Dear Sarah,
This summer, I went with my parents to Sochi to rest.
On the first day we went to the Black Sea and then went there every day.We bathed, sunbathed, built castles. I went on a water slide and I really liked it.
Back in Sochi, we went to the Dilphinarium. I really liked the dolphinarium. All the animals there played with balls and catching fishes. And fast dolphins fun jumped through hoops and from springboards. They turned out to be very cheerful and friendly, they could be stroked. We took pictures with them.
At the end of the rest in Sochi, we went back to the oceanarium. Some fish in it were familiar to me, but most were strange and incomprehensible. I especially liked the long fish moray, similar to a snake. And in a transparent tunnel a real shark swam slowly.
When we left Sochi, I felt a little sad. After all, I got an unforgettable experience there! I decided to definitely go back there yet.-
