Is altitude an issue on raft trips?
By definition, rivers are located at lower elevation than the highest areas of Colorado. Our rivers are located between 5,000 and 8,000 feet. Altitude causes shortness of breath and dehydration. Most people do not have serious problems here, but try to arrive a day or more early to acclimatize yourself if you can, and drink plenty of fluids while you are here. A headache often means you are dehydrated, drink a big glass of water.
