Thanks for the tips, do you know of any public locations with forest and streams? She is wanting some with the water too, but we haven't found any good locations for it yet. She also likes a few spots in the Red Rock Canyon Trails.
Not exactly a stream but the place in the link above would be a great spot. It takes a little bit of work to get to though. Park by the Pikes Peak cog train station and then walk past the station up the hill, not the peak trailhead, but up the road that goes beside the train. The paved road has a sign that says local traffic only, but you can walk on it. if you follow that up the mountain it turns into a dirt road that runs parallel to the canon and train tracks. At some point there is a pipe gate across the road, its there that you want to veer left toward the stream there are several paths that you can see there. as you follow the stream up there you will notice that the bottom of the canon is filled with boulders and the water sort of meanders over, between, and under them as it makes its way down the mountain. I should note that there are warning signs there, about flooding and the land may be marked as private. Its used as part of a hiking running trail so its not like they are going to throw you out though. It would be better either early in the morning, or in the evening when the entire canon is in shade. During the middle of the day you have a mixture of bright sunny areas and deep shadows which doesnt work as well.
