Your surgeon will have the best advice for your particular situation. However, 2 weeks is pretty early after surgery to be hiking a mountain! After a blepharoplasty, patients typically experience swelling and bruising that starts to resolve within 2 weeks. When you stress your body and elevate your blood pressure within the first 6 weeks after surgery, you are likely to experience more swelling, and possibly more bruising. If this is okay with you and your surgeon, and you have been advised how to handle this on vacation, then you should be fine. Also keep in mind that mountain = altitude. Make sure your surgeon knows your complete medical history so that he/she can advise you appropriately and determine if your type of anesthesia will influence the decision to hike a mountain. Good luck!
