We started with a 30-min drive to the hike at Twin Falls and up to the Upper falls. I believe there were 2 hours reserved for the hike, but we spent a bit more as not everyone in our group were that much of hikers. Me included, although I was not the one to cause some delay :) It is a doable hike, just be prepared for some not so steep but clear ascents that take more time. Gourgeous views as promised, so definitely worth it!
Afterwards we drove to the Snoqualmie Falls. I would have prefered to have little bit more time there to have a visit at the Salish Loddge & Spa or walk the short trail nearby. By googling Salish Lodge & Spa it seems like you would like to spend a night there, though :)
On the way to Snoqualmie Falls we also did a brief stop at the village and saw the railwaystation, too.
This was a nice hike + visit to the Snoqualmie Falls with not too early morning and I believe is good value for money. There was some water and snacks (fruits etc.) reserved for us. The guide Susan was a nice person and thank you for also our chaffeur John!
