Hi @florence.henry,
the roads leading to those locations are tagged with access:private
. Ors won’t include these roads in the graph used for route computation.
and https://www.openstreetmap.org/way/136114854#map=12/-29.1767/-70.8268
you could use this workaround Add possibility to turn acccess restrictions off when calculating a route
although travel time won’t be correct.
There is currently no way to route on private roads with ors.
best regards
