You get fantastic views of the striking red cliffs that separate the meadow from the shores of Horsetooth Reservoir, but there are several short spur trails along the East Valley Trail that will take you down to various inlets. This trail is relatively flat and accessible and is also open to hikers and horses.

This half of the loop is on the reservoir side and generally flat with rolling hills through a meadow. You get great views of the hills where Arthur's Rock can be found across the valley from striking red cliffs closer to the water.

Historic site pointed out to us by Cameron Landis. Not sure what the purpose of this bench was, perhaps a place to sit and cool your feet when water flowed in this drainage. (Camโs guess)
