The station has two entrances and exits.
The main station entrance and ventilation building consists of four escalators and an elevator on the west side of Hudson Boulevard between 33rd and 34th Streets.
The main entrance has a turtle shell-shaped glass canopy above it that allows light to shine on the upper mezzanine.
The elevator is located south of 34th Street in Hudson Park, while the escalator entrance is located further east, closer to the boulevard.
At the time of construction, the ventilation building was designed so developers could build on top of it later.
The 55 Hudson Yards skyscraper, whose structure is partially atop the ventilation tower, started construction in January 2015, and pictures in May 2016 showed that the skyscraper had so far been constructed to the height of the ventilation tower.

The secondary entrance consists of escalators on the southwest corner of Hudson Boulevard East  and 35th Street, and opened on Labor Day 2018.
At both of the exits, the staircases and four escalators each go down 40 feet (12 m) to a fare control area, then another 80 feet (24 m) to the common lower mezzanine.

Both entrances feature the glass canopy design, the first of their kind in the subway system.
They are intended to stand out aesthetically.
The entrances are interweaved with the Hudson Yards developments, with the main entrance wedged between 50 Hudson Yards to the east and 55 Hudson Yards to the west.
The rest of the Hudson Yards development is located very close to the south of the station.
Both entrances are based on a design by architect Toshiko Mori, which itself is based on the design of smaller station entrances in the Paris Métro.

In the preliminary plans, there was to be an entrance inside the 3 Hudson Boulevard building, near where the secondary station building is located.
However, as both entrances were to use a glass canopy cover independent of any Hudson Yards structures, the 3 Hudson Boulevard entrance was shelved in lieu of a subway entrance directly to the east of 3 Hudson Boulevard.
Another plan called for an entrance at the southwest corner of Eleventh Avenue and 36th Street to serve the Javits Center directly.
Under this plan, the secondary exit would have been relocated to the north side of 34th Street west of Hudson Boulevard.
