Długi Gronik (569 m a.s.l.) is a forested hill in the Pieniny range, marking the northeasternmost tip of the Pieniny Minor — right where the Dunajec River sweeps through a dramatic bend. It sits just outside the Pieniny National Park, which means free access and a quieter, more off-the-beaten-path feel than its more famous neighbours.

The northwestern slope opens up into a scenic terrace of meadows and fields known as 'Do Natonia', offering lovely views of Szczawnica, Dzwonkówka, and the western part of the Małe Pieniny range with peaks Palenica, Szafranówka, and Bystrzyk. On the southeastern side, at around 440 m, lies a flat clearing called 'Za Piecem' — this is where visitors arriving by traditional wooden raft from Szczawnica across the Dunajec (from the 'Nowy Przewóz' ferry landing) step ashore. The hill belongs administratively to the town of Krościenko nad Dunajcem, and its lower slopes are dotted with the small residential districts of Do Jurka, Do Grzegorza, and Do Kurpasa.

• Krościenko nad Dunajcem — green trail through the 'Do Natonia' terrace towards Przełęcz Sosnów pass, difficulty: easy
• From the upper slopes, continue on the blue trail via the 'Sosnów' glade to the peak of Sokolica — from this glade Długi Gronik is clearly visible

• The hill lies outside the Pieniny National Park — no entry fee required
• The 'Za Piecem' clearing is a landing point for rafters arriving from Szczawnica — combining a Dunajec raft trip with a hike here is a popular option

In 2016, two rare protected moss species were discovered here: Anomodon attenuatus and Ctenidium molluscum. Back in 1992, the rare fungus Clavaria fumosa was also found on this modest little hill — proof that small summits can hold big natural surprises.
