Start at Niagara Falls State Park around 8:30–9:00 a.m., when Prospect Point and Luna Island are quieter and the autumn light is excellent for photos. The park is open year-round, and there is no general admission fee, though parking typically runs about $10–20 for the day depending on the lot. Allow roughly 90 minutes to follow the paths between the overlooks; wear shoes with good traction, since spray can leave the pavement slick.
Late morning, take the Maid of the Mist from the park for the closest broad view of the falls. The ride usually lasts about 20 minutes, but allow 1–1½ hours for ticketing and boarding; expect roughly $30–40 per adult, with rain gear provided. Its operating calendar can change in late October, so confirm the schedule online before setting out. If it is running, go before lunch to avoid the longest queues; if weather pauses departures, the park overlooks still make a worthwhile backup while you wait.
Continue to Cave of the Winds for a much more immersive encounter beneath Bridal Veil Falls. The attraction generally takes about 1½ hours including the elevator, walkways, and changing into the supplied footwear and poncho; late-season hours and access can be weather-dependent, so check same-day operations. Afterward, have lunch at Top of the Falls Restaurant, where tables look toward Horseshoe Falls. Budget approximately $20–35 per person, and allow an hour; service can slow during the midday rush, so a slightly late lunch works well here.
Spend the mid-afternoon on the Niagara Gorge Trail System, choosing the quieter Great Gorge Scenic Overlook area rather than trying to cover every trail. Allow about 90 minutes for a relaxed riverside walk, and be prepared for stairs, uneven ground, and exposed sections—October temperatures can drop quickly once the sun fades. Finish along Old Falls Street, an easy pedestrian stroll between the park and downtown restaurants. It is a good place for a warm drink or casual dinner, and the falls are often illuminated after dark; check the current illumination time and seasonal event schedule before going.
