3rd August 2011: This was the park I was expecting the least from but actually enjoyed the most. The recovering volcanic park is stunning. The last eruption of Mt Lassen was only in 1915 so you can see both old volcanic landscapes and newly created ones. There are hot springs whilst around you is still some patches of really thick snow. Very strange to be in a teeshirt wandering down a narrow path with snow either side higher than your waist.
