Moderate

More active trips that may involving hiking over moderate terrain, usually — but not always — with vehicle support and at elevations less than 10,000 feet, or trips with long overland travel, multiple sea kayaking days, wilderness camping, or other invigorating activity. On many trips, you can elect to skip a day’s activity, depending on logistics

Strenuous

Hiking over steeper or more rugged terrain or where elevations exceed 10,000 feet. Also includes river rafting trips with more challenging Class IV/V rapids.

Ultimate Challenge!

Our most demanding trips: trekking over steep, rugged terrain at high elevations (no vehicle support) or with substantial altitude gains and losses; trips to remote, extreme wilderness; mountaineering trips.

Note — Many people ask us about the difference between "hiking" and trekking.” Sometimes it’s a fine distinction, but we generally use the word "trek" to denote a long-distance hike in a remote area without access to roads; accommodations are usually in camps.
