Looking for beaver signs in autumn: watch the branches, not a boat timetable
Beavers are mostly active at dusk. In October, gnawed branches and lodges are more realistic goals than seeing the animal itself.
The beaver has returned to the Netherlands. Natuurmonumenten says the species was reintroduced from 1988, first in the Biesbosch and later in other areas. Beavers now live in every Dutch province. Spotting one remains difficult: they are chiefly active at dusk and at night.
Along the water, signs are easier to find. Natuurmonumenten points to lodges made from piled branches, gnaw marks and smooth tracks leading into the water. Fresh branches stripped of bark stand out in a pale colour. Research institute Zodion describes winter, from December through February or March, as the best time to survey banks for lodges and other traces. More vegetation remains in October.
On Tiengemeten, a marked beaver trail passes places where lodges can be found. The organisation warns that the chance of seeing a beaver is small. In Harderbos, a short blue route of about four kilometres starts at Karekietweg. Dogs have not been allowed there since March 2024, and paths can be muddy in autumn.
The Biesbosch MuseumEiland’s beaver boat trips run from May through September, according to the organiser, so there is no such trip on Monday 19 October. If you walk now, keep your distance from lodges and animals. The land managers publish current information about access, routes and ferry services.
