Connolly Ranch Education Center is hosting its 10th annual Earth Night Festival , a celebration of arts, music, movement, and nature, on Saturday, April 15th from 5:00 – 8:30 pm . Earth Night Festival is a well-attended, community event that welcomes guests of all ages to share in Connolly Ranch’s magic. Family festival-goers get to spend time with the animals, participate in nature-based activities, and dance under the stars to the rhythmic sounds of local bands – and in true Napa-style, enjoy good food and drink with friends.
