My next stop was at the Saguaro National Park. It is just a day park with nice picnic areas and hiking trails. The entrance to the park was $10 per vehicle but I got in for nothing thanks to my geezer card (National Park Senior Access card). There is a one way 9 mile loop that takes you through the cactus forest. I decided to take a few pics of the various types of cactus to show you. I will do my best to identify them for you.

Teddy Bear Cholla.
If I got any of them wrong please let me know. The nine mile driving tour was very nice and the scenery was beautiful. Too bad the cacti weren’t in bloom. That would have been spectacular.

Oh sure, I am not going to correct you on cactus. I can’t even identify the plants in my own yard!
I beg to differ on the teddy bear cholla identification. I’m not sure but I think it is a hanging-chain cholla, certainly not a teddy bear.
