Mineral King Road is only open for the non-snowy parts of the year. The road is bumpy, narrow, windy, and long...if you are willing to sacrifice 1.5 hours of driving, you will be rewarded with spectacular scenery. You will pass some lovely Sequoias (not nearly as large as the giants found in the rest of the park, but fascinating nonetheless. At the end of the road, you are greeted with a vista of Sierra Mountain splendor. Particularly beautiful in the fall, the trails lead past some lovely shades of orange and yellow mixed among the pine trees. We saw some snow-capped mountains, waterfalls, flowing streams, old cabins, and lovely valleys. We hiked the Mosquito Lakes Trail, but there are trails of all lengths and skill levels. I suggest the Farewell Gap Trail to Aspen Flat for an easy 2 mile, 1 hour hike. There are port-a-potties at the trail head.
