7 trip ideas in Slovakia’s Trenčín region, plus a cave with a secret lake

To me, the Trenčín region is much more than the town of Trenčín, and you need several days to explore it. My picks are Bojnice Castle, Trenčín Castle, the Čajka v oblakoch lookout tower, the Haluzice church and gorge, and the Hladový prameň cave. For something extra, try a flight in a light aircraft from Prievidza.

I wrote this article in 2019. Prices, opening hours and connections may have changed since then, so check them before you travel.

In this article you’ll find trip ideas for the Trenčín region that I tried out over the past few days. I had naively assumed the Trenčín region was just the town of Trenčín and the villages around it.

Day trips in the Trenčín region

But then I found out that the Trenčín region covers more than 4,500 square kilometres, and it dawned on me that there had to be more to it. Here’s where to go on day trips in the Trenčín region.

Tip from Milan I’d recommend booking your accommodation as early as you can, because rooms in a good location at a fair price go first. Here you’ll find accommodation offers in the area valid today.

Scenic flights at the Prievidza aero club: what they cost

If you’ve never been on a scenic flight in a small plane, I recommend a visit to the aero club in Prievidza. When I was there in 2019, a minute in the air cost €3. It’s best to check the current price with the club directly. Introductory flights run at weekends from April to the end of September, weather permitting. I’d tried a similar flight around Zvolen Castle a while back, so I was really looking forward to this one. If you’ve never had a private pilot of your own, it’s well worth it: he’ll fly wherever you ask and give you a lovely tour of the whole Trenčín region from above.

The pilot told me how, a few years ago, some grandchildren clubbed together to give their grandmother a scenic flight at the Prievidza aero club. They flew with her over her house and were amazed at how well she found her bearings in the air and knew the name of every village. The grandchildren, meanwhile, looked down at Prievidza and the countryside around it and had no idea where they were. Priceless.

Scenic flights at Prievidza airfield: prices and glider building

At the aero club they also build aircraft (mostly gliders) to order. There are three production halls here, where Slovaks build gliders from fibreglass laminate and resin. Building one aircraft takes about four months. Every glider has to be painted white, because black laminate goes soft. If a glider starts to turn yellow, it has to go in for servicing, since the maximum operating temperature of the laminate is 50°C, and only pure white laminate stays that cool.

Here’s how to book a scenic flight at the Prievidza aero club: phone +421911110504 or email info@aeroklub-prievidza.sk. A flight makes a great present, because flying in a small plane is quite an experience. In 2010 the airfield also hosted the World Gliding Championships. It fits nicely alongside your other trips in the Trenčín region.

Čajka v oblakoch: a barrier-free lookout tower in Bojnice

Čajka v oblakoch (‘Seagull in the Clouds’) is a lookout tower in Bojnice near Prievidza, and it’s barrier-free too. I’ve recently started paying more attention to accessible travel, because I believe everyone should be able to travel. The tower stands in a great spot on a hill above Prievidza, with views of the airfield, the town and the surrounding villages. And if you don’t feel like walking back down, you can take the slide.

Čajka v oblakoch: tickets, height, parking and the slide

• Čajka v oblakoch is 30 metres tall.
• Ticket prices vary. In 2019 adults paid €8, children €4 and babies under three went free, and a ride on the slide cost €1. Since February 2026 a ticket to the tower has cost €12 and a ride on the slide €2.50. The slide is usually open only at weekends and on public holidays, when the weather is good. You’ll find the current price list on the tower’s website.
• Opening hours change with the season, so check them on the tower’s website before you go.
• There’s a car park a short walk from the tower, with plenty of spaces.

Bojnice Castle tour: the clock collection and the magic mirror

I’ve never been one for those classic castle tours where a guide leads you from room to room and talks about the carpets. Still, on the Bojnice Castle tour I picked up a few really interesting facts, or rather titbits, since I only touch on history on this blog.

