(WJBK) - It was a day of family fun at this lake for a family of bears.
This video was taken last Thursday in South Lake Tahoe, California.
You see mama bear and her two cubs swimming alongside some human beachgoers and paddle boarders. The bears didn't bother anyone and no one was hurt.
But wildlife experts say it's a good idea to stay away from bears no matter how cute they may look.
This video has now been seen online more than 10 million times.
