There are a lot of public parks big and small in downtown Toronto where you can just chill and relax after you're tired from sightseeing. Here are some of my favorite places:
- Grange Park: right in the middle of downtown, next to the Art Gallery of Ontario. It's usually filled with artsy students (it's right next to Ontario College of Arts and Design) and young families. Great place to people watch.
- Riverdale Park: on the peripherals of downtown, you get a fantastic shot of Toronto's skyline from here.
- Centre Island: just south of the Financial District, the park itself is free but you do need to take a ferry to get there that costs $7ish. It's a large urban green with beautifully manicured lawns, beaches, and a gorgeous view of the financial district.
- High Park: a little bit outside of downtown, and you need to take the subway (High Park or Keele Station), but it's a massive park and you'll find lots of secluded places for you to chill.
- Queen's Park: in the heart of downtown area, and right next to the Ontario provincial parliament. It's not big nor secluded, with lots of foot traffic, but it's an ok place to catch your breath if you're tired.
- Trinity Bellwoods Park: a little bit west of the downtown area, and you'll need to take a street car to get to it from downtown. It's a large-ish park with lots of open space. You'll see tons of young people and young families playing sports and having picnic here in the summer.
You can just plop these parks name into Google for the best way to get there. All of these places are accessible by public transit + walking and should take you no more than 15-45 minutes to get to from downtown. Centre island requires taking a ferry.
