Anyone concerned with exposed conditions
(e.g., narrow ledges or ridges and scrambling over exposed faces)
or uncertain of his/her strength
and stamina under the most demanding conditions SHOULD NOT attempt extra difficult hikes.

If the word exploratory appears in the comment section of the Hike Schedule,
it means that the hike listed may be a new one for CWH,
and/or the Hike Coordinator may not have explored the route before the scheduled day.
Be prepared for route finding, bushwhacking, and perhaps backtracking.

D1 - (C) CITY
More than 4 km and generally less than 10 km in length,
with minimal elevation gains, but may involve some climbing (e.g., Nose Hill Park).
This section includes city walks that are mostly considered easy.
Well-maintained trails, or walkways with few if any hazards to footing.
A relaxed pace with plenty of opportunities to stop for rests,
observe surroundings, and study the flora and fauna, or simply to socialize.
Prepare as you would for other hikes, bringing your lunch and adequate water.

D2 - (E) EASY
Generally less than 10 km in length with elevation gains of less than 300 M and no steep slopes.
Well-maintained trails with few if any hazards to footing.
A relaxed pace with plenty of opportunities to stop for rests,
observe surroundings, and study the flora and fauna, or simply to socialize.
Prepare as you would for other hikes, bringing your lunch and adequate water.

D3 - (M) MODERATE
Typically about 10-15 km in length and/or 300-500 M elevation gain.
May have the odd steep sections and rough trail conditions
(e.g., exposed roots, rocks or even occasional loose scree).
A steady pace is normally maintained with
fewer stops than on the easy hikes. Some endurance is required.

D4 - (D) DIFFICULT
Typically 15-25 km in length and/or 500-1000 M elevation gain.
You are most likely to encounter steep sections
as well as difficult footing (e.g., loose scree).
A brisk pace is required and
hikers must have both strength and endurance for the distance and the elevation.

D5 - (XD) EXTRA DIFFICULT
Either more than 25 km in length requiring superior stamina,
or in excess of 1000 M of elevation gain requiring strong legs, or both.
On the major climbs, very steep sections are almost certain to be encountered
with loose rocks and scree and other hazards
(e.g., scrambling over exposed faces or following narrow exposed ridges).
Unpredictable weather can greatly increase the hazards.
