By public transit
Tram line 19 goes from Sloterdijk via Leidseplein, Weesperplein to Diemen. It is a 30 minute ride from Leidseplein. If you are coming from the Central Station the best way is to take the metroto Weesperplein and from there on take the tram to Diemen, as there is no longer a direct tram line from Central station to Diemen.
As Amsterdam is the bike capital of the world, the best way to explore Amsterdam and its suburbs is by bike. It is approximately 7 km to Diemen from Dam square. That might be a long ride but you also see parts of the Plantage and Oost neighbourhoods.
- 1 Diemerbos, Main entrance at Muiderstraatweg (Tram 19 to the final stop in Diemen Sniep, from there 20 min walk to entrance of Diemerbos. Or buses to Stammerkamp and a short walk to the entrance). Large forest at the end of Diemen with several marked walking routes. A lot of the paths are rural and can be wet. Quieter and more raw nature than Amsterdamse Bos.
- 2 Diemer Vijfhoek. Large artificial island with a lot of raw nature on it. Nice place to walk
