Everything worth doing.Within 20 minutes.

The founding vinifera winery in the Finger Lakes — Dr. Frank planted the first European varietals here in 1962 and changed what the region could grow. Hillside tasting room above the west arm pours dry Riesling, Rkatsiteli, and estate sparkling that trace back to those original plantings. Ask about the reserve flight if you want the wine history seriously delivered.

Panoramic hilltop tasting room above the west arm — small cafe on-site, deck seating when the weather holds. Riesling and Chardonnay lead the list; the Ingle Vineyard bottlings are the ones to try. Go before noon on a Saturday if you want the deck without a wedding party parked next to you.

The north-east anchor winery on Route 54 above the Penn Yan end of the lake. Family-run since the mid-1980s — Riesling, Vignoles, and a well-regarded Cabernet Franc program. Broad porch for a slow-pour afternoon. Pairs cleanly with a Windmill Market run on a Saturday morning.

Four-generation family winery on the north-west slope above Branchport, with history dating back to the late 1800s. Vidal Blanc ice wine is the estate calling card. The pond and picnic lawn make it one of the better slow-visit stops on the west arm — bring the dog and sit outside.

The formal waterfront restaurant at the very north tip of Keuka — lakefront dining room, outdoor deck, and a lakeside patio. Elevated American menu that leans into local produce and lake fish when in season. Book the deck for sunset in July; the dining room is quieter in October.

A north-end ritual stop on NY-54A west of Penn Yan — soft serve and fried chicken from the same counter since the 1960s. Locals stop after a lake day; the line moves fast and seating spills onto the lawn. Get the chicken tender basket with a chocolate dip cone to go.

Organic frozen custard made with duck eggs from the Ancona flock on the property — sweeter and richer than soft serve, closer to a French crème anglaise. Small farm shop with a picnic patio out back. Ranked among the best ice-cream stops in the country and worth the drive north.

"The Switz" — a boat-up institution with two outdoor decks over the water, docks at the restaurant, and live entertainment most summer weekends. Casual American menu, long-running family operation. Come by boat if you can; the wait for the deck is real on a July Saturday.

Dockside restaurant right on the south end of the lake — small dining room, seating on the water when it's warm. Steaks, seafood, and a strong lake-view case for the sunset seating. Reservations advised, and ask for the deck when you book.

Lakeside restaurant with boat slips out front and extensive outdoor seating on the water — casual menu, cold beer, and the come-in-off-the-boat crowd once the sun drops. Live music on select nights. Walk-ins on the porch, reservations for the dining room.

Hilltop taproom off West Lake Road with the widest view of any brewery on Keuka — the arm of the lake below, the ridge across it. Weekend food trucks, live music on select summer nights, and a crowd by mid-afternoon. Go early or aim for a Thursday.

Small west-side brewery on Route 76 south of Hammondsport — cellar-door pours, a barn tasting room, and the kind of pace where a flight takes as long as you want. The quiet counterpoint to Steuben's crowd on a Saturday afternoon.

Farm brewery on a hilltop above Penn Yan — orchard-adjacent, expansive lawn, and one of the better sunset patios in the county. Wood-fired pizza most weekends; house sours worth ordering. Bring layers after seven, even in July.

Seven miles of multi-use trail from Penn Yan to Dresden, following the outlet stream that carries Keuka into Seneca. Waterfalls, mill ruins, and the old Fall Brook rail alignment. Easy for bikes end to end; the shady middle mile past the falls is the section to walk. Dogs on leash.

The south-end village waterfront park at the tip of Keuka — floating dock, swim area, seasonal concert lawn, and the departure point for the Pat II tour boat. Walk to Hammondsport Square from here in three minutes. Bring the kids for the Thursday-night summer concert series.

621 acres on the west arm at Bluff Point — swim beach, campground, picnic pavilions, playground, nature trails, and a paved boat launch with pump-out. The largest public lake-access complex on Keuka. Reserve campsites through NY State Parks well before Memorial Day; the loop fills first.

The Saturday farmers market between Penn Yan and Dundee that draws a regional crowd — 250-plus vendors of local produce, baked goods, Amish and Mennonite crafts, and prepared food. April through December, Saturdays only, open by 8 a.m. Come hungry; leave with a pie.

Marina and boat-rental operation at 35 West Lake Road on the south-west arm — pontoons, ski boats, and slip rentals. Booking online for summer weekends fills two weeks out. Bring an insurance card; they check.

The narrated Keuka Lake tour boat that runs from Depot Park — one-hour lake cruises, some sunset departures, and private-charter options. The classic first-timer's move for the south-end afternoon. Buy tickets an hour ahead in season.

Hammondsport's museum of aviation and motorcycle pioneer Glenn H. Curtiss — vintage aircraft, motorcycles, and early-flight artifacts from the town where American aviation grew up. The classroom-quiet counterpoint to the wine trail. Two hours is enough; the flying-replica shop in back is the surprise.

Regional boating museum on the Hammondsport waterfront — antique wooden runabouts, canoes, and Finger Lakes boat-building history in the old winery buildings. Free admission, donation encouraged. A rainy-day pair with the Curtiss Museum across town.
