Kauai Reopens to Tourists with New Travel Rules in Place Photo: Michael Barajas/Shutterstock.com. The island of Kauai is planning to reopen to tourists after a halt forced by a surge in the coronavirus. Kauai was the only Hawaiian island to opt out of the state program that allows trans-Pacific visitors if they produce a negative test before arrival. Instead, the island had required all travelers to undergo a 10-day quarantine. Kauai began a version of its own entry program on Tuesday. Inter-island travelers flying to Kauai can participate in the state’s Safe Travels program to get out of quarantine with the pre-arrival testing program and wait at least three days before coming to Kauai.
