Tisvildeleje is the coastal part of Tisvilde. "Leje" roughly translates as "plain" and used to be a fishermen's village. Now all of the fishermen's houses are used as "quintessential" summer residences. The southeast of Tisvilde is referred to as Tibirke.

Tisvilde, alongside Hornbæk further to the east, has the highest prices of summer houses in Denmark. A 175 sqn summer house was sold for DKK22 mio. in 2017.

The etymology of Tisvilde is not known for certain. As "Ti's vælde" it can be understood as “Where Tyr Reigns” (Ti is a common word for Tir (Týr) in Danish place names). "Væld" also means a spring, perhaps a reference to Helene Spring. "Væld" is similar to the old Norse word "ved" or "wald" meaning forest. Tisvilde was previously covered by extensive oak woods, before the sand drifts began.

The word Leje is used in several other place names in Denmark, such as Liseleje west of Tisvildeleje or Rågeleje and Gilleleje to the east.

From around 1500, drifting sands began to bury the fields and farms around Tisvilde. The problem accelerated over the years and by 1700, most of the area had been deserted. Several attempts to counter the forces of nature, had been tried, but in 1724 the German Johan Ulrich Røhl was hired by the Crown and by help of the local peasants and 100 soldiers from Copenhagen, they managed to stop the dunes in the course of the 1730s, by covering them with seaweed and digging trenches. But while the dunes was successfully stopped in their march against civilisation, the sands had covered and transformed the countryside and made it completely barren. From around 1800 to 1900 this state was reversed, by planting the c. 1,300 ha forest of Tisvilde Hegn in association with the plantations of Asserbo and Liseleje southwest. The first tree species to be planted was scots pine and later followed by spruce, birch, beech and oak. Tisvilde Hegn is the oldest plantation in Denmark and now a Natura 2000 area, due to its rare habitat-types, flora and fauna and important birdlife. This area is a part of the Kongernes Nordsjælland National Park. Some of the species protected here are northern crested newt and large white-faced darter.

The coastline at Tisvilde Hegn is known for its stretches of white, clean and child-friendly sandy beaches.

• Helene Spring is one of Denmark's most famous springs, and legend has it that anyone whose illness has not responded successfully to other forms of treatment must come to the spring on 23 June (Sankt Hans Eve or Midsummer's Eve). Culturally, legend in Denmark has it that if one consumes a certain amount of water from its springs in the night and then stays at Saint Helene's grave until morning, he should be cured of all his sicknesses.
