Holy places like Sangam ( at the bank of river Ganga and Yamuna ) , Navagrah mandir in Rambag , mankameshwar temple of lord shiva in the bank of Yamuna , hanuman mandir in the Sangam area , Hnuman mandir in civil lines e.t.c are the places to never forget to visit.
Parks like , Bhardwaj park in Katra , Minto park in kydganj , khusro park near the junction , Chandrashekhar Ajad park near the civil lines are the beautiful garden's to visit.
Some other historical places like patthar girjakhar and Anand bhawan are also in Allahabad.
Allahabad University and high court are also some places to vist.
City is very crowded.
People arrive here due to the , one of the best holy event known as 'Kumbh' which takes place every year in the month of January and February.
