Guam is a popular destination having historical landmarks and offering numerous sights of interest. During my visit to Guam with my family, the Cushing Zoo located in Tumon provided us the opportunity to see the native plant and animal life of Guam. We saw a leopard, crocodile and other creatures. You can take photographs of the excellent creatures. We enjoyed the under water world which is home to about wide range of animals including sea turtles, rays, sharks and one 500-pound grouper. Your children will definitely enjoy the shark feeding and don't forget to take your children to the touch pool, which includes an opportunity to touch a small shark and other creatures. May be it will help your children to do their vacation project. We also had that chance to touch the cute little sharks. There was also the Sling Shot ride for the adventurous types and all of us were really enjoyed it. Have a nice trip!
