23. USA, Hawaii Volcanoes National Park

It seems to be incredible when we think about 2 active volcanoes which are part of National Park, Hawaii Volcanoes National Park to be more specific. Card was sent by Alyssa, really nice Postcrosser I had chance to trade with. Park was established in 1916. As said before it encompasses two active volcanoes: Kīlauea, one of the world's most active volcanoes, and Mauna Loa, the world's most massive subaerial volcano. The park gives scientists insight into the birth of the Hawaiian Islands and ongoing studies into the processes of vulcanism. For visitors, the park offers dramatic volcanic landscapes as well as glimpses of rare flora and fauna. In recognition of its outstanding natural values, Hawaiʻi Volcanoes National Park was designated as an International Biosphere Reserve in 1980 and a World Heritage Site in 1987.

18. China, Lushan Mountain

Postcard was sent by Winkey Yeung, chinese postcards collector that I met on Postcrossing facebook side. This marvelous card shows territories of Lushan Mountain during the cooler seasons. As sometimes called Mount Lu or just Lushan, is situated in the northern part of Jiangxi province in southeastern China, and is one of the most renowned mountains in the country. Moreover it's also a part of Lushan National Park, a UNESCO World Heritage Site since 1996, and a prominent tourist attraction.

10. United Kingdon, Bath

I got this card through one of the tags on Postcrossing Forum from lesera. Bath is a city in Somerset, South West England. The city became a spa with the Latin name Aquae Sulis ("the waters of Sulis") c. AD 60 when the Romans built baths and a temple in the valley of the River Avon, although oral tradition suggests that the hot springs were known before then. It became popular as a spa town during the Georgian era, leaving a heritage of Georgian architecture crafted from Bath Stone. Bath became a World Heritage Site in 1987. The city's theatres, museums and other cultural and sporting venues have helped to make it a major centre for tourism with more than one million staying visitors and 3.8 million day visitors to the city each year. The city has two universities and there are large service sector, information and communication technology and creative industries.