The castle has a collection of rare clocks, such as a longcase clock made by a Bavarian master who worked in Upper Hungary, in what is now Banská Bystrica. Here’s my guide to what to see in Banská Bystrica. What caught my eye more was an unusual clock with no hands. You could spend ages looking for the movement, because it sits in the crown of a statue. From there it drives the dial, and the only hand is the sceptre the statue holds. The sceptre shows the time as the crown turns to the current hour. The clock also has a small bell that used to strike the hours.

The castle also has a mirror: smile into it and you’ll wake up younger the next morning. I tried it. Do you think it worked? As you leave, look out for the bullet marks on the outside of Bojnice Castle. They were left by the Hlinka Guard, the militia of the wartime Slovak State, as it passed by. And on the tour, don’t skip the cave beneath the castle.

Bojnice Castle: a few curiosities

Trenčín Castle: the view from the tower and a Roman inscription from 179

Trenčín Castle dominates the whole town of Trenčín. The first written record of the castle dates from the 11th century, but it has changed a lot over the centuries. Its best-known owner was Matúš Čák Trenčiansky, who owned another 50 castles on top of this one. Not bad going. He died right here at Trenčín Castle at the age of 60, but his grave has never been found. Perhaps it’s still hidden somewhere in the castle, even though the whole castle was gutted by fire in 1790.

The fire broke out down in the town and spread all the way up the hill, and the castle was very nearly lost. Today it’s a National Cultural Monument, and restoration work is still going on. I also recommend stopping at the Hotel Elizabeth below the castle, where you can see the Roman inscription on the castle rock. Dating from 179, it’s the most important ancient inscription in Slovakia and celebrates the emperors’ victory at Laugaricio, the Roman name for Trenčín.

A trip to the Haluzice church and gorge

The village of Haluzice lies close to Nové Mesto nad Váhom, and besides the well-known Haluzice gorge (Haluzická tiesňava), it also has a pretty church, which I only discovered a few years ago. The gorge is considered a Slovak primeval forest, and remarkably, it is still getting deeper. Above the gorge stands the 13th-century Haluzice church.

What makes it unusual is that it has its own fortifications, something you rarely see today. So the church served both as a refuge from enemies and as a place for local markets. Today you can simply wander round it and combine it with a walk in the gorge.

Visiting the Hladový prameň cave

I’ve never been a fan of caving, and I don’t much like dark, enclosed spaces I might never get out of. One of my stops in the Trenčín region was the Hladový prameň cave, but I only enjoyed the tour as far as the halfway point, where I turned round and went back out.

Hladový prameň (‘Hungry Spring’) is the name of the river that rises in the cave. It’s the only cave in the Čachtice Karst with an active watercourse, and its rhythm is interesting too: the cave regularly floods and dries out again. This creates an intermittent stream and underground lakes, which you can only reach with a guide. The water level depends mainly on the groundwater and is very irregular. Locals have also started calling it the Občasná vyvieračka (‘Intermittent Spring’). At the bottom there’s a lake, and most of our group went down to see it.

Between 1988 and 1991 the water in the cave dropped to the very bottom, which is extremely rare. Its depth is about 6 metres, and when the cave fills up, the water flows out and floods it right up to the ceiling. It’s quite possible that Hladový prameň connects all the way to the Čachtice Cave (Čachtická jaskyňa).

You can visit the Hladový prameň cave too, but you have to arrange it with the people who hold the keys and will take you in. Going in alone isn’t allowed, because it can be dangerous. Our visit was arranged by the team at KOCR Trenčín, the Trenčín regional tourism board, and you’ll find their contact details here. Bear in mind that Hladový prameň is very narrow, which is why I decided to go only halfway.

Čachtice Castle and the legends of the Blood Countess

Every Slovak knows Čachtice Castle: it’s one of the country’s icons. I won’t retell the legends of the Blood Countess, the Lady of Čachtice, here, because we all know them. What I bet you don’t know, though, is that Elizabeth Báthory also experimented with spells and witchcraft.

Trips in the Trenčín region: where to go and what to see

The Trenčín region is exhausting: there’s so much to see and visit. I’ll definitely be back to discover the other stories, castles and ruins in the area. *This article was written in collaboration with KOCR Trenčín.
