This is a very busy attraction and rightfully so. We have done this trail 5 or 6 times in summer, fall and winter and it doesn't get old. The trail is a mix of earth paths and narrow metal walkways which are anchored to the canyon walls. Many squirrels and chipmunks will poke their heads out of cracks in the rocks as you head up to a series of waterfalls. Very exciting for the dog.
There are excellent view points from which to appreciate the power of the falls and feel the cooling spray. Neat cave to duck through, but you will have to wait your turn as space is limited and people are everywhere.
In winter, the spray from the falls freezes and creates an ice wall for people to climb. Gear and experience required. Cool to watch for a few minutes. Trail has slippery sections, but walking slightly to the side of the beaten path seemed to make it easier.
Continuing past the falls a few km is a nicely groomed trail that leads to beautiful green, turquoise and blue paint pots (small springs) with wooden boardwalks to connect them. Nice flower meadows and mountain backdrop.
Parking lot fills before noon so you'll probably have to park on the side of the 1A highway along with dozens of other vehicles. Great drive in if you take the 1A from Banff as there is no wildlife fence to keep the animals back from the road (like there is on highway 1). We almost always see a bear and some elk along this road.
