Hi All,
My husband and I are planning to take a trip in the fall from Nova Scotia to Niagara Falls, Ontario by way of USA. What is the best route to take, how many hours. we would like to go through the Adirondacks, (I think that is what the mountains are called). Any feedback would be great.

Aren't the Adirondacks in NY state?
Nowhere near Nova Scotia. And, not exactly on the way from Nova Scotia to Niagara Falls, Ontario.

Where do you live?

For starters, maybe try a Mapquest search.

OB1

Get to New Brunswick, then Moncton, then through Sussex to Highway 172. Take ferry to Deer Island.

Cross Deer Island, ferry to Campobello, over bridge into Maine at Lubec.

Highway 1 to Ellesworth and side trip to Bar Harbor and Acadian National Park.

Back to Highway 1, side trip to Boothbay Harbor, back to Highway 1, to Portland.

Turn inland. Via backroads get to Interstate 93, to St Johnsbury.

Little roads to Montpelier and then Burlington.

Ferry to New York, on through Lake Placid, Saranac Lake (Adarondacks) and on to Watertown, south to Syracuse and NY Thruway, to Niagara USA and Niagara Canada.

A straight line from Amherst, NS to Niagara Falls <I>pierces the Adirondacks following a path from Burlington, VT to Watertown, NY</I>.

To the OP: I looked at a map to try to recall anything in the way of routes I've taken, that would really make them better than others, and I can't really think of <I>anything</I>, when going in that direction <I>across the grain</I> of the upper northeast, which would make any place I've been (or haven't been) somehow <I>better</I> than other options.

I'm sure you should generally adopt BAK's suggestion/path above, and perhaps tinker with it based on personal preferences and whimsical notions along the way.

Hope you have a nice journey.

Very interesting. I have learned a lot.

The easiest way to enter the Adirondacks is through the border crossing just outside of the city of Montreal. The border crossing is about an hour outside of the city. Just before you cross into the US, I would highly recommend you explore the Circuit de Paysan - a beautiful route that delights the senses with bakeries, cideries, local produce, cheeses, etc.

BAK's suggested route above is great if you have a lot of time. Some of the prettiest spots I have seen. And Deer Island in itself is interesting. You can cross directly from Deer Island and land in the US as there are two ferries that run from the beach (or there used to be).
