That's what they call the mules that take visitors to the canyon floor and back. Canyon mules are specially raised for the purpose of taking guests on this trip. As the mule trainers say, "This is not a Disneyland ride. It's a real adventure."
Mules are trained from 1 to 3 years before they are deemed ready for carrying guests on the trip. Some mules are never judged up to the task. These will become pack mules. A healthy respect for the edge is required of these animals. Mules are a born from a mother horse and a father donkey. (I'd like to see making THAT happen). They can see all 4 feet at the same time, which is essential given the tricky trails into the canyon.
The guided tours begin at Bright Angel Trail. An overnight adventure cost about $350 er person. There are also one day options.
They say that anyone who enters the canyon will be forever changed. Many people carry their own burdens into the canyon and leave them behind.
Take a mule ride down the canyon. There are two options - a one day trip takes you halfway down the canyon, gives you a nice view and then takes you back up to the top. The two day trip takes you all the way to the bottom, where you camp for the night and then back to the top the next day. The mules have sure footing on the narrow paths. It's a little scary at first but is a lot of fun. Make reservations far in advance as this kind of trip books up quickly!
One day mule trips head to Plateau Point and back and overnight trips go to Phantom Ranch for the evening. Although the trips are easier than hiking, participants must be able to mount and dismount without assistance and must weigh under 200 pounds.
Mule travel is also expensive and runs about $300 per person for the overnight trip and about $120 for the day trip
