Some of you with early trips may be excited at the thought of seeing all those wildflowers in bloom but grimacing at the possibility of traveling in colder temperatures. Read about tips on packing for a cold weather trip.
You’ll still probably want a set of moisture-wicking underwear or a bathing suit closest to your skin, but on top of that, consider wearing something like wool long-johns or neoprene pants and a neoprene shirt. (NRS makes some great neoprene gear called “HydroSkin.”) Wool or neoprene are great materials because they continue to insulate and keep you warm even when wet. Just make sure you don’t wear anything that is a single piece as that will be hard to put on and take off throughout the day.
In April and September, you might be surprised at the cooler temperatures, especially mornings and evenings. Instead of the lightweight fleece on your gear checklist, opt to bring a mid-weight or heavy-weight style depending on your sensitivity to cold. If you would have packed a pair of cotton shorts to sleep in, exchange them for sweatpants instead. Also when packing for cold weather trips, simply having items that can be layer can help get the warmth you want without adding bulky items.
For summer trips, we typically recommend lightweight, waterproof rain gear. But, if you’re traveling at a colder time of year, you may want to bring waterproof rain gear with a little bit of insulation built in.
Beanies on cold-weather river trips can be small item with a big impacts on cold weather trips! So are gloves, neoprene or wool socks, and any other little items that will help you stay just a bit warmer. Those small things can be easy to add to your bag without sacrificing space.
You might not need half of what we recommend above, but you’ll be glad to have it if the temperature drops of it you are know to be sensitive to cold temperatures. Research the weather in the canyon a few days before your trip starts so you can be prepared, which can be found on our homepage. (Note: Search weather.gov for the weather at Phantom Ranch, and make sure the elevation is 2805 for an accurate forecast.)
Keep in mind that no matter the forecast outside, the water will likely be around 50 degrees.
You’ll still need to keep your gear under 25lbs or risk paying overage charges, but make sure to bring what you need. Even if you don’t use everything you bring, you’ll be happy you had it in case.
There are parts of the boat where you are a little less likely to get completely soaked. The tea room (the square area back near the guides) is a great place to sit if you run on the colder side or just need a break from the splashes.
We just want to make sure you have all the information you need to stay as comfortable as possible so that you can have the best vacation of your life!
