I like to travel abroad. Usually I travel by plane. Traveling by plane is expensive but fast. I visited Italy last summer. I did not miss the flight and arrived a flight on time. The custom officer checked my luggage and I filled in the form and declared foreign currency. I paid duty and booked the hotel. I was careful so I was afraid that someone would steal my wallet or I would lose my luggage. I stayed at the hotel for two days. I visited local attractions: castles and museums. But I wanted to try extreme sport. I bought a ticket for an excursion to the mountains. My group walked throught the forest and camped on the river bank. There were high mountains nearby. We climbed the mountains for several hours. It was difficult, but mountain climbing is wonderful. Then we rode mountain bikes. My travel was tiring but exciting.
