Lassen is one of the most unusual places in California, yet is relatively little visited, partly because it is a long way from most other famous natural attractions in the state. Also, access is restricted due to the heavy snowfall that this area receives - the park may be fully open for only 3 months of the year though is at least partially accessible in any month. It is amazing to visit when the road is being ploughed after a hard winter as although the machines leave the surface clear, the vertical walls of snow at either side may tower many feet above, enclosing the road in a dazzling white canyon.
