Near Apadana and French castle is a musium but it is off in monday , i can not inside it because i went to Susa in Monday ;)
Apadana is near Danial Tomb , it is not big place like Perspolis . Great Dariush come here more in winter for see people and listen what they said .
It's quite easy to reach Shush. Either from Ahvaz or from Andimeshk.
There are taxis, minibuses & shared taxis for this purpose.
In my case, I arrived in Shush from Ahvaz but out from Shush to Andimeshk.
You have to ask around or the Apadana Hotel staffs in Shush could give you informations where to wait for the minibuses or the shared taxis or even can call you a yellow cab for the excursions or to the nearest towns.
The reputed tomb of the Prophet Daniel, real or supposed, is situated on the east bank of the river Sha'ur; immediately to the east rises the great mound of Susa. It is a building surmounted by a pineapple cone in white plaster and It is clearly of no great antiquity. It is typical of this part of Iran and also of Iraq. If we can believe the Book of Daniel, the Prophet was closely associated with Susa during his lifetime; it was at Shushan the Palace that he had his vision of the ram with two home, one of which was higher than the other. According to Islamic sources, the Muslim Arabs discovered the coffin containing the Prophet's remains in the castle of Susa when they occupied the city in the seventh century AD. On learning of this discovery, the Caliph Omar decreed that the river Sha'ur should be temporarily diverted and the coffin interred in the river bed; the stream was then to be allowed to resume its normal course (one may compare the story of the burial of Alaric in the bed of the Busento in Italy). Rabbi Benjamin of Tudela, who visited Susa in 1165, has a different story to tell; he claims that he saw the coffin containing the Prophet's remains suspended by chains from the center of a bridge over the river. It would appear that while the remains had been interred on the eastern side of the river, the inhabitants on that side had enjoyed such unparalleled prosperity that it aroused the envy and jealousy of those on the west side. Feelings rose so high that fighting almost broke out, but a compromise was reached whereby the remains were interred for a year, first on the west side and then on the east side, and so on. When the Seljuk ruler Sultan Sanjar (who died in 1157 AD) heard of this arrangement, he said that it denoted a certain lack of respect for Daniel's memory and gave orders for the coffin to be suspended from the center of the bridge, so that those on either bank could receive equal benefit.
In Susa can not find anything have dangerous for person but weather in summer is very HOT an is better dont travel to Susa ,
Less tan an hours drive from the pleasant desertcity of Shush you find Choqa Zanbil, a beautifull ziggurat witch is the best preserved monument from the elamite kingdom. It has deservedly got its place in the unesco world heritage list. Now the whole building, made of adobebricks are completely uncovered and rises some 25 meters above the surrounding dessertplain. But it was, believe it or not, buried in sand for 2500 years until an oilvompany found it. Around the ziggurat some simple, but mindboggling adoberuins are uncovered. Itis part of the ancient city of Dur Untash, founded by king Untash around 1300 BC. When you walk around this ancient building, look ffor the bricks with inscriptions in the lower level at the western side. You probably wont be able to read it, it is wtitten in the ancient cuneiform script, but it is mindbogling anyway.
Taxi for charter are easily found in Shush, and should not cost more than max 50.000 rials.
