Rain can make footing slippery or muddy, swell streams and create more difficult crossings.
How we assess our guided hikes
The same distance can be a very different hike.
Hiking trail ratings are not consistent across destinations or organizations. A hike can be straightforward underfoot yet physically demanding because of its pack weight and elevation gain. Another may be shorter but involve difficult footing, ladders, tides or changeable weather.
Coastal Bliss Adventures uses a descriptive system for our guided hiking trips. It separates technical trail difficulty, physical strenuousness, and environmental factors. It is a planning aid, not a guarantee of conditions or a substitute for the itinerary and preparation requirements of a particular departure.

Three parts, one code

Illustrative example only; not an assigned rating for a specific trip.
CETechnical difficultyC usually; E at the hardest section
38StrenuousnessLevel 3 on most days; level 8 on the hardest day
adeEnvironmental factorsRain, fog, tides and ocean swell
In both paired ratings, the first character is predominant and the second is the maximum encountered. They do not indicate the first and second day of a trip, and they are not averages.
Part 1 · Two capital letters
Technical trail difficulty: A–G
Technical difficulty describes the nature of the route: how clear the trail is, the quality of the footing, the frequency of obstacles and the amount of route-finding required. The first letter describes the predominant trail conditions; the second describes the most difficult section.
For example, BD means that the trail is generally level B but contains sections that reach level D. When conditions are essentially the same throughout, the same letter can appear twice, such as CC.
| Rating | Trail conditions |
|---|---|
| A | Groomed trail with few obstacles or uneven sections. |
| B | Well-worn but ungroomed trail; some obstacles or uneven footing. |
| C | Identifiable trail; some route-finding may be needed. Uneven footing and occasional roots, rocks or other obstacles. |
| D | Identifiable trail; some route-finding may be needed. Uneven footing and regular obstacles. |
| E | Identifiable trail; some route-finding may be needed. Very uneven footing with many obstacles to negotiate. |
| F | Off-trail route-finding required; generally simple, open terrain with few obstacles. |
| G | Off-trail route-finding required; complex terrain with significant obstacles. |
The F and G categories describe off-trail route-finding. These ratings are designed for hiking journeys, not to replace specialized climbing or scrambling grades.
Part 2 · Two digits
Physical strenuousness: 1–9
Strenuousness considers the backpack weight carried, elevation gain and loss, and additional physical demands such as ladders or rope-assisted passages. It is a description of the demands of a guided hiking trip, not a simple ranking of distances.
How the two digits work
First digit: predominant level of strenuousness through the trip.
Second digit: highest strenuousness level reached on any individual day.
33Most days are level 3; no day exceeds level 3.
38Most days are level 3; at least one day reaches level 8.
77Most days are level 7; no day exceeds level 7.
We now always display two digits. On our updated pages, older single-digit codes have been converted by repeating the original digit. This is a formatting conversion, not a new assessment of the most demanding day. Read each trip’s preparation information and contact us if you have questions about the conditions.
| Rating | Physical demands |
|---|---|
| 1 | Day hiking with minimal carried weight; may still involve elevation changes or obstacles. |
| 2 | Moderate backpack weight, little elevation change, and no significant additional obstacles. |
| 3 | Moderate backpack weight, little elevation change, but significant additional demands such as rope pulls or ladders. |
| 4 | Moderate backpack weight and significant elevation change, with limited additional obstacles. |
| 5 | Heavy backpack weight, little elevation change, and limited additional obstacles. |
| 6 | Heavy backpack weight, little elevation change, and significant additional demands such as rope pulls or ladders. |
| 7 | Heavy backpack weight and significant elevation change, with few additional obstacles. |
| 8 | Moderate backpack weight with significant elevation change and/or significant additional demands such as rope pulls or ladders. |
| 9 | Heavy backpack weight with significant elevation change and/or significant additional demands such as rope pulls or ladders. |
These levels describe different combinations of pack weight, elevation change and obstacles. Higher numbers are not necessarily produced by adding or averaging lower-numbered factors.
Part 3 · Lowercase letters
Environmental factors: a–g
Lowercase letters identify conditions that can materially affect the route, effort, or travel decisions. A trip may carry more than one of these letters. Their presence means that the factor is relevant to trip preparation; it does not predict the weather on any particular departure.
b
Snow
Snow and cold can obscure the route, affect footing and increase the effort of travel.
c
Lightning
Exposed terrain may increase lightning risk during storms.
d
Fog
Fog can reduce visibility and complicate navigation; dampness can also affect footing.
e
Tides and ocean swell
Tides may affect route choice or access; swell can create hazards along shorelines.
f
Wind
Wind can make travel difficult and increase cold exposure.
g
Sun
Extended sun exposure on open ridges or shorelines can increase physical demands and heat stress.

Our overall trip descriptions
Alongside the full code, we provide a broader description. These labels help with an initial comparison, but they cannot replace the detail of the rating or the trip-specific preparation guidance.
| Description | General meaning |
|---|---|
| Light Moderate | Somewhat strenuous, but mostly simple hiking. |
| Moderate | Some sections may be strenuous for short periods, with some more complicated sections. |
| Moderately Strenuous | Elevation changes on some sections and/or more technical footing. |
| Strenuous | Significant elevation changes and/or technical sections and/or heavier pack weights. |
| Very Strenuous | Consistent elevation changes, heavier pack weights and/or technical sections. |

How ratings appear on our trips
These are examples from our individual trip pages. The code describes distinct aspects of trail conditions and effort; the overall label offers a shorter general description.
| Hiking trip | Trail code | Overall description |
|---|---|---|
| West Coast Trail | DE88ade | Strenuous |
| Juan de Fuca Trail | CE34ade | Moderately Strenuous |
| Nootka Island Trail | DF23adefg | Moderate |
| Cape Scott Explorer | BB22ad | Moderate |
Some shorter or basecamp itineraries may have a descriptive difficulty range without a complete alphanumeric code. That does not mean the terrain is without challenges. The relevant trip page and preparation information take priority.
Choosing a trip
Look beyond the overall rating.
Pay particular attention to the maximum technical and strenuousness ratings. The hardest section or day may be the one you most need to prepare for. Consider your comfort with backpack weight, repeated hiking days, uneven footing, elevation and weather exposure.
For basecamp trips, day-hike demands and the absence of a full overnight pack can make the experience substantially different from a backpacking expedition. Always read the individual trip page and preparation materials alongside its code.
