not knowing what Blue Lagoon was, my friend and i decided we'd go as all the taxi drivers kept asking us if we wanted to go there. So we went early-ish and arrived at the crystal clear blue waters, perfect 'reveolver' type music playing and ropes that you can swing into the water with.
However, before coming we had domr mushies and decided we needed to be in a clamer place. So we made our way up the mountain and into the cave (which is free entry). We began our trip in the cave and was mesmerised by the huge, golden sleeping buddha in the middle.
Unfortunately we decided that renting a torch would be a waste of money - we were so wrong. A torch is definitely necessary when going into this cave.
The cave was amazing to trip in, though even if you're not tripping it's beautiful and huge. You can walk for days in the cave if you're not worried about getting lost.
I had the best time visiting blue lagoon and Phu Kham Cave. My only suggestion is to go really early in the morning to avoid all the young drunks who take over in the afternoon (not really what you want to be around if you're tripping).
Laos is incredible, but Blue Lagoon just made me realise how incredible it is.
Another tip, if you can, try to walk the 8km back into town. you pass villages, schools, people and small cafes. when you get too tired you can always hail a tuk tuk to take you back or maybe just get on the back of someone's motorbikes (that's what we did)
