If you're looking for views of the city skyline, you'll have to take a ferry to the Toronto Islands. Make sure that you buy a ticket to one end of the chain (ie. Ward's Island) and walk to the other end (where you can catch another ferry on the return), as the walk is very pleasant and covers a number of different landscapes from urban to wilderness.

For fall colours:

1. Marie Curtis Park (foot of Etobicoke Creek, with memorial to Hurricane Hazel Victims); take the TTC Islington 110 A/B bus to the last stop, and walk west to the park. If you ignore the tended, goose-poop covered lawns and head to the waterfront, you'll discover natural areas with hiking trails that are well-worth exploring.

2. High Park is always lovely and worth a trip to explore its many natural areas.

3. The Boardwalk at Woodbine beach (east end of Toronto) is lovely in the fall; you may get views of the downtown core. Not off-the-beaten-path, but wonderful.

1. Take the Queen 501 streetcar for its entire length. It's the longest streetcar route in the city, and it covers an amazing diversity of neighbourhoods. Though the entire trip takes about 1 1/2 hours, it's well worth the time.

2. Walk the Annex. It's the neighbourhood to the west and north of the University of Toronto's St. George campus. (That's a simplification of the area, but Toronto residents will forgive that). This is probably the best place to see Toronto's Arts and Crafts residential housing.

3. The "old" gay ghetto (Church St. from Bloor south to Dundas) is vibrant, lively, and friendly, and has many points of interest on route;

4. Visit the Toronto sculpture garden on King east of Yonge. It's a very small park now surrounded by highrises, but typically contains two or three interesting exhibits; not many people frequented this when I lived in the city.

Too many to list; pick any stretch of Dundas, College, or Bloor in the old City of Toronto and walk on it for awhile, and you'll see what I mean. Toronto's main attraction is its diversity, not internal cohesion.
