Next to the Royal Palace and the Temple of the Emerald Buddha, there is a vast open ground called Sanam Luang or Thung Phra Men.   There may not be much going on, but Sanam Luang has some historical significance.  At the time when Bangkok was first established, the ground was a rice field and was sometimes used as a location for a royal crematorium, Phra Men in Thai. The ground was, thus, otherwise called as ‘Thung Phra Men’ which means the crematorium ground. In considering that the name was inauspicious, King Rama IV had the ground renamed as ‘Thong Sanam Luang’, or the Royal Ground, and the rice farming there cancelled.  The area is used for various public events, most notably for political activities during election time.  It is still also used as a crematorium for the high-ranking Royal family members.

If you have a few hours to kill in the afternoon, there are a few places around the Grand Palace that is worth seeing.

The City Pillar Shrine.
According to an old Thai tradition, a city pillar had to be built upon the establishment of a new city. King Rama I had the Bangkok city pillar erected near the Temple of the Emerald Buddha on Sunday, 21 April, 1782, with the city’s horoscope inside. The original pillar was made of cassia wood known as Chaiyaphruek, measuring 75 cm. in diameter and 27 cm. high. In the reign of King Rama IV, the old dilapidated pillar was replaced by a new one made of the same kind of wood, measuring 270 cm. high and standing on a base of 175 cm. wide, sheltered by a Prang-shaped shrine as it appears today. The shrine also houses images of protective deities including Thepharak, Chaopho Ho Klong, Phra Suea Mueang, Phra Song Mueang, Chaopho Chetakhup and Phra Kan Chai Si.

Thailand has beautiful place very much if you come to tour in thailand , assure that ,you do will not be defeated certainly.

Sea Kayaking has recently taken off in Thailand as a hugely popular activity. There are a number of companies, all with experienced and trained staff, who are willing to take you on an adventure, as you explore the sights of Thailand from the sea. It is a fantastic and unique way to view the country. Sea Kayaking caters for all types of people; for beginners or for those who are a little more confident or experienced; for those wishing for just a little light kayaking as they see the sights, or for those wishing to have an adventure and explore uninhabited islands. Sea Kayaking offers an extraordinary and exciting way for you to discover your own Thailand.

There are different types of water transportation available, such as inflatable craft, or fibre glass canoes with a roof to sit on, but the most popular type and probably the best way to enjoy this experience is with the traditional kayaks, using nothing more than muscle power (although it does not necessarily have to be too strenuous!). No other way will allow you to intricately explore the rocky coastline or inlets of small islands so closely – other water transportation can be too noisy, too fast or too clumsy. Sea Kayaking in Thailand enables you to connect with the stunning scenery whilst touring the beautiful coastline, observing the wildlife on land, in the sky, and under water from a unique vantage point.

There are different types of trips one could take in a sea Kayak. For example, one could take a leisurely visit to a National Park, watching the wildlife as you paddle below, an amazing experience which is a favourite with many. There are also trips to uninhabited islands, which allow you to become intrepid explorers for the day. You can even spend a few days exploring the coastline further and camping overnight (if you don’t fancy camping more comfortable accommodation is also available!). There are also many caves, or Hong(Thai for room) to be explored, the narrow sea Kayak perfectly formed to be able to investigate these natural phenomenon. There are many and varied tours, all a perfect way to sample some of the most beautiful scenery Thailand has to offer, from white sandy beaches to tropical vegetation. All fitness levels are catered for, and there will be a trip that everyone will enjoy. Sea Kayaking in Thailand is a liberating and rewarding form of transport, enabling one to escape the hordes of tourists on land, and enjoy a tranquil and unusual way to sightsee Thailand.
