Ahoy there, ye gentlemen o’fortune! Shiver me timbers! Avast ye, ye lily-livered landlubbers, and be listenin’ to what I be sayin’, an’ you’ll be gettin’ to hear o’ some rich booty...
By the powers! Are ye all loaded to the gunwales? Settle ye down! There’s gold doubloons an’ pieces o’eight a-waitin’ for some scurvy dog, me hearties. All ye have to be doin’ is takin’ this ‘ere Treasure Map, findin’ the X, then ye be repairin’ straight to the treasure chest, only a league away!
I’d fetch it meself, but wi’ me wooden leg I’d be in Fiddler’s Green afore I got there....!
Get me some grog in the Admiral Benbow when ye’re done – I be wantin’ me share o’ the treasure, or ye’ll all be gallows meat! I be makin’ sure every son of a biscuit-eater gets keelhauled if ye don’t turn up!
...Aaar, Jim lad...I can't keep this going any longer...!
The treasure chest is a wooden(ish) box with brass trimmings, and contains a number of nautical knick knacks plus a cache of gold and silver coins, including dozens o'gold doubloons (well, one)!
The intermediate cache - identified by a distinctive "X" on the box - contains the "treasure map", or at least the co-ordinates for the final location. Please leave in the box! The intermediate site (the co-ordinates given above) is just outside the Admiral Benbow Inn: in the film Jim hands over the treasure map here.
The final cache is near to the treasure location in the film (where else!).
It's about four and a half miles in a straight line to the treasure from the Benbow: much longer (12.5 miles) but highly recommended is the coastal path. If you don't want such a long walk, there are buses from Castletown to Port Erin - or you could drive, of course! The approach to the treasure is by an easy surfaced path, and access is possible at any time. Don't get ambushed!
Note that the path from Port Erin to the final cache is closed. Approach from the Bradda Glen end (i.e. heading south towards Port Erin from Bradda) and you should have no trouble with the paths.
