So, you want to take a river raft trip, but you don't have 7 days to go through Grand Canyon. How about a half day trip from Glen Canyon Dam down the Colorado River to Marble Canyon and then back to the dam? Fun for the whole family, and it's a day trip! There are also combo trips that include raft/helicopter and raft/slot canyon tours.
If you go:
Make reservations well in advance. This is a secured area, (the federal dam has security restrictions) so only billfolds and cameras are allowed. Leave everything else in your locked vehicle.
