It's GREAT BassMajician that you want to take your son on a outdoor/fishing adventure. The Nueces Canyon is a super place to visit,hike,and fish. Best time to fish that area is mid spring,summer,and fall. There are several camping parks. Cooksey's just outside of Camp Wood is a super place to camp. The park is super clean and has some great rules that are enforced by management. The park also has river access to the Nueces. If you have a kayak or a boat with a 25 horsepower or less you can launch there at the park. There is limited bank space there but just outside the park there is plenty of bank space. Great scenery all around and there are a couple of good restaurants in Camp Wood to eat at. There are also some public areas to fish leaving Camp Wood on River Road. There is a park called Twin Sisters and they charge a fee to day fish. I think the fee is $5.00 per person. There is also bank areas up FM 55 towards Uvalde that are good. Another camping area that allows day fishing is Chalk Bluff which is on FM 55 outside Uvalde. Some of the places I fish are private but I do well on both the private and public areas. Hope you are able to make your trip. Lifetime memories await you and your son.
