Bollards blocking access to motorized vehicles on the Kettle Valley Rail Trail in Naramata were vandalized on the weekend.
According to Justin Shuttleworth, the RDOS parks and facilities coordinator, there have been smaller acts of vandalism before at the Smethurst parking lot and Little Tunnel, but this was worse.
"This seems to be a pretty thorough effort to destroy the infrastructure," he said. "And they targeted more locations over the weekend."
The RDOS had expected some issues to come up when the motorized access was blocked at some locations on the trail.
Still, he said, this is unfortunate to see.
"We knew not everyone was happy, but we did our best to accommodate all users," he said.
With the vandalism appearing to escalate, the RDOS is in the midst of determining what to do next.
Current plans include replacing the bollards and other infrastructure and looking at an increased enforcement presence and other monitoring mechanisms.
The blockage is at intersections along the trail from about 400 metres north of Little Tunnel to the Penticton city limits.
People still wanting to drive to the Little Tunnel either in their cars or off road vehicles can do so from the Glenfir parking lot. They are able to get within 400 metres of the tunnel.
The compromise was reached between different user groups, the province and the RDOS in February, after many in the Naramata community expressed concern about the loss of vehicle access.
A group titled Keep Our KVR Accessible To All, KOKATA, was formed, to provide information on the situation.
