Where to backpack in late November?

Grand Canyon

+1 Arizona.  Summer is usually the wettest season, but sometimes the monsoon rains (remnants of Pacific hurricanes) last into October. Water-wise,  I’ve been drenched before in a few Octobers in AZ , but also once experienced drought (though someone in this board said there was water later in November)

If you’ve got the $, New Zealand.  Fly into Christchurch, take the bus or train to Arthur’s Pass, hike the TA or another another route south, catch the bus and/or hitch back to Christchurch depending on how far you get.

Grand Canyon is great in late Nov but nights are still long and permits require at least a bit of advanced planning.

The Los Padres National Forest is ideal in late November. You can contact the LPFA for more info.

I’ll put in my vote for Pategonia.  It will be early in the season down there, but both Torres del Paine and Los Glaciares are unbelievable.  You can hike the full circuit in Torres del Paine with very little planning (besides booking a flight).  It won’t be a full wilderness experience, as there are refugios along the way, but it is certainly spectacular.
