Estes Park's haunted hotel is the subject of one of YouTube duo Sam and Colby's full-length documentaries about ghost hunting.

Sam and Colby have over three million YouTube channel subscribers, and in one of their more recent videos, they take viewers inside the Stanley Hotel, which we all know was the inspiration behind Stephen King's The Shining.

The video is almost two hours longs, and has over four million views... So what exactly did they see? You can watch the video below, but maybe leave the lights on. #spookyszn
