Dutch flower gardens in summer

Nederlands Deutsch

In the summer, the Bollenstreek is best known for its beautiful beaches, dunes and the extensive Dutch lake district. From 1 August to 11 October 2026 the Dahlia Festival takes place and you can admire many summer flowers in the region. Dahlia show gardens in particular are becoming increasingly popular: in 2026 there are no fewer than five show gardens to visit. A must for young and old.

Dahlia show gardens

Due to the long flowering time of the summer flowers, there is plenty of time to admire the dahlias. From 1 August to 11 October 2026 the dahlia show gardens are in bloom and you can enjoy the wealth of colours of the versatile dahlia flower.

Below you will find the five dahlia show gardens of the Dahlia Festival 2026. All show gardens are located in the Bollenstreek and combine perfectly with a visit to the beach, the dunes or the Dutch lake district. They are all connected by the Bollenstreek flower cycle route.

Dahlia gardens at Keukenhof Castle

Keukenhof’s castle gardens are even more beautiful during the dahlia season because of the various dahlia show gardens that have been laid out there. In 2026 the dahlia gardens are extra large, so you can enjoy the summer flowers even more with Keukenhof Castle in the background. A walk on the estate is therefore extra special from 1 August to 1 October 2026.
