minerals coat the rocks
	
	
	
	
	
		now why would anybody do that?
	
	
		hefty prices for a dip
	
	
		long waiting lines
	
	
	
	
	
		  
		  
		  
		  
		  
		  
		  
		  
		  
		  
		Travel agencies advertise this spa in Iceland's southwest as a must do.
  
		 
  
		Hence the Blue Lagoon draws scores of visitors who happily  
		pay the hefty entrance fee for the favour to take a dip in the silica and sulpher rich warm waters.   
		These minerals also give the  
		water its typical blue color. 
  
		 
  
		The water is actually a waste-product from the nearby geothermal plant Swartsenge. 
   
		The  
		high mineral content prevents the 
  
		recycling of the water, so it is dumped in a nearby lavafield. But the minerals make  
		the lava impermeable and hence they have to keep digging new  holes called lagoons. Not quite sustainable me thinks.
  
		 
  
		The  
		Blue Lagoon company has invested heavily and positions the spa as a high end luxury product. SInce 3 out of every 4 visitors  
		to Iceland take a paid dip here it seems a winning strategy.
  
		 
  
		We visited in July 2015, but did not get wet. Instead we strolled  
		along the borders of the blue ponds.
