Went to Mt Rainier (driving, not climbing) on 22 Aug 2010 (Sun) for an hour (but spent hours driving to there).
This was my 2nd trip. 1st time, I went there was in July 2008.
Road to Sunrise visitors centre
Sunrise visitors center - highest & nearest point where you can view Mt Rainier (by driving)
Could stay in a hotel at Sunrise visitors center if wanted to.
Went up by this - The lastest Hyundai Sonata
