Po turistické trase se dá jít pěšky podle turistických značek.

Literally, po turistické trase means along the tourist trail / on the hiking route.

The preposition po often means along, around, after, or on, depending on context. In this sentence, it means along or via a route.

After po, Czech normally uses the locative case, so:

• turistická trasa = tourist trail / hiking route
• po turistické trase = along the tourist trail

That is why trasa changes to trase, and the adjective also changes:

• turistická → turistické
• trasa → trase

So the whole phrase is in the locative singular.

Dá se jít or se dá jít is a very common Czech way to say:

• it is possible to go
• you can go
• one can walk

It comes from the verb dát se, which in this kind of impersonal construction means to be possible.

So:

• dá se jít = it is possible to go / you can go

In this sentence:

• Po turistické trase se dá jít pěšky...
• You can walk along the hiking trail...

This is less direct and more impersonal than saying můžete jít (you can go). It sounds like a general statement about what is possible on that route.

Here, se is part of the impersonal structure dá se + infinitive.

It does not mean oneself here. Instead, it helps create a general meaning like:

• it can be done
• one can...
• it is possible to...

Examples:

• Dá se tam dojet autem. = You can get there by car.
• Dá se tu parkovat. = It is possible to park here.
• Po turistické trase se dá jít pěšky. = You can walk along the hiking trail.

So se is part of a common Czech pattern for making neutral, impersonal statements.

Yes, that is a very natural question.

Jít usually does mean to go on foot / to walk, so adding pěšky may seem redundant. But in real Czech, this is normal and often used for clarity or emphasis.

• jít = go, walk
• jít pěšky = go on foot, walk

Why add pěšky?

1. To make the mode of travel explicit
   It clearly contrasts with going by bike, car, bus, etc.

2. Because Czech often uses this combination naturally
   Even if the idea is partly already present in jít, jít pěšky is idiomatic.

So the sentence emphasizes that this route can be done on foot.

The preposition podle takes the genitive case.

So:

• turistické značky = tourist signs / trail markers
• podle turistických značek = according to the tourist signs / following the trail markers

Formally:

• singular: turistická značka
• genitive plural: turistických značek

This phrase means that you follow the trail by using the marked signs.

In Czech, turistické značky usually refers to the colored hiking trail markers used on trees, rocks, posts, and signs in the countryside.

So this phrase is better understood as:

• trail markers
• hiking markers
• tourist route markings

rather than just generic tourist signs.

That makes the whole sentence sound more natural in English as something like:

• You can walk along the hiking trail by following the trail markers.

Czech word order is flexible, and this sentence is arranged in a natural information flow.

Starting with Po turistické trase puts the route first, as the topic:

• As for the hiking trail, you can walk along it...

Then comes the impersonal possibility structure:

• se dá jít

Then the manner:

• pěšky

Then the additional detail:

• podle turistických značek

Other word orders are possible, for example:

• Po turistické trase se dá jít podle turistických značek pěšky.
• Podle turistických značek se dá po turistické trase jít pěšky.

But the original version sounds natural and clear.

Yes, similar ideas are possible, but the tone changes a little.

1. Po turistické trase se může jít pěšky...
   This is understandable, but slightly less idiomatic here than dá se jít.

2. Po turistické trase lze jít pěšky...
   This is more formal or written.

3. Po turistické trase se dá jít pěšky...
   This sounds very natural for a general practical statement.

So dá se jít is a very good everyday choice.

They are similar, but not always identical.

• turistická trasa = tourist route / hiking route
  This is a general route, possibly marked and described as a whole.

• turistická stezka = hiking path / trail
  This can sound a bit more like the physical trail itself.

In many contexts they overlap, and both can be translated as hiking trail. In this sentence, turistická trasa suggests an established marked route.

A very natural translation would be:

• You can walk along the hiking trail by following the trail markers.

Other possible translations:

• The hiking route can be walked on foot following the tourist markers.
• It is possible to go along the hiking route on foot, following the trail signs.

The first version is probably the most idiomatic in everyday English.
