During this time of year, tubes always pack the river but quickly seem to disappear. This is also dependent on what part of day as they don't show up until after lunch and disappeared before 5.
All in all, great 4 or 5 hour trip and with lots of local outfitters, easy and fun access for both beginners and the seasoned pro.
Bigfoot Canoes and Guadalupe Canoe Livery seem to be the heavy hitters out here.
$5 charge to park at Nichols Landing park but there was no attendant collecting or honor box when I was there.
