الجواب وباللہ التوفیق

Quran e Majeed says it clearly

وَلَا تَقْرَبُوا الْفَوَاحِشَ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ ‘‘(انعام :۱۵۱)

Translation: And do not even go near shameless acts no matter that shamelessness is open or hidden.

قُلْ إِنَّمَا حَرَّمَ رَبِّيَ الْفَوَاحِشَ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ وَالْإِثْمَ ‘‘(اعراف:۳۳)

Translation: Say that my Rabb has declared shameless acts Haram no matter that shamelessness is open or hidden.

وَقُلْ لِلْمُؤْمِنَاتِ يَغْضُضْنَ مِنْ أَبْصَارِهِنَّ وَيَحْفَظْنَ فُرُوجَهُنَّ (سورہ نور:۳۱)

Translation: And tell the believing women to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts) 

In the light of these Aayaayt it is impermissible and Haram to go to such places where naked people are present.

واللہ اعلم بالصواب
