How was it? It was simply fantastic. Our guide was Diane and she couldn't have been better. She was the perfect blend of being informative without being intrusive. Her delivery was great and her information was just what one would hope to hear on a trip such as this. The flow of the trip for those interested was 4-5 stops for about 5-15 minutes each once we reached the park entrance giving us a different flavor in each stop and each was very nice but the cherry on the top of the ice crean was the stop at 5,400 feet at Paradise Valley which was simply beautiful and the 90 minutes we had to walk around was a nice long time. We were there as a group of 8 from young kids to middle aged adults and the hike was no problem although it could certainly be more challenging if you chose to push it. The views on the ride as well were breathtaking (we had a relatively clear day although the top of the mountain was mostly obscured by clouds.) If you don't like heights (some of us on the trip weren't big fans) don't stress it for although there were several points where the bus is driving and it is a long drop down just choose the left side of the bus for 90% of that is on the right. Overall. it was a great day and as my son just said as he saw the picture of Rainier while I was typing this,,,,,ugh, I want to go back.
