5-7 night backpack trip in July/August… GLACIER NATIONAL PARK ( http://www.nps.gov/glac/index.htm ): From the web site, "Glacier is a backpacking paradise. The park consistently ranks as one of the most popular backpacking parks in the NPS. Famous for its towering mountains, pristine alpine lakes, abundant wildlife, and its 700+ miles of trails, this amazing place is growing in popularity each year.” Permits are a gamble - few choices, difficult routes. THE WIND RIVER RANGE ( http://en.wikipedia.org/wiki/Wind_River_Range ): From a related web site, "The Wind River Range is quite possibly the single most dominant range of the hundred or so that make up the Rockies in the United States. Exceptionally long, wide, high, rugged, and remote, the Winds (as they are affectionately known) are little known outside of the hiking and mountaineering communities, but to many they are clearly the quintessential Rocky mountain range." Permits are not required for small groups.
