Gödöllő  is a city in Pest County, Hungary, about 30km east of Budapest. It is often visited as a daytrip from Budapest, or as a stop off while travelling to Eastern Hungary. It is among the most popular destinations for Austrians visiting Hungary, largely due to the royal palace, former home of Emperor Franz Josef and Queen Elizabeth.
Budapest has two suburban rail systems: the HÉV operated by BKV (the transport company in Budapest), and regular személy trains operated by MÁV (the national rail operator). Both serve Gödöllő, but not the same parts. However, if coming from central Budapest MÁV is almost always the better option.
The Gödöllő HÉV originates at Örs Vezér tere in Budapest, the eastern terminus of the metro line 2. Be sure to take train H8 towards Gödöllő and not one towards Csömör or Cinkota. Gödöllő has four HÉV stops: Erzsébet park (right in between the Felső Park and the scenic Erzsébet park), Szabadság tér, (in the downtown and steps away from the royal palace and city museum), Palotakert (near the Palotakert housing development), and Gödöllő (connected to the MÁV station of the same name). Service pattern is 4 trains/h during peak hours and 2 trains/h at other times, and the trip from Örs Vezér tere takes 51 min. Tickets can be bought at Örs Vezér tere or from the inspector onboard, and the fare is 745 HUF (though if you have a Budapest period travelcard, this is reduced to 370 HUF).
MÁV suburban rail
Gödöllő is also served by MÁV suburban trains on the Budapest - Gödöllő - Hatvan line, which originates at Keleti pályaudvar (metro line 2) in Budapest. Service pattern is generally 2 trains/h Budapest - Gödöllő with 1 train/h running onwards to Hatvan. Gödöllő has three MÁV stops: Gödöllő-Állami telepek (near the Arboreteum and Beekeeping museum), Gödöllő (connected to the HÉV terminus, 7 min on foot to the palace and 9 min to downtown), and Máriabesnyő (outside the pilgrimage temple). The Hatvan trains will stop in all three, the Gödöllő trains only at Állami telepek and Gödöllő station. The ride takes 38 minutes and costs 745 HUF (though if you have a Budapest period travelcard, this is reduced to 370 HUF).
Buses leave from Budapest, Stadion bus station (get off metro line 2 at Stadionok) towards the center of Gödöllő. Service intervals vary from 20-30 minutes in peak hours to several hours. Journey time is 35 to 55 minutes depending on the route taken.
Gödöllő is accessible by the M3 motorway out of Budapest.
Most of the main sights are within walking distance of Szabadság tér. The HÉV can be used within Gödöllő, at a cost of 155 HUF a ticket. If travelling to Máriabesnyő suburban trains bound for Hatvan leave every hour from the main station. There is also a free bus that runs from the train station to downtown and then on to TESCO that runs roughly every hour. A complete local bus schedule can be found at Volánbusz's website .
Grassalkovich Kastély (Grassalkovich Palace) , located across the street from the Szabadság tér HÉV stop, the royal palace is Gödöllő's main attraction. Built in the 1740s, the baroque mansion was originally home to Count Anton Grassalkovich. With the creation of the Austro-Hungarian Empire, the palace was given to the Habsburgs as a gift and was often frequented by Queen Elizabeth, better known as Sisi. During communism the palace fell into ruin and has only recently been partially restored. Besides a tour of the royal apartments, there are also the Baroque theater and the royal chapel. Concerts are also frequently held here.
Gödöllői Városi Múzeum (Town Museum of Gödöllő) , is located on Szabadság tér, close to the HÉV station. The exhibit focuses primarily on the Gödöllő artists' colony from the early 1900s, and has several excellent examples of Hungarian Art Nouveau. There is also an ethnographic exhibit on Oceania, collected by Ferenc Ignácz, who worked at the university in Gödöllő. Another small room houses the private collection of Zoltán Mihály Csupor, a Catholic priest.
City Parks Gödöllő is considered a city of parks. The three main parks are all located around the palace: Alsó park (lower palace park), Felső park (upper palace park), and Erzsébet park, named after Queen Elizabeth.
Máriabesnyő Pilgrimage Temple  Máriabesnyő is mostly easily accessed by taking the train to the Máriabesnyő station. You'll be greeted by a large Székely-style Transylvanian gate from 1942 as you walk toward the temple. The temple was commissioned by Grassalkovich when workers found a statue of the Virgin Mary on the site in 1759. It is the only two-storied baroque temple in the country, and you can also see the smallest Virgin Mary statue in the country, a museum about the Virgin, the Grassalkovich crypt, and do wine-tasting in the monastery.
