So I've been reading that it is not very reasonable to make a car trip from Talkeetna to Denali NP in (1) day (stay in Healy instead?). However, this is where I find myself. Looking to travel the end of May: so I know you can only get as far as Tolklat River (53 mile marker)...yes? Is this doable in a day, granted a very long day? Just know, I'm used to driving a 3 hour round trip.
