Cold Spring Harbor Turns Its Lights Down for Locals Every October

As TBR NewsMedia reported, Baylee Browning, a collections associate at the Whaling Museum, asked, "But who is the monster, really?" when the museum unveiled its Monsters and Mermaids exhibit in October 2024. She was talking about Moby Dick and Captain Ahab. Her question is a fitting one for October, when the museum's calendar looks quite different from its July calendar.

The difference shows up in event hours, ticket prices, and scale once Labor Day passes. The same street hosts a daylong festival in July and a two-hour evening program in October.

A July Festival and an October Evening at the Same Museum

Start with the Whaling Museum. Every July, the museum throws its biggest event of the year: the Sea Glass Festival, now in its fifth run, a full day from 10 a.m. to 5 p.m. with more than 30 coastal vendors selling handcrafted jewelry and coastal art. It is a family-oriented day, with online tickets at $18 and door tickets at $22, a Whale Sound Contest for kids, and a touch tank from the Long Island Aquarium. It is the museum's main fundraiser of the year.

October is the museum's back room. On the 16th this year, from 5 to 7 p.m., the museum runs Lights Out, where visitors carry blacklight flashlights through darkened galleries hunting for hidden glowing skulls before making glow-in-the-dark crafts in the workshop. Admission drops to $8 for adults and $6 for kids and seniors. There is no vendor tent, no touch tank, no aquarium partnership. It is a small, two-hour evening program for ages 4 and up. The museum has run adults-only after-hours events in the same window in past years, built around themed cocktails and nautical folklore.

Same building at 301 Main Street, with a daylong festival in July and a two-hour evening program in October.

Two Main Street Kitchens With Track Records

Two restaurants on Main Street round out the picture.

Grasso's Restaurant, at 134 Main Street, marked its 31st year in the village this past summer, with live music as part of its identity. One longtime description of the place called it a spot with a real "Hip Manhattan feel you don't find on Long Island," the kind of line that only makes sense if you have eaten there enough times to compare it to something else.

Sandbar, the coastal-casual restaurant also on Main Street, was named a winner in the FourLeaf Best of Long Island 2026 awards this year, taking Best Restaurant and Best American Restaurant honors, with Chef Julius Miranda named Best Chef under the guidance of Chef Emeritus Guy Reuge.

Both sit on Main Street, a short walk from the Whaling Museum.

The Trail Without a Festival

Away from Main Street, Uplands Farm Sanctuary offers the outdoor option.

The 97-acre preserve on Lawrence Hill Road, owned by The Nature Conservancy, was a working dairy farm from 1920 until 1962, and it still looks like one, with a silo and open meadows where cattle used to graze. Nearly 2.5 miles of marked trail wind from bird and butterfly meadows through deciduous forest and into a white pine-shaded ravine. The West Loop connects hikers to the 20-mile Nassau-Suffolk Trail, part of the Long Island Greenbelt, which runs south all the way to Massapequa. Parking is a small lot near the white silo, off Lawrence Hill Road, not far from the Billy Joel Park and Boat Ramp on Harbor Road.

Uplands Farm has no summer festival, no vendor tents, no ticketed after-dark program. It is a fall walk in the most literal sense: a meadow loop through goldenrod and milkweed, a shaded ravine, a trailhead in the same hamlet as the Main Street that hosted sea glass vendors in July. Dogs are not permitted on the property.

The museum schedules a large festival in July and a small evening program in October. Uplands Farm has no programming of either kind and is open from dawn to dusk, seven days a week.

Three Months Apart on the Same Calendar

The Sea Glass Festival runs a full day with more than 30 vendors. Lights Out runs two hours, with a blacklight flashlight and a workshop table, and admission is $8 for adults. Both are on the Whaling Museum's calendar, three months apart.

Grasso's has held its Main Street address for 31 years, Sandbar picked up its FourLeaf awards this year, and Uplands Farm keeps its trails open from dawn to dusk.

For this October, the date to write down is Lights Out at the Whaling Museum on the 16th, from 5 to 7 p.m., followed by a table at Grasso's or Sandbar.
