We are planning a trip to GNP in late July, flying in to Great Falls 1 pm on the 19th and leaving mid day from the same on the 27th. Have just booked St Mary Lodge (much to my dismay due to the rate but will keep calling every day to get into Many Glacier or something else more reasonable in that area of the park) for 5 nights. There are three remaining nights and we could do Waterton for one or two nights and/or Two Medicine area for one or two nights. We could also shorten our stay for St Mary area to 4 nights to accommodate more days in Waterton and/or Two Medicine areas. We are traveling with a 20 year old and and a 17 year old who have experienced hiking challenging hikes (Banff, Jasper, Yoho - Lake O'hara) last summer so we want to hit the best day hikes but would like to include a couple of other activities they might enjoy to break up the hiking a little bit. I could hike all day every day but my 17 year old daughter will revolt if we repeat last years vacation with no breaks! I am looking for suggestions on how long to stay in each area, activities other than day hikes (we do not hunt or fish). If anyone can suggest places to stay in the Many Glacier area that may not yet be booked, please do! Thanks for your ideas in advance.
