Intrepid Travel is suspending tours departing until at least May 31.
The move echoes cancellations announced by G Adventures.
Intrepid said: “The safety and wellbeing of our travellers and staff is our priority, therefore, effective Monday 16 March Intrepid Travel will suspend all tours until at least 31 May 2020.
“Given the unprecedented impact of coronavirus we have updated our booking conditions and cancellation policies to adapt to the constantly evolving nature of this pandemic.”
Anyone booked on a tour originally due to depart until the end of May will receive a credit of 110% to put towards an alternative tour with a departure date before April 30, 2022.
The operator added on its website: “At this stage all tours departing from 1 June 2020 will continue as planned.
“If there are changes, or if your trip is cancelled, you will be notified directly by our customer care team or your travel agent.
“If you choose to cancel your tour departing from 1 June 2020, you will receive a credit of monies paid to use towards an alternative tour with a departure date before 30 April 2022.
“For future travel full payment is due 21 days prior to the departure of your trip.”
