Travel insurance is recommended and can be purchased from many different providers. The tour operator has provided the following link to their suggested provider:

Comments from Sean our Tour Operator (Not necessarily the view of Los Amigos)
People are free to get insurance on their own, but I would recommend they look for the 3 biggest factors:
1. Trip Cancellation up to 100% of trip cost
2. Trip Interruption up to 150% of trip cost
3 Travel Delay up to $200.00 per day.
If they don't offer all 3 of these, they are not worth it.
