Walden West is a great outdoor science school and also summer camp for little kids. During the school year, schools come here and each student pays $150 or so for a week, and it's well worth it. They get breakfast, lunch, and dinner everyday and field classes so they can learn about science and the earth. At night, there are story telling, and camp fire and the kids really enjoy it. They also learn to help conserve the earth's resources by not wasting food, and taking 2 minute showers.
For summer camp, toddlers and young kids come up and sign up for many activities that they want to do throughout the day. It's like a childcare center , and I'm not sure about the price for this. They also get fed snacks and they seem to enjoy the activities a lot.
