The grade is an estimate from distance, climb, steepness, highest point and difficulty tags in OpenStreetMap. It is this app’s own rule, not an official grade.

Danger overview

Tap a layer for the detail, the source and the date.

These tiles are not a safety assessment. Tap one for coverage, source and date. The official bulletins come first.

Use at your own risk

Information only. Conditions change, the data can be wrong, and you are responsible for your own safety. Check the official bulletins on the day, tell someone your route and call 112 in an emergency.

The estimate adds distance in km, climb in metres divided by 100, and extra for steep, high or demanding routes. Under 9 is easy, under 18 moderate, 18 or more hard. It is our own rule, not an official grade.

Route quality signals

  • Waymarking is recorded in OpenStreetMap
  • Regional route (PR)
  • Route number PRC-BU 179
  • The route has its own website in OpenStreetMap
  • The route line has no gaps

These are facts recorded in OpenStreetMap. We show no stars and no reviews.

Danger layers

Each layer names its source and date. Where we have no credible source it says not covered.

Flooding

From map data

The national flood map puts about 0.7 km of this route inside the 100 year flood zone, and about 0.5 km inside the frequent 10 year zone. After heavy rain these stretches can be under water or impassable. Mapped zones do not predict flash floods in narrow valleys, so read the weather warnings before you go.

Wildfire

Live layer

Wildfire danger changes every day, so it is shown as a live layer and not as a fixed value for the trail. Regional rules can close forest tracks or ban fires in summer. Ask the local authority if you are unsure.

Check the official bulletin

Extreme heat

Not covered

No weather station with a long record is close enough to this route, so we show no heat figure. Check the AEMET warnings, and remember that strong sun and thin air at height still cause heat illness.

Snow and avalanche

Rule of thumb

The highest point is 1,106 m. Expect snow on this route from about December to March, and ice on shaded paths just outside those months. We found no official avalanche bulletin for this area, so avalanche danger is not covered here. Steep gullies and slopes can still slide after heavy snow.

Snow months are a rule of thumb from the height of the route, not a snow report. Avalanche information is the official bulletin only, linked here.

River crossings

From map data

OpenStreetMap shows 7 places where the route crosses a mapped river or stream with no mapped bridge. Small streams are often unmapped, so the real number can be higher. After rain a crossing can be too high to wade.

Exposure and steep ground

Not covered

Most of this route carries no difficulty grade in OpenStreetMap, so we cannot say how exposed it is. Look at the map and the photos, and ask locally.

What to carry

  • Water: about 2.5 litres for 4 h 50 min, at 0.50 litres per hour
  • Warm layers, gloves and a rain jacket. It is much colder at height.
  • Microspikes if there is hard snow or ice on the path.
  • The GPX file or an offline map, because phone signal is not certain.

These are rules of thumb from the length, climb and height of the route. They are not a complete kit list.
