Regional Cycling Routes (RCTs) in the Brussels-Capital Region

Routes
Regional Cycle Routes (RCTs) are recommended pathways for
medium- and long-distance cycling trips through several municipalities.
As a rule, these routes take local roads, where traffic
is less dense, less fast, and therefore less stressful than on roads
main ones. But the crossing of certain natural obstacles or
artificial (bridge crossing a valley, canal, highway, passageway
under a railway line, etc.) sometimes brings the routes back to the
main axes.
