The area, some 100 mts below JLN Marg, has been planted with 80 varieties of big and small host plants. The area has some 900 trees and treated waste water is regularly sprayed on them to keep the moisture in the area high.They have developed waterfalls and ponds decorated with stones brought in from Nathdwara and Haridwar. So come February you need to visit the Butterfly Valley with your camera for a date with the fast vanishing delicate creatures.
