If you are worried about Covid, this is not the excursion for you! I called all the rafting companies to find the safest. They did not keep their word and keep busses at 50%, nor did they enforce masks in the facility or on the bus (people removed their masks in front of the guides, or even talked to the guide the entire ride back- with his mask pulled down!). Some employees wore ill fitting masks that rarely covered their faces.
We enjoyed our rafting trip, but for the reasons above, I can not recommend this company. I worry about my safety and the safety of their employees.
