Adults. Sunrise Valley Wetlands is an aquatic jewel on the border of Reston and Herndon. Twilight is a time of transition as diurnal animals shelter for the evening, while nocturnal animals begin their nighttime activities. Enjoy a leisurely stroll through the wetlands as we try to catch glimpses of nature’s “shift-change”. Reservations required by May 4. Co-sponsored by Reston Historic Trust.
