Last year Katie and I visited the Hershey Gardens in late May for one reason and one reason only, butterflies! This Friday the Hershey Gardens opens it's newly renovated Butterfly House which houses more than 200 free-flying butterflies, over 20 different species from around North America. We had a great time trying to find the different varieties of butterflies and the guides inside the house are very helpful pointing out the hiding feeding spots behind leaves and rocks.
The butterfly house is open daily from 9am-5pm, the warmer the weather the more active the butterflies will be. Admission is $12 for 12 and up, $5 for kids 6-11 years old and FREE for those 5and under. Make sure you check around for coupons, I think there is a BOGO in the current Entertainment Book (2010). Good luck and have fun!
