Medical form can be downloaded from here: Download link
This is a copy of our medical form for your reference only; the idea is for you to know which questions we’ll be asking in our online form in case you plan in booking in pairs or groups. That way if you cannot have everyone with you as you go to make the online reservation, you’ll know their answers to the questions. Please do not email us this form back!
Please note that medical form has to be answered by each participant in a group booking.
For your own health, safety and enjoyment, it is important that you are of a suitable physical condition to participate in the tour activities. The questionnaire is to help us ensure you have a safe and enjoyable trek. Most medical conditions will not exclude you, so please be completely upfront about whatever condition(s) you have so that we can be best prepared to accommodate you. You will be days away from any hospital and we need to know your accurate situation. Please, do not lie on your medical form. We will do everything we can to help you join the tour. If your health status changes between when your booking is approved and when you join us here, it is your responsibility to advise us of that so that we can review your booking if necessary. If we find at any time that you have not completed the form honestly and in good integrity, we have the right to cancel your tour without refund.
Be advised that this tour is not for those with limited outdoor/trekking experience, those in poor medical condition, nor is it for children or expectant mothers. If you answer yes to any question, our specialist team will e-mail you for more details. This is routine, and you should not worry that it means you will not get on the tour.
Finally, be detailed in your answers, otherwise your reservation will be rejected – “regular walking”, “going to the gym” are not considered detailed. You must have some previous outdoor experience such as trekking/hiking, or climbing (not just indoor wall), caving, etc.
