The tour starts normally in Colima (CLQ airport); typically, you fly to Mexico City and from there on to Colima with Aeromexico. Transfers from and to Guadalajara airport can be arranged in some cases (request).
The tour requires no to very little physical effort; all viewpoints are reached by car or with only short hikes.
