In 2004, on the 30th anniversary of the publication of "D&D", "Dungeon" magazine published a list of "The 30 Greatest "D&D" Adventures of All Time" and ranked "Expedition to the Barrier Peaks" as 5th. Judge Bill Slavicsek felt the adventure was a "classic clash of genres". It was not something he felt should be done often, but it made a "memorable diversion". Judge Mike Mearls described how he felt the first time he read "Expedition to the Barrier Peaks". "I had this terrible, terrible conflict within myself to immediately tell my friends about it at war with a maniacal, desperate drive to keep it hidden at all costs." Judge Keith Baker was most impressed with the adventure's art. He liked that it came with a separate book of art; in particular the before and after illustrations of the carnivorous plant with a "built-in bunny lure". This was later featured in a Wizards.com "Ask Wizards" segment. According to the "Dungeon" editors, the adventure's defining moment was its froghemoth creature, and its full page color illustration.
