I have adventured in Denali National Park three times for over forty days in the last thirty five years. Make a minimum of four trips plans in areas that match your vision, ability, and time BEFORE you leave the lower 48. Depending what month you arrive at the park you’ll be lucky if you get any of your four prior planned trips. That’s a bummer, but if you have done your homework prior, are flexible and patient in meeting your wants and needs (vision) things will fall into place, BUT be prepared you may not do everything you set your hearts to do on your first trip. My last trip you needed to get up in the EARLY am and proceed to the “caddy shack” before the crowd to check out with the “trips ranger” what areas are available in order to get a permit (first come, first served!)……Denali has been broke into many areas backcountry “blocks” and each have small “carrying capacity” numbers and this may be an issue with getting into an area you desire with the both of you.
Water crossing are dangerous so treat them with respect as you would the bears.
