Lake Winnipesaukee Rentals: Towns, Shores, and Seasons

Lake Winnipesaukee fills 71 square miles of the Lakes Region at 504 feet above sea level, in the foothills of the White Mountains. It is about 21 miles long and 1 to 9 miles wide, with a maximum depth of 180 feet and more than 250 islands. Lake Winnipesaukee rentals are spread around the eight towns on its shore. A drive around the lake meets them in order, clockwise from the south: Alton, Gilford, Laconia, Meredith, Center Harbor, Moultonborough, Tuftonboro, and Wolfeboro.

The Lake

Long Island, at 1,186 acres, is the largest island and connects to Moultonborough Neck by a bridge. Bear Island, at 780 acres, is the second largest. In the middle lies the Broads, the wide, open stretch with no islands, from Center Harbor in the northwest to a point between Alton and Wolfeboro in the southeast. The lake drains west through a dam at Lakeport and down the Winnipesaukee River to the Merrimack.

The lake normally freezes in the last week of December, and the ice is often thicker than 18 inches. A pilot at Emerson Aviation in Gilford declares ice-out when the M/S Mount Washington, the lake’s big excursion ship, can reach all five of its ports: Alton Bay, Weirs Beach, Meredith, Center Harbor, and Wolfeboro. The call has historically come in mid-to-late April. In 2026 it came on April 12. The earliest on record was March 17, 2024. Ice can linger in coves after the call.

Boating Rules

State law sets the speed limit on Winnipesaukee at 45 miles an hour by day and 30 from half an hour after sunset to half an hour before sunrise. Every boat must slow to headway speed within 150 feet of the shore, docks, swimmers, rafts, mooring fields, and other boats. Anyone 16 or older driving a motorboat over 25 horsepower needs a New Hampshire boating education certificate, so ask the Marine Patrol whether a certificate from home counts before you take the wheel of a rental’s boat.

The Shore Route

Alton Bay

The shore begins at the lake’s southern tip, where Alton Bay narrows to a village at the water. Tourism has been the town’s main business since the middle of the 19th century, and the lake’s first Mount Washington was launched here in 1872. The ship still calls at Alton Bay.

Mount Major rises above the bay to 1,786 feet. Its trailhead is a signed lot on NH Route 11, 4.2 miles north of the village. The Main Trail reaches the summit in 1.5 miles with about 1,150 feet of climbing. The Brook Trail, at 1.7 miles, and the Boulder Loop, at 1.6, are the alternatives. The Forest Society, which owns the mountain, warns that the upper ledges are steep and dangerous when wet or icy and suggests the Brook Trail on those days.

Gilford

North of Mount Major, the shore reaches Gilford and Ellacoya State Park, about 600 feet of sandy beach on the southwest shore with a boat ramp and a view across the water to the Sandwich and Ossipee mountains. Parking is limited on busy weekends and holidays, so book a day-use reservation. The state takes them up to 30 days ahead. Pets are not allowed in the park. In 2026 the beach was staffed until September 20.

Laconia and Weirs Beach

Laconia, a city of about 16,900, lies between Winnipesaukee and Lake Winnisquam. Its lake village is Weirs Beach, at the channel to Paugus Bay. The name comes from the fishing weirs that colonists found at the Abenaki settlement of Aquadoctan. Weirs Beach has the largest public beach on the lake. The railroad reached Laconia in 1849 and brought summer visitors to the Weirs.

Two boats leave from here. The Mount Washington sails to its five ports from late May through October. The M/V Sophie C, launched in 1945, is the oldest floating post office in the United States and delivers mail to island residents through the summer. Its 2026 schedule ran from June 21 to September 12, with stops at islands including Bear, Three Mile, Cow, and Jolly.

Laconia Motorcycle Week, which the city calls the oldest national motorcycle rally in the country, fills nine days in mid-June. In 2026 it ran from June 13 to June 21. If you want a quiet week near the Weirs, check the rally dates before you book.

Meredith and Center Harbor

North of the Weirs, Meredith Village is at the head of Meredith Bay, where US 3 meets NH 25. Lake Waukewan, a smaller lake, forms the village’s western edge, and Bear Island lies offshore. The Mount Washington calls at Meredith. In winter, when the ice is thick enough, the head of the bay holds a pond hockey tournament and an ice fishing derby. The hockey moves to Lake Waukewan when the big lake is too thin. Center Harbor, the next town, is at the northwestern end of the Broads and is another of the ship’s ports.

Moultonborough

Beyond Center Harbor is Moultonborough. Moultonborough Bay is an 8-mile arm, and the bridge from Moultonborough Neck leads to Long Island. Red Hill rises to 2,020 feet. The Eagle Cliff Trail climbs 0.6 mile to a lookout and 2.1 miles more to a fire tower with views of Winnipesaukee, Squam Lake, and the White Mountains. Its Bean Road trailhead holds only five or six cars, so arrive early.

The Ossipee Mountains rise to the east. On their slopes is Castle in the Clouds, the estate the shoe manufacturer Thomas Plant built in 1913 and called Lucknow. Its 6,300 acres have walking trails kept by the Lakes Region Conservation Trust and long views over the lake. In 2026 the house was open daily from May 23 to October 25.

Wolfeboro

The eastern shore road passes through Tuftonboro and reaches Wolfeboro, at the head of Wolfeboro Bay, where NH 28 meets NH 109. The town’s motto calls it the oldest summer resort in America. It bases the claim on the colonial governor John Wentworth, who built his country estate beside what is now Lake Wentworth. That lake drains by the Smith River into Winnipesaukee. Wentworth State Park has 50 acres on its shore for swimming, picnicking, and fishing. Its parking is limited, so reserve a day-use spot up to 30 days ahead. The Mount Washington calls at Wolfeboro too.

Seasons

July and August are the lake’s months. The Mount Washington is sailing, the mail boat is making its island rounds, and the state beaches are staffed.

Much of the water season lasts into September. The mail boat finishes in mid-September and the state beaches stop staffing around the same time, but the Mount Washington sails through October, and Castle in the Clouds stays open until late that month.

April is the month not to come. Ice-out may fall early in the month or late, ice fishing shacks must be off the lake by April 1, and the cruises do not start until late May. Winter itself is a separate trip. Thick ice brings the Meredith Bay events, but they depend on the weather each year. State guidance for the lake gives 6 inches of ice as a minimum for a snowmobile and 12 for a pickup, and warns that currents near inlets and springs keep the ice thin.

In summer, check the state’s Healthy Swimming mapper before a swim. The environmental agency has issued cyanobacteria warnings for parts of Winnipesaukee in recent summers, and a warning means keeping people and pets out of the water in that area.

Local Rules

Each town sets its own rules for vacation rentals. Gilford writes its rules into the zoning ordinance. Any rental of up to 30 days needs a conditional use permit from the planning board. Overnight guests are limited to two per approved sleeping area, plus two more, and the cap applies to everyone on the property between midnight and 8 a.m. Each approved sleeping area allows one car, parked on the property. A loft reached by a ladder does not count as a sleeping area. A notice by the front door must give a contact who answers around the clock. Ask any host in any town how many guests and cars the permit allows before you plan a group.

Many lake houses are offered by the week in summer, Saturday to Saturday. Some island houses can be reached only by boat. Before you book, ask whether the house is on the mainland or an island, where you park and how you cross, whether a dock or boat slip comes with the stay, and whether the shoreline is sand or rock. If a boat comes with the house, ask its horsepower, since that decides whether the driver needs the state certificate.

The questions to ask a host cover water access and parking. For a big party sharing one house, the large group guide covers how to book it, and a gathering of relatives can start with the family reunion guide.
