How busy can I expect the park to be on a sunday in october?

I think they're usually not too crowded. I wasn't able to go on a Sunday in OPctober last year so I'm not sure, though. But, I think I remember reading in trip reports that they're not too crowded.

Wow talk about planning ahead, sundays are normally a good day to go thru October.

Sundays in October are empty. I mean, empty. Most everything is a walk on or near so.

I know, isn't it wonderful? It's my favorite time of the year to go to KI, especially if the weather is nice.

I love Sundays in October!!!! The weather is usually pleasnat and the lines are almost always very short. Avoid Saturday nights though!
