Ontario County
Ontario County was established in 1789 and became an early administrative center for a much larger portion of western New York. Today it sits in the western Finger Lakes, anchored by Canandaigua and Geneva and shaped by glacier-carved lakes, productive farmland, wineries, colleges, historic homes, and village centers. The Thruway and major state routes connect the county with Rochester and the broader Finger Lakes region.
Visitors can tour gardens and historic estates, swim or boat, hike waterfall glens, explore Ganondagan, taste local food and wine, and spend time in Canandaigua or Geneva. County parks such as Gannett Hill and Grimes Glen add easily accessible outdoor options, while Victor and Farmington provide major shopping and services. The result is a county that blends resort-town energy, working agriculture, and everyday regional convenience.

Frequently Asked Questions.
Start with the questions people actually ask about Ontario County — from signature attractions and outdoor access to local travel, weather, and community life.
Start with Sonnenberg Gardens & Mansion State Historic Park, Grimes Glen Park, and Ganondagan State Historic Site. Together they show the county’s best-known mix of local character, outdoor scenery, and history. Add one downtown or village walk and a local meal rather than trying to cover the entire county in a single day.
Good starting points include Grimes Glen Park, Gannett Hill Park, and Harriet Hollister Spencer State Recreation Area. Check current weather, trail, park, and seasonal conditions before you go, especially during winter, spring mud season, or periods of high water.
Family-friendly options include Sonnenberg Gardens & Mansion State Historic Park, Roseland Waterpark, and Ganondagan State Historic Site. These choices give families a mix of hands-on learning, local identity, and recreation.
Begin with Ganondagan State Historic Site, then add Ontario County Historical Society and Granger Homestead & Carriage Museum. These places connect the county’s architecture, settlement, industry, transportation, culture, or natural history to the communities you see today.
Ontario County is served by 21 ZIP Codes under the coverage used for this guide: 14424, 14425, 14432, 14443, 14453, 14456, 14461, 14463, 14469, 14471, 14475, 14504, 14512, 14518, 14532, 14537, 14547, 14548, 14561, 14564, 14585. Confirm any street-level mailing address with the official USPS ZIP Code Lookup.
The main routes include I-90 / New York State Thruway • US 20 • NY 5 • NY 14 • NY 21 • NY 96 • NY 332. Use 511NY for construction, closures, incidents, and winter road conditions.
Expect four distinct seasons. Summer supports parks, water recreation, festivals, and longer daylight; fall brings foliage; winter can bring snow and ice; spring can mean wet or muddy trails. Check local forecasts and 511NY before longer drives or outdoor plans.
Try Kershaw Park, Grimes Glen Park, and Canandaigua Lakefront. Public parks, waterfronts, trails, historic streets, and scenic overlooks are often the easiest way to experience the county on a small budget.
Consider New York Kitchen, Rio Tomatlan, or Nolan’s on Canandaigua Lake. Pair your meal with a walk through Canandaigua or another nearby town center.
Yes. Put Sonnenberg Gardens & Mansion State Historic Park on one half-day, reserve another block for Grimes Glen Park, and use Ganondagan State Historic Site as your history anchor. Add one local meal and one town or village walk so you have room for weather, seasonal hours, and travel time.
It combines two important lake communities, Canandaigua and Geneva, with vineyards, historic sites, farm country, waterfalls, county parks, and major regional services. You can get a strong Finger Lakes experience without having to drive across the entire region.
