The Hike

The hike is easy and is the perfect trail to take children and dogs. Dogs are allowed on the trail as long as they are leashed. The trail is relatively flat with plenty of shade because you are walking through a canopy of oak trees. Kids will love the fact that the trail is next to a stream the whole way and furthermore there are lots of places you can walk down to the water. I saw kids sitting on rocks in the middle of the stream and hopping back and forth.

The Waterfall

The word (waterfall) is used very loosely here. At around 1 mile into the trail, a dirt path leads down to the water. Here you will find a small man-made waterfall. Your kids will be way more impressed than you, but it is a serene place to take in nature.

Returning to Your Car

Unfortunately, as of March 2021, the waterfall is the end of your hike. They are currently doing construction and the rest of the trail that heads towards the dam is closed. However, if you are in the Inland Empire and looking for a short hike to take kids or dogs I think Big Dalton Dam Trail fits the bill. We saw birds, squirrels, and crayfish and we heard frogs in the stream. The trail would even be okay to hike in the summer because it is short and has lots of shade and since you are already in Glendora after your hike, you could stop at the World Famous Donut Man for a strawberry donut or a Tiger’s Tail.
