Hiking up to Mirror Lake is an easy mile walk and when you get there it’s more than worth it. The reflection on the “lake” (which isn’t really a lake at all, but is a meadow some parts of the year) is beautiful. I wish we had been there at a time you could get a full reflection of Half Dome, but the water wasn’t high enough. Oh well! I think we got pictures of North Dome or Basket Dome or Something Dome.. anyway, it was pretty.
