Welch Island: Lake Winnipesaukee's Timeless Boat-Only Retreat

Welch Island: Lake Winnipesaukee's Timeless Boat-Only Retreat

There are 274 islands on Lake Winnipesaukee, but few carry the layered history, quiet mystique, and pure island-living atmosphere of Welch Island. Tucked in the town of Gilford along the southern reaches of the lake — where the open water of The Broads begins — Welch Island is the kind of place that rewards curiosity. No cars, no paved roads, no bridge to the mainland. Just deep-water views, mountain silhouettes, aging docks, vintage cottages, and the unhurried rhythm of life that can only exist on a boat-access island.

Whether you're dreaming of owning a piece of island history or simply want to understand what makes this corner of Winnipesaukee so compelling, here's everything you need to know about Welch Island.

A Place Bigger Than It Looks on a Map

Welch Island is commonly cited as about 187 to 210 acres, depending on the source — making it the largest of the Gilford islands and generally ranked as the sixth-largest island on all of Lake Winnipesaukee, after Long, Bear, Cow, Governors, and Rattlesnake Islands. Its north side faces a cluster of smaller islands sometimes called "The Forties" — including Round, Pop, Fish, LeRoy, Crescent, Saints Rest, Kinneho, and Breezy Islands — while its southern exposure opens into the wide, windswept expanse of The Broads.

The views here are genuinely dramatic. From the north shore, you look toward the Sandwich Range and the White Mountains, with glimpses of Mount Washington on clear days. Sunsets paint the west and northwest shores gold every evening in summer. It's the kind of scenery that explains why people have been coming back to this island for more than a century.

Before the Cottages: Sheep, Stone Walls, and Cornfields

Welch Island wasn't always summer-cottage country. Local history — summarized in Mary G. D. Donsker's 102-page illustrated monograph "The Story of Welch Island Through 1945," published in 1984 and held at both the New Hampshire Historical Society and Gilford Public Library — traces ownership back to the late 1700s, when the island was reportedly claimed by Jonathan Moulton and Abraham Welch.

By the early 1800s, the island had passed through several hands and was being used for something decidedly unglamorous: sheep pasture. According to local history, sheep were brought to the island by barge each spring, corn was reportedly grown on-island to feed them through the season, and every winter — once the lake froze solid — the sheep were led back to the mainland across the ice. Stone walls and remnants of those old cleared fields can reportedly still be found while walking the island today.

By 1875, the Winnipesaukee Lake Cotton and Wool Manufacturing Company of Lake Village had acquired most of the island. When that venture failed, the island was sold off in shares to Joseph Varney of Wolfeboro, and development of the summer cottage community that exists today began taking shape, accelerated by the arrival of railroad lines through Gilford that made the Lakes Region newly accessible.

The summer community grew close-knit enough that in 1936, island resident Mary Donsker launched the first issue of the Welch Island Gazette — a weekly newsletter filled with neighbor news, social announcements, advertisements, and the small stories that make a real community. It's the kind of detail that reminds you Welch Island was never just a collection of scattered camps. It was, and still is, a genuine place.

Island Life Today

Today, Welch Island has roughly 60 homes spread across its acres of undeveloped forest and shoreline. Winter Harbor Yacht Club, founded in 1940, maintains its seasonal clubhouse on the island, adding a private-club dimension to the community. There are walking trails and nature paths for residents and their guests, vintage cottages built across multiple decades, and the timeless appeal of a life lived close to the water.

Because Welch Island is private, it's best experienced by staying at or visiting a property there, or by exploring the surrounding waters by boat. The main practical mainland access point is the Glendale Docks in Gilford (31 Dock Road), though those docks are reserved for Gilford residents and residential taxpayers and require seasonal permits. For renters and visitors, Welch Island is best enjoyed as a boat-by destination — and a fascinating one at that.

One cautionary note for paddlers: the open water near The Broads, just south of the island, can be exposed, choppy, and busy with boat traffic in summer. Kayaking in calm conditions along the island's sheltered sides is possible for experienced paddlers, but crossing open water requires care, a PFD, and an eye on the weather.

Welch Island Real Estate: A Rare and Storied Market

Properties on Welch Island don't come available often, and when they do, they tend to carry both serious price tags and serious character. The island's real estate history reflects a community where cottages have been passed down through families for generations — which is exactly what makes any listing here an event worth paying attention to.

Here's a look at recent Welch Island sales and the one property currently on the market:

What Welch Island Sales Tell Us About the Market

Look at the pattern across these sales and the current listing, and a clear picture emerges: Welch Island commands a premium, and that premium has been rising. From the $439,000 entry point of the 1960 vintage cottage to $949,000 for a larger waterfront home, and now $1,100,000 for the active listing — the island's combination of scarcity, history, and irreplaceable setting continues to push values upward.

Waterfront footage and acreage matter enormously here. The properties with the longest frontage and the largest lots have consistently attracted the strongest prices. And given that Welch Island has roughly 60 homes total, true opportunities to buy are genuinely rare — often years apart.

For buyers, the message is simple: when a Welch Island property comes available, it warrants serious and prompt attention. These don't linger. For sellers, the market affirms that island properties with generous frontage and authentic character are among the most desirable real estate on all of Lake Winnipesaukee.

Frequently Asked Questions

Is Welch Island open to the public?

Welch Island is not a public park or recreation area. The island has private cottages, private club facilities (Winter Harbor Yacht Club), and trails and beaches that appear to be for residents, owners, and their guests. There is no established public beach, public dock, or public trail system for casual visitors. Plan to enjoy it from the water unless you're staying at or visiting a property on the island.

Can you drive to Welch Island?

No. Welch Island is boat-access only — there is no bridge or causeway connecting it to the mainland. That's a big part of its appeal. Life there moves at the pace of the lake, not the highway.

How big is Welch Island?

Welch Island is often listed as 187 acres, though some real estate sources describe it as about 210 acres. Either way, it's the largest of the Gilford islands and generally considered the sixth-largest island on all of Lake Winnipesaukee. Roughly 60 homes are spread across its shores and wooded interior.

What makes Welch Island real estate so expensive?

Scarcity is the primary driver. With only about 60 homes on the entire island and a boat-only lifestyle that rarely comes to market, Welch Island properties represent some of the most irreplaceable real estate on Lake Winnipesaukee. Long waterfront footage, large private lots, mountain views, and historic character all add to the premium — as does the simple fact that no new island can ever be created.

What is the history behind the name "Welch Island"?

Local history attributes the island's name to Abraham Welch, one of the early claimants of the island in the late 1700s, along with Jonathan Moulton. By the early 1800s the island had changed hands and was being used to pasture sheep — a far cry from today's summer cottage community. Mary G. D. Donsker's 102-page illustrated history, The Story of Welch Island Through 1945, published in 1984, is the most thorough account of the island's early life and is held at the New Hampshire Historical Society and Gilford Public Library.
