travelling is the most exciting thing in the world. first of all, it lets us discover the world and to see different countries, experience their cultures and traditions. moreover, we enrich our knowledge about life in general and particularly about ourselves. travelling also gives us an
opportunity to meet new interesting people, learn new languages and develop our skills. that’s why i’m trying to travel as much as possible.
the best trip i’ve ever had in my life was to france. although it happened two years ago, but i still recall this wonderful time with a great pleasure. i
went there with two of my friends and it was really the right decision, because we travelled by coach and the journey took a long time. we were playing cards on the way, singing songs and joking all the time. as we arrived we checked in a hotel not far from the center. we were exhausted but in a
good mood.
the first day in paris was fantastic. it was a bus tour around the city called open tour. we got on a bus at the nearest stop. it was amazing that it stopped in front of all sights, so we could get off and walk around the most famous places. we took thousands of photos of eiffel
tower, the louvre, arch of triumph and other monuments. we were impressed by the number of tourists and the beauty of the places we visited. we spent 4 other days in paris, but this first time our impressions were thrilling.
the next days we visited plenty of museums and had some time for
small shopping to buy souvenirs. last evening we went on a small excursion by boat. it was amazing to be on board and to see all the sights again as if they were saying goodbye to us.
thus, it was fantastic time and i hope to come back to paris one day to get the same marvelous emotions
there.
