Was just thru there last year.  We went in thru Death March and out thru Veron/Camel/Eag/Cub/Heronshaw etc. to Kawnipi.

The route from Heronshaw to Delahey is a great section of the park.  Very lightly travelled, and good fishing throughout.  Nice campsite on Cub.

The Death March is, to quote Stumpy, "just a long walk in the park".  The trail is easily visible and there's not much up or down to it.  It's just long.

If your plan is to enter via Heronshaw and exit the Death March, you've chosen a great route.  I highly recommend it!

I'm heading into the park in the AM myself.  Might see you on Kash, depending on when you pass thru.  I'll be in a tannish solo canoe wearing the Filson Packer hat.
