Although only myself and one other walker that accompanied our guide, it was such a great trek. A little dubious how I would be on an 8 Km trek in a river ankle high in cold water, and deeper at times, but heck, it was great. So eased I bit the bullet and went for it. Due to only being the three of us, it was great, the pace was easy, didn't have to wait for the slow ones so to speak, so it was at our own pace. Not a difficult trek, very gradule incline, so not too taxing. Glad i did it, water although cold, felt warm in moments. Great scenery, camera will not do the trek justice. Get out there and do it. Amazing. Thanks Julio, sorry if I have spelt you name wrong.
