Being that small it is very easy to go around Jordan and enjoy the fascinating landscapes, in Jordan you can be in the middle of a forest and in less than one hour you can be in the middle of a desert, or from a thousand meters above sea level to 390 m. below sea level, you can even enjoy swimming in the warm Dead Sea in a cold winter day with heavy rains in Amman half an hour away.
