Although the COVID-19 pandemic forced a temporary halt on construction, the ride was not delayed from its targeted opening period. In June 2020, shortly after major construction had commenced on the attraction, Mystic River Falls would begin testing and sending rafts around the course. On July 5, 2020, Mystic River Falls would soft-open and begin loading members of the public. A few weeks later, the ride had its official grand opening on July 21, 2020.
