Does anyone know of any companies that offer walking / hiking tours in Denali. There will be 4 of us and we are not really too keen on walking on our own. We don't want to be on the bus for 8 hours and would really prefer a ranger or guide. We are looking for a easy to moderate day hike. I know the park offers discovery hikes but it appears you can only reserve that a day or two before. I will definitely check it out upon arriving in Denali (June 21st) but want a back-up plan for the next day. I am open to any suggestions or recommendations.
