a visitor center, the Lainzer Tor is the preserve's main gate. It is also the origin and the terminus of a walk to the Hermesvilla, which can often also be ridden via horse carriage. Public restrooms are also located near the gate, as is a water fountain. This is also one of two gates that has a parking lot. The Lainzer Tor is located at the end of Hermesstraße, and is reachable using the 56B bus, which connects the gate to the 60 and 62 trams line and to the U4 U-Bahn line (Hietzing station) at 15- to 20-minute intervals. These tram lines can be taken from the stop Speising, Hermesstraße, and connect to multiple U-Bahn and S-Bahn lines. Line 62 can also be taken directly from the Vienna Staatsoper to Hermesstraße. Gütenbachtor The Gütenbachtor is located on Gütenbachstraße, and accesses the southeastern corner of the Lainzer Tiergarten. It also features a water fountain and a parking lot, but is a 45-minute walk from the nearest public transportation, regional bus lines 253 and 254. Laaber Tor The Laaber Tor is located by the Lower Austrian town of Laab im Walde. It accesses a separate corner of the Lainzer Tiergarten that was added in the 1960s as a compensation for territory that was lost in the north of the preserve when a highway was built. Visitors using this gate will pass the Dianator, which was the gate in this corner before the annexation of additional land. The Laaber Tor also has a water fountain. Similar to the Gütenbachtor, the only public transportation within reach is the regional bus line 253, which is a 15-minute walk from this gate. Pulverstampftor The Pulverstampftor is located in the northwest corner of the preserve, near the Auhof neighborhood of Vienna's 14th district. It features a water fountain, and can be accessed from the Umspannwerk Auhof stop of the bus line 50B from Hütteldorf (five-minute walk). Nikolaitor Due to its location near the Hütteldorf railway station, the Nikolaitor is an important gate of the Lainzer Tiergarten. Hütteldorf can be accessed with the U-Bahn U4, S-Bahn S45, S50 and S80, tram line 49, as well as multiple bus lines. From the station it is a 10-minute walk across the Wien River to Nikolaigasse. This gate also features a water fountain. Adolfstor The Adolfstor was located along the eastern wall of the Lainzer Tiergarten. It is now closed.
