tried to search to no avail. So, does anybody remember some pics that were posted a few (or 9?) months ago of some bikes in a cave, as I recall there was a bit of a scramble and then you got 'em right inside and road around with lights. Or something...
Typing that it seems a little far-fetched, so apologies if it's just in my mind.
Ramble over,

........................or I would think there is some foot path type way in but not as exciting, The riding through is a bit short but worth it. Heres a few more pics to get you in the mood
