Where can I view aurora?

Excuse me, could you possibly enlighten me on the whereabouts where one might have the opportunity to observe the mesmerizing spectacle of the aurora? I've heard tales of its breathtaking beauty and have long desired to witness it for myself, yet I'm unsure of the most suitable locations. Could you perhaps provide me with some insight, perhaps detailing a few of the most renowned spots where the northern or southern lights can be reliably viewed? I'd be most grateful for any guidance you might offer.
