Then it was back underground again for the Great Masson Cavern. 

Finally, out onto the hillside and time for a group photo.

It was as if the teachers had no pity, 
down the hill, and then up the other side!
How could we look so happy?

Eventually we did get to the Youth Hostel.  
Food helped charge our batteries, and - as the weather was wet 
- we entertained ourselves indoors with the mattress game.
