A real nature study... it started out as a short 3 mile hike but we ended busy snapping at every moving creature. it took a little longer than the 2 quick two hours planned . It was just teeming with life along the creek... bugs, butterflies, dragon flies, beetles, toads u name it, we saw it... it was a very very nice & pleasant hike and the Double Arch Alcove at the end of the hike did not disappoint.. This was a fitting end to our visit to Zion National Park. Utah..
