A road along the coast connected it to Skotterup and Snekkersten) to the north and Humlebæk, Sletten) to the south.
Espergærde, together with the villages Mørdrup and Tibberup, belonged to the mansion Krogerup situated to the south.
The farmers in these villages had to make hoveri (farm work) for the mansion, and the road from Mørdrup to the south towards Tibberup (and from here further on to Krogerup) still has the name "Hovvej", referring to these conditions.
Along the coast line, and in front of the slope south of Espergærde harbour, fisherman houses were built with easy access to the sea.
Kinck won the election in Helsingør on 8 January 1841 for the Provincial Represents Council for the Danish Islands over the conservative candidate.
A steam boat line was expanded to the north and from 1877 the steam boat made stops in Copenhagen and the villages along the coast: Skovshoved and Bellevue Beach, Tårbæk, Skodsborg, Vedbæk, Rungsted, Humlebæk, Snekkersten, Helsingør and Helsingborg.
The same year a post line opened from Elsinore to Snekkersten, Skotterup and Egebæksro (on the fringe of the forest Egebæksvang just south of the small Egebækken stream running into The Øresound).
The post coastline stopped after a short time but the summer holiday visitors continued to grow.
Until the 1870s the visitors came mainly on day trips to the forest and the beach, but according to the law of business enterprise (næringsloven) of 1857 it was specifically allowed that house owners could rent their homes to foreign visitors and supply them with food, so the local people started to rent out their homes during the summer and themselves lived in a building for stocking materials, horse staples or other secondary purposes.
More and more houses and summer cottages were built between the village and the railroad station on the southern side of Egebæksvang forest.
The development continued until World War II, and the fishermen's village became a true town, first with many summer holiday visitors, later as a residential area for people working in Elsinore or Copenhagen.
Espergaerde features in the song "Denmark, 1943" by American folksinger Fred Small about the rescue of the Danish Jews: And it's fire up the diesel and look out for swells / We're leaving Espergaerde behind us / Who strike at our friends strike us as well / We'll pray the patrol boats don't find us / When the sirens are wailing and shouts fill the night / Never will you stand alone / So it's over the Øresund / Till the day we can welcome you home.
In the north Mørdrupvej (vej = road), passes the villages of Gurre and Nygård and ends in Ålsgårde.
To the west the town is limited by the Rolighedsmoserne (a swamp area) and part of Kelleris Hegn (a forest) situated between Nordbanen (railroad) and Helsingørmotorvejen (Elsinore motorway).
