This was a great hike very scenic and serene. The Sheep Pen Trail 2.5 miles has 3 Limpia Creek crossings. In the summer during the rainy season the creek will have 6" to 1' of water at all three crossings. After this there is a 700' ascent through a few long switchbacks to the loop. If you turn right at the loop intersection there will be a cistern at about a mile which will need to be filtered. If you turn right the vista 5700' is 1.5 miles. It was 75 degrees and sunny this day. I took a 3 liter camelbak and drank most of it. Well worth doing.
