Do you have more time for trips within the Czech Republic? Great! We would love to introduce a perfect outdoor day trip from Prague to Velká + Malá Amerika Limestone Quarries. The Velká Amerika quarry is often referred to as the Czech Grand Canyon and probably from there comes the name America 🙂

This trip is perfect for all nature and history lovers because you can also visit Karlštejn Castle on the way.

About Quarries

Nestled just a stone’s throw away from the bustling heart of Prague lies a natural wonder that many travelers might overlook. The Velká Amerika quarry is the largest of the quarries, with the Mexiko and Malá Amerika quarries also being well-known. This area has been a sought-after destination for tramps for many years and is a popular place for family trips, ranking among the most beautiful places in the Czech Republic. Especially, the yellow trail leading to Karlštejn Castle is popular.

1) Velká Amerika (Great America) Quarry

The Velká Amerika quarry is the first quarry you will reach if you arrive by car or bus to Mořina. It is a massive limestone quarry measuring about 800 meters in length and 200 meters in width. The depth of the Amerika quarry is up to 100 meters. At its bottom, there is a lake with beautifully clear water.

Access to the viewpoints at the edge of the quarry is mainly from the yellow tourist trail. The quarry can also be walked around from its other side. The most beautiful view is from its southwest end.

2) Malá Amerika (Little America) Quarry

The Malá Amerika quarry is the second limestone quarry with crystal clear water. The lake at its bottom is called Rešenské, and the water in it is so clean that even protected crayfish live there. Swimming and entry are prohibited, just like in Velká Amerika. In the walls of the quarry, you can observe large square holes – these are the former mining tunnels. The main collecting corridor of the 3rd mining team leads here. Currently, the tunnels are an important wintering site for bats.

3) Mexiko Quarry – Former Political Prisoners’ Quarry

Tourists may know this quarry more by the name Mexiko. However, this quarry experienced the cruelties and inhumanities of the communist regime. Between 1949 and 1953, about 2,000 prisoners passed through it. Almost all ended up in a destitute state in the Pankrác hospital after a few weeks. Prisoners who survived this “Czech Mauthausen” pooled their resources and erected a memorial at this penal quarry.

How to get to Velká Amerika from Prague?

How to get to the Velká Amerika quarry? The Velká Amerika quarry is located just 21 km southwest of the center of Prague. You can easily get there by car, but also by public transport.

By Car

The quarries are located near the village of Mořina. For navigation, you can enter “Velká Amerika” directly. From the center of Prague, the fastest way is via the D5 motorway, which you leave at exit 10 – Loděnice. From there, drive through Kozolupy to the quarries. If you come from another direction, simply head uphill from the village of Mořina towards Kozolupy/Bubovice. When arriving from Mořina, you will have the quarry on your left side.


You can park without problems directly at the Velká Amerika quarry. There are two larger parking lots, and parking is free. The yellow tourist trail also starts from here, leading you to other quarries.

By Bus

You can easily reach Mořina by bus from Prague – Zličín, which stops in the village of Mořina. From the stop in Mořina, it’s a 1 km walk to the Amerika quarry following the yellow trail. Directly at the Velká Amerika quarry, bus no. 311 stops, which also departs from Prague – Zličín, but this line only stops here 1-3 times a day (stop Mořina, quarry branch). To find the best connection, we recommend IDOS.

By Train

The nearest railway station is Karlštejn. Trains on the route Prague – Karlštejn – Beroun run at regular half-hour intervals. You can download the train schedule in the app Můj vlak.

Trip TIP:

Between Karlštejn and the Amerika quarries, there’s a beautiful tourist trail. If you want to take a nice trip, we recommend arriving by bus to Mořina and starting the trip from Velká Amerika because buses don’t run as frequently as trains. If you choose the opposite approach, starting at Karlštejn, you might have to wait up to 2 hours in Mořina for a bus.

Visiting Querry Tunnels

Around the Velká Amerika Quarry, there are beautiful viewpoints where you can take stunning photos. Direct access to the quarry is prohibited, making it challenging to get down there. The quarries are owned by the company Lomy Mořina spol. s.r.o., and if you violate the ban, you can be fined 15,000 CZK (650 USD). So, there’s no entrance fee or opening hours. The ban on entry is primarily for safety reasons.

However, if you still want to see the underground tunnels of the Velká Amerika quarry, there are two options:

a) Pre-arranged tunnel tours with the Hagen Association (OS Hagen)

Private tours and excursions into the underground tunnels are possible for groups of 10 or more, or by agreement. For more information, check out the association’s Facebook page or contact them directly at [email protected].

b) Annual “European Day of Protected Areas” event

This event takes place just once a year, offering an educational trail, excursions, and passage through the tunnel from Dub Sedmi bratří to the Malá Amerika quarry. For current event details, follow the websites of the Protected Landscape Area of the Czech Karst (CHKO Český Kras).

Swimming in the Malá and Velká Amerika Quarries Swimming in the quarries is also prohibited. Violating this ban can result in a fine of 15,000 CZK (650 USD). Unfortunately, swimming cannot be arranged with the Hagen Association either.
