Route 230 is the main Bonavista Peninsula Highway, commencing from Route 1 (the Trans Canada Highway) at Thorburn Lake, about 10-15 kilometres north of Clarenville and proceeding all the way to Bonavista at the end of the Peninsula.

The highway now heads northeast through rural areas to pass Morley's Siding and Lethbridge, where it has intersections with Route 233 (Clode Sound Road) and Route 234 (Winter Brook Road).

The highway heads through more rural terrain before entering the Trinity Bight area and beginning to follow the southern coastline of the peninsula at Lockston, where it also has an intersection with Route 239 (New Bonaventure Road).

Route 230 now heads north along the coast to pass through the town of Trinity Bay North, where it passes the communities of Melrose, Port Union, and Catalina, as well as where it meets Route 237 (Blackhead Bay Road).

The highway passes through more neighbourhoods before making a sharp left turn and coming to an end shortly thereafter at another intersection with Route 235 (Church Street).
