Pickup, door to door
From 09:00
We leave Amsterdam early and drive south. The flat polders slowly give way to the only real hills the Netherlands has.
Two hours south, a different Netherlands begins. For the ones who love the open road, and the places the day trips skip.
Almost no visitor leaves the flat, famous part of the country. They miss the south: real hills, one of the oldest cities in the Netherlands, and a maze of caves carved by hand under a mountain. This is a private road trip down to Limburg. A walk through Maastricht, an hour deep inside the marl caves of the Sint-Pietersberg with a specialist guide, free time for lunch, and the old castle town of Valkenburg. Twelve hours, door to door, just your group, in English or Greek.
Hills, a wide river, tunnels cut by hand over centuries. Real frames from a real day down south. No stock, no rush.
Twelve hours, one car, your group. The plan is real, the pace is yours.

We leave Amsterdam early and drive south. The flat polders slowly give way to the only real hills the Netherlands has.
About 1 hour
A walk through one of the oldest cities in the country: the grand Vrijthof square, the streets along the river Maas, and the layers of Roman, Spanish and Dutch history packed into one beautiful old centre.
About 1 hour
Up to thirty metres beneath the Sint-Pietersberg, a Maastricht Underground guide leads you through a maze of marl tunnels, around sixty kilometres of them, cut by hand over centuries. You see charcoal drawings and inscriptions left by the workers, the spaces that sheltered the city through sieges and wartime, and the vault where roughly eight hundred masterpieces, including Rembrandt's Night Watch, were hidden during the Second World War.
Free time
Then the day slows down. We stop for lunch, your choice and not included, so you eat what you actually feel like.
Free time
We finish in Valkenburg, a small town built into the hills, with a castle ruin above the rooftops and old streets below. Free time to wander before the drive home.
By 21:00
We bring you back to your door, with a short film of the whole day on its way to you.
This corner sits between Belgium and Germany, with hills, vineyards and a softer, older rhythm. Maastricht was a Roman river crossing long before the modern Netherlands existed, and you feel that age in the stone.
The caves are not natural. For centuries people cut marl, a soft limestone, out of the hill to build with, and left behind tens of kilometres of corridors. Walking them is walking through that labour.
During the Second World War the safest place for the country's greatest art was underground. In a sealed vault inside these caves, hundreds of paintings waited out the war, the Night Watch among them.
