( CNN ) -- A popular sightseeing destination in Australia is boldly going where no tourist attraction has gone before -- by offering audio tours in the Klingon language . Starting August 22 , Star Trek fans and those who are fluent in Klingon can visit the Jenolan Caves National Park and take a self-guided audio tour in Klingon through the `` Nettle Cave . '' Currently offering audio tours in eight languages , Nettle Cave is part of one of the oldest cave systems in the world and has about 150,000 to 200,000 visitors annually , making it one of the most visited caves in Australia . `` We thought it would be neat to add another language , perhaps a fictional one , '' says David Hay in charge of Cultural Initiatives at Jenolan Caves . `` We considered adding dwarfish or elfish , but then decided to add the second most spoken fictional language in the world after Esperanto , which is Klingon . '' How to speak Klingon . Hay says the language addition is n't completely out of the blue . In the early 1990s , two writers of `` Star Trek : The Next Generation '' visited the caves and decided to name a transport vessel , the USS Jenolan , in the 1992 episode , `` Relics . '' In July , two Klingon scholars -- Michael Roney Jr. and Tracy Canfield -- visited the caves from the United States and translated the current English audio tour of the caves into Klingon and recorded it in a Sydney studio . Speaking in the Star Trek language , Roney exclaimed `` lH , qar ' a ' '' ? when he first visited the caves to express their beauty , according to a statement released by Jenolan Caves Reserve Trust . The Klingon language was first created in 1979 for `` Star Trek : The Motion Picture . '' by James Doohan , who played Scotty in the sci-fi series . Star Trek producers later consulted linguist Mark Okrand to develop the language for `` Star Trek III : The Search for Spock '' and subsequent other films . The `` Klingon Dictionary '' created by Okrand went on to sell hundreds of thousands of copies over the years . Currently , the Klingon Language Institute has an estimated 2,500 members in 50 countries . `` What I think is happening is that people are very interested in the language and we have created a portal into it , '' says Hay . `` This is an opportunity for others to listen to Klingon and make it available for those who interested in it .
