Each workshop has been assigned a rating from the least demanding, Level 1, to Level 6, so students can find an appropriate activity level. Ratings reflect a combination of intensity and duration as well as distance, terrain, environmental conditions, weather, etc. For the most enjoyable and rewarding experience, please use your best judgment to match activity ratings with your health, physical condition, and individual circumstances. The range of hours for each rating will vary from workshop to workshop, please discuss with our office staff to find the workshop most suitable for your interests and level of fitness. Many of our long workshops involve long days out in the field starting well before sunrise and in many cases continuing beyond the dinner hour. Bear in mind that these programs involve group activities so your level of preparedness and ability will have an impact on other participants. All activity levels assume you will be handling your own luggage, carrying your own camera equipment, tripods and water while in the field and are able to get in and out of the vans or buses without undue difficulty.
