Two hours would be a perfect time to walk the trail up to the falls. Hopefully it has rained a day or so before you arrive to see the beautiful waterfall in action. Enjoy.

There is a small water park on the north side of the park I believe Victoria Park Pool 2 Adam St, Truro, NS B2N 6J3 (902) 895-7078 //goo.gl/maps/LuMP75T5B7v Kids can play there

Yes you may swim there at your own risk

The main trail into the park is very popular. On it, you will pass Jacobs ladder (180+ wood plank stairs), after the ladder you can cross a bridge over a small river (you’ll see a gazebo with benches inside). Or continue on the main route where you’ll come to two sets of waterfalls (upper and lower). Near the back end of the park there’s a loop called “vibert trail” that contains two fairly steep hills that often used for training. Starting at the pool, “hemlock trail” is popular as well. This all said, you can walk the entire park between 1.5-2 hours. The whole park is full of well groomed trails, rivers intertwined, and handmade bridges. All trails are well marked, so don’t worry about navigation.

You can walk to the waterfall and back to the parking lot with a stroller, but to make a circuit you have to do stairs.

The map shows 6.4 km

There are several sets of stairs leading to many different trails I'm not exactly how many, some sets have more stairs than others. One of the main attractions is called Jacobs ladder, and it has a lot of stairs, it leads to the water falls and then back around. I see quite a number of people using it for a good workout.! You might find more information on line about the park. I hope this helps you some.

Yes... lots of people walk there dogs, but they must be on a leash.
