Organizers of this festival hoped to attract 15,000 attendees when it started in 2012; they got 33,000, and 50,000 the next year. The festival features a wide-ranging slate of artistic performances, from theater to dance and music, at venues throughout the East End, including a magnificent and rare Spiegeltent from Belgium. This was the first Fringe Festival in Upstate New York, and now it's one of the biggest in the country. Its free outdoor spectacle performances are a unique feature that you won't find at most other festivals.
Cobb's Hill provides a great panoramic view of downtown. Located on the corner of Culver and Monroe, it is an easy walk from the cafes on Park Ave. Large duck pond, baseball diamond, tennis courts and a nice (although steep) trail to the top of the hill, where the reservoir is located. A path popular with runners circles the reservoir. Adjacent to Washington Grove, 26 acres of old-growth Oak–Hickory forest right in the middle of the city.
At the confluence of the Genesee River and the Erie Canal, the park is a great place to step off onto the Genesee Riverway Trail, the Genesee Valley Greenway, and the Erie Canalway Trail (see below). It's also known for its golf course, one of the major public courses in the area.
Most famous for its hundreds of lilacs, Highland Park is the site of the annual Lilac Festival. Even when the lilacs aren't blooming, though, there are countless other examples of Rochester's horticultural tradition. There is a Sunken Garden behind the Warner Castle, and the Highland Park Bowl, a natural amphitheater, hosts concerts and films during the summer. Adjacent Beikirch Park hosts the county's Vietnam Veterans Memorial and the AIDS Remembrance Garden.
The conservatory holds a number of more exotic plants that wouldn't survive outside in Rochester, including desert and tropical species. Open year-round and a wonderful refuge from the stark winter landscapes.
Maplewood is often overlooked, but it's an important piece of the park system. A long, thin park designed by Olmstead as Seneca Park West, it has three distinct areas. The southern park is home to the beloved Maplewood Rose Garden and (with a hike down to river level) has lovely views of the Lower Falls. You can also access Lower Falls Park and see the Middle Falls via the Genesee Riverway Trail. Be sure to check out the sculpture called "The Seat of Remembering and Forgetting". At the northern end you'll have nice views of the Veterans Memorial Bridge and the river gorge, and a pedestrian bridge lets you cross the river to Seneca Park. In between is a wooded trail with some recreation space.
Manhattan Square
This urban park near the Strong Museum features a unique concrete amphitheater with a distinctive metal superstructural sculpture, some play equipment, and a public outdoor skating rink that (in warmer months) converts to a reflecting pool with fountains. It's a major gathering space for Rochesterians and hosts the ROC Holiday Village every December.
