplacements that date to the early 1900s, when this fort guarded the entrance to the bay.

The walls are heavy and low, the openings face the water, and the whole setup gives you a clear picture of how coastal defense worked before modern warfare made it obsolete.

Standing inside one of those emplacements with the ocean wind coming through the gun port is its own kind of history lesson.

Spray-painted walls that change every time you visit

Those same bunkers are now covered in graffiti, and not the scrawled kind.

Full murals run across the concrete in layers of color, one piece painted over another as new work appears throughout the year.

The gray walls have turned into something closer to an outdoor gallery, and no two visits look the same because the art keeps shifting.

Set against the green cliffs and the blue water just beyond, the contrast between the military ruins and the spray-painted walls is worth a long look.

Shore diving doesn’t get much easier than this

Fort Wetherill ranks as one of the most popular shore-dive sites in New England, and local dive classes bring beginners here for their first open-water dives for good reason.

Two protected coves keep you out of open-water boat traffic, and an old boat ramp gives you a clean, gradual entry into the water.

Night dives happen here regularly because the coves stay calm and the conditions stay manageable. If you dive, this spot belongs on your list.

Two coves, two very different dives

The right cove is where beginners start. You walk down the boat ramp into shallower water, with a gentler drop and a straightforward layout.

The left cove takes a steeper path to reach, drops to deeper depths, and runs stronger currents that experienced divers come specifically for.

Both sides shelter enough marine life to make the dive worth it, and a short walk along the shoreline connects them. Pick your cove based on your skill level and go from there.

Lobsters, flounder, and tropical fish in the same bay

Once you’re under, the coves hold more than you’d expect. Lobsters and crabs work the rocky bottom.

Flounder, skate, and squid move through the eel grass beds.

Every fall, warm Gulf Stream currents push tropical fish into the shallows for a few weeks, mixing cold-water and warm-water species in the same dive.

After dark, the coves come alive in a different way, with creatures out in the open that stay hidden during the day. Night diving here rewards the effort.

Launch a kayak right from the park

A steep public ramp at the park gives you bay access for kayaks, canoes, and paddleboards.

A small beach area keeps the launch simple, and the sheltered coves give beginners a place to get comfortable before heading out.

The park sits right at the mouth of Narragansett Bay, so once you clear the coves, open water opens up in every direction. If you want a longer paddle or want to sail, the bay is right there.

Stay close to shore or go wide, depending on what you’re after.

Cast for striped bass from the rocky shoreline

Anglers find good spots all along the cliff-side and shoreline perches, casting for striped bass and tautog from rocks set directly above the water.

The mix of rocky bottom and open bay water draws a solid range of fish, and you can also head out onto the bay by boat from the ramp. There’s nothing complicated about it.

You pick a perch, drop a line, and spend a morning listening to the water below you. Quiet and productive tend to go together here.

Watch for seals and falcons from the cliff edge

Harbor seals show up in the water around the rocky points, and if you watch long enough from a high vantage, you’ll sometimes spot one.

Peregrine falcons and cormorants work the cliffs, and the coastal terrain pulls in migratory birds through the seasons, so what you see depends on when you come.

Birdwatchers and wildlife photographers set up along the cliff tops with good reason.

The height gives you sightlines in every direction, and the movement along this stretch of coast keeps things interesting.

Pack a lunch and claim a spot above the water

Picnic tables and grills sit scattered through the park, and you can pick a spot with a water view or pull back into a quieter clearing in the trees.

Wide lawns give groups and families room to spread out without crowding each other.

After a morning of hiking the cliff trails, exploring the bunkers, or diving the coves, sitting down with food and a long view of the bay is a natural finish to the day. The park handles it well and doesn’t rush you out.

Visit Fort Wetherill State Park in Jamestown, Rhode Island

Fort Wetherill State Park sits about five minutes from downtown Jamestown on Conanicut Island. Admission is free, and the park stays open year-round as a day-use area with no camping.

You’ll find parking, picnic tables, seasonal restrooms, and a steep boat ramp suited mainly to kayaks and other light boats.

If you plan to dive, bring a buddy and a dive flag, and arrange your air fills and gear before you arrive since there are no dive shops on site.

Watch for fencing around certain bunker areas and stay on marked paths near the cliff edges.
