Mona Island is an amazing place to take a vacation. Some of the animals living there can't be found anywhere else in the world. There are fascinating beaches and caves to explore (探险). The sea around the island has colorful fishes.
Mona Island is very small. The government of Puerto Rico (波多黎各) takes care of the island and has made it a natural reserve. That means the island's animals and plants are protected from being harmed by people. Mona Island is different from most places because people are not allowed to live there. Only a few park workers are able to stay.
The park workers' job is to keep Mona Island safe and wonderful. Rules must be followed on the island. One rule is that only 100 people at a time can visit the island. That way, the park workers can make sure the land and animals remain safe.
On the island, visitors can go to see Mona Island iguanas (鬣蜥) which live only on Mona Island.
Also, visitors can come to the island to have a close look at many kinds of fishes. They can dive(潜水) far below the surface. They use special tools to be able to breathe under the water. Through the clear water, visitors can see the bright colors of the fishes.

After a full day of fun activities, visitors can take a rest, listen to the night sounds, and watch the stars in the huge sky. The stars are easier to see. Visitors say that watching the stars is amazing. It's the perfect end to a perfect day.
