I love finding new parks and a friend from church told us about Sterne Park in Littleton- its tucked away on some side streets and it is AWESOME! It has a huge lake, a little river and lots of minnows and ducks! There is a playground and a pavilion and lots of shade which is a plus.
My kids played for hours trying to catch minnows in their test tubes and they amazingly succeeded!
Love the little trail along the river bed.. fun exploration!
