Chisos Basin is a high flat area (flat is relative here), in a rise above the Chihuahuan Desert. So it's dry, bu then it's high, so has a little different plant life than you would normally find. As a matter of fact, some you don't find anywhere else except in the Chisos Basin.
The main hike is the Window which is really rather unusual, as you are surrounded by high peaks, except for a certain part - a Window into the world outside. I sorta felt like I was in Shangra La, but didn't have to go through a blizzard to get there!
So imagine mountains all around except for this little "Window" and you have a good picture of the Chisos Basin and the charm of the area.
Well that and there was a mountain lion the night before right behind the basin store....rats, why weren't we there last night!!!
Further down the road is the Rio Grande Village close to - yep, you guessed it - - the Rio Grande.
BTW, there's a $5,000 fine if you cross the river. I have no intentions of doing anything like that cause my little dog, Siggy, doesn't have papers!!!
But because we're close to the water....and trees - apparently there was a ranch here early on where they dug ditches to flood irrigate the area - there are birds and I mean lots of 'em.
Big Bend has some very unusual climates - desert, mountains and riparian - all different and unusual - very interesting to visit.
