Gay Eitel of the Taylor Creek Visitor Centre told Barcroft Media it was fortunate the season was coming to an end.
She said: "Real photographers take pictures that can seem to show the bears are close to them in the shot. The fact is they are using high-powered long lens equipment so they are actually far away from the animal."
"We have found that the general public have been going out with iPhones and suchlike, and trying to recreate those pictures a lot closer to the bears."
"These are wild animals. They may have got used to people because of visitors to the park, but they are still potentially very dangerous."
"We have had staff out and saying to people it probably isn’t a good idea to get a picture of your 3-year-old next to a bear cub when its mother is just a few feet away eating fish."
