Summer in the canyon can be unbearably hot, with temperatures well into the 100s. During the trip I took, it never got much hotter than probably 80 during the day. All accommodations have private bathrooms. Meals are prepared at restaurants, hotels and at the homes of native Mexicans who cook up excellent dishes . Breakfasts often include eggs, potatoes and tortillas.
Lunch is usually sandwiches, fruit and granola bars.
Fresh bottled water is provided throughout the trip. Bring spending money for snacks, drinks and souvenirs. But, if you're in reasonable shape and have done a little biking before, you can make it. For those who get too tired on the tour, a support van is always nearby. Also be sure to bring padded bike shorts and helmet.
