How to reach us

The Institute is located in village Ondřejov 30 km south-east of Prague city limits near the highway D1. It can be reached by car, by bus or you can take train and walk the rest. Ondřejov and the surrounding countryside is also a popular target for bicycle trips.

Fly to Prague Airport and arrange for someone to pick you up and drive you to the Institute. This is far the best option. A cab would cost you about 80 EUR. If you prefer public transport on your own, be prepared for another two hours of traveling. Take bus 119 outside the airport terminal, go to Nádraží Veleslavín and change for metro line A there. Continue by metro to Háje changing to line C at Muzeum and then use bus route 383 (goes about once an hour, check the timetable and bus instructions bellow).

Traveling by car, take exit 21 on D1 highway Praha–Brno (direction Benešov). Right after the highway exit take a turn, enter village Mirošovice and head for Mnichovice. Continue about 4 kilometres and turn right in Mnichovice towards Ondřejov, where at the beginning of the village (by a sawmill) you will see a sign pointing left to the Institute.

Ondřejov is served by two ROPID (Prague local transport authority) bus routes. Route 383 (timetable) goes from Prague and starts at Háje station (metro line C terminus). The ride takes approx. 60 minutes. Alternatively, you can take train to Strančice and change to bus route 490 there (25 min; timetable).

Trains from Prague mail railway station stop at Strančice from where you can take bus 490, or get off at Mirošovice or Senohraby and have a pleasant walk (5 km; follow turistic marking).

A number of marked walking trails connect Ondřejov with major neighbouring villages. Yellow trail that connects Mirošovice and Chocerady runs directly through the observatory.

Sorry, we are on a hill.
No direct connection from Hamburg is available.
