I'm trying to book travel from Sokcho-si to Gyeongju, which Rome2Rio suggests taking as a bus trip from Sokcho Express terminal to Pohang and then changing to a local bus from Pohang to Gyeongju.
However, when I check the bus provider's website for this trip, it freezes me after displaying schedule with no option to proceed.
Is this the only provider that runs the route? And if yes, am I missing some booking rule (e.g. minimum gap before booking?) since there's an "X" under the "Sale" column?
