Løypekrysset ligger langt fra rasteplassen.

It is a compound noun:

• løype = a trail, route, or track, often a ski trail or marked path
• kryss = a crossing or intersection
• -et = the definite ending for a neuter noun

So løypekrysset literally means the trail intersection or the junction of trails.

Because Norwegian usually writes compound nouns as a single word.

So where English often uses two words, Norwegian often combines them:

• løype + kryss → løypekryss
• raste + plass → rasteplass

This is very important in Norwegian. Writing them separately often looks wrong or changes the meaning.

Those are definite endings, and they depend on the gender of the noun.

• et løypekryss → løypekrysset
  This noun is neuter
• en rasteplass → rasteplassen
  This noun is masculine

So both nouns are definite, meaning the trail intersection and the rest area.

In Norwegian, ligge is very commonly used when talking about where a place is located.

So:

• Løypekrysset ligger langt fra rasteplassen = The trail junction is located far from the rest area

Using er is not the natural choice here. Norwegian often uses verbs like:

• ligge = lie, be located
• stå = stand
• sitte = sit

These are often used where English would simply say is.

Langt fra means far from.

• langt = far
• fra = from

Together they form a very common expression for distance:

• langt fra byen = far from the city
• langt fra skolen = far from the school

So in this sentence, it says the trail junction is far from the rest area.

Here, langt is being used adverbially, not as an adjective directly describing a noun.

Compare:

• en lang vei = a long road
  Here lang describes the noun vei
• Det er langt til byen = It is far to the city
  Here langt describes distance more generally

In langt fra, langt is the normal form. It does not agree with løypekrysset here; it is just the standard adverb-like form in this expression.

Løype can mean a prepared or marked route, trail, or track. The exact English translation depends on context.

Common possibilities include:

• ski trail
• trail
• route
• track

So løypekrysset could suggest a junction where marked trails meet, especially in an outdoor or skiing context.

The word order is:

• Løypekrysset = subject
• ligger = verb
• langt fra rasteplassen = adverbial phrase of location/distance

So the structure is basically:

Subject + verb + distance/location phrase

That is a very normal Norwegian sentence pattern.

Yes. That would also be correct.

It means:

The rest area is far from the trail junction

The basic situation is the same, but the sentence focus changes. The first version starts with the trail junction as the topic; the second starts with the rest area.

Yes, they could be indefinite in other contexts, but the meaning would change.

Here, the definite forms suggest that both places are specific and known:

• løypekrysset = the trail junction
• rasteplassen = the rest area

If you used indefinite forms:

• et løypekryss
• en rasteplass

that would mean a trail junction and a rest area, which sounds less specific.

The letter ø is a Norwegian vowel that does not exist in standard English.

A rough approximation:

• It is somewhat like the vowel in French peur or German schön
• For English speakers, one way to approximate it is to say eh while rounding your lips more

In løype, the beginning sound is not like English low. It is a different vowel, followed by a glide.

You do not need a perfect English equivalent; it is better to listen and imitate native pronunciation.
