For most trips, booking 1 year in advance gives you plenty of time.
If you have a smaller group and aren’t picky about dates, you can often find a trip that will suit you during the same calendar year that you would like to travel.
If you have a large group or you have a very narrow window of dates that will work, you may want to get in touch with us a year to a year and a half in advance. Oar-powered trips, Upper and Lower Canyon trips, and Hiking Focused trips have much more limited offerings and also tend to book up sooner than 1 year in advance.
