My wife and I hiked and birded here five days in a row March 2014. We rented a nearby apartment at Room with a View. Every day was different, with new birds and new adventures. Staff and volunteers were helpful and friendly. Most of the other people on the trails were birders, also friendly. It's a beautiful place with a great variety of birds ( we saw almost 80 species), great flowers and scenery. I'd recommend the evening boat tour. If you'd like to explore the nearby Sonoita Creek Natural Area, stop in the state park natural area visitor center in the morning for a permit but check ahead for visitor center hours.
