One of the drawbacks of taking a Kilimanjaro group trip is that you may have to modify your walking speed to keep up with the others. If you’re a quicker climber, you may need to slow down to match the slowest climber’s pace. The slowest individual, on the other hand, may feel compelled to move quicker. This will be handled differently by tour providers. Some guides keep the group together at all times, while others let quicker climbers go ahead with one guide while slower hikers wait behind with another. Another downside is that pre-arranged group trips follow a set itinerary, which may or may not be convenient for you.
