This is not really a 'danger tip' according to me, nor a warning. It is just a little 'You-should-know-tip' from my side.
The temple here has staunch religious beliefs, therefore they do allow only Hindus inside the temple (which according to me is an injustice to humanity on the whole). Also, they do not allow cameras, cell phones, and leather items inside the temple. So please do take care about these things and take required measures before you set out to visit the temple.
Puri gets very busy over the Christmas and New Year periods. I arrived the week before Christmas and struggled to find somewhere to stay. Puri is very popular with Kolkatans who you can spot a mile off as they walk around on the beach with giant belly's hanging out and man-boobs whilst the locals are stick thin. Be warned that Puri gets booked out during this period so you may want to pre-book to avoid disappointment.
I request all the Tourists to take professional help of the Nulias( the Tribal Fishermen) if you are new swimmer as there is QUICK SAND in some place of the Beach . These are tricky and known only to the local swimmers. For rs.20/- they will give you pleasure of wave bathing for about 30mts. Pleas bargain the rate they may ask for rs100/- also depending on your mood to enjoy the sea.
Otherwise, please bath in where all others are taking bath. Thats' the safest bet.
