It appears there might be camping in
Tampumachay Colima. I have never seen it but I did eat at one of the restaurants there 20 years ago.
If you going through Comala make sure you stop at one of the
bontaneros. Either one of the two as you come into town or the ones right downtown. A few drinks and free food as long as you drink.
Outside of Comala is the
magic zone.
In Colima Colima there are the
The La Campana ruins/pyramids.
I love the area, I have been going there for 35 years, never camped there though, it is my plan to camp there in 12 years when retired.
Enjoy!
