Boscastle is poorly connected, and no amount of coastal charm changes the timetable. There is no railway. Eight bus stops serve the village. More than half of working residents drive, and nearly half of households run two cars or more. This is a place you reach by car, leave by car, and think carefully about before selling one.
On public transport, the rail picture is the shortest section of this answer: no station, and under 1% of residents commute by train. Buses are the whole of the network here, with eight stops across the area and a bus commute share also under 1%. The stops exist. Whether they constitute a service is a question the timetable answers further down.
The commute mix tells you how people actually solve it. About 55% drive to work and around 30% work from home, which between them account for most of the working population. Roughly 9% walk, and cycling is under 1%. On the census count, about 48% of households have two or more cars and only about 8% have none. In a village of this size, that second car is not a lifestyle choice, it is infrastructure.
For everyday distance, the Department for Transport's modelled journey times put the nearest town centre at about 34 minutes by car and 63 minutes by public transport, with roughly 79 minutes by bike and a walk that runs to the modelling's two-hour ceiling. These are modelled figures for the area rather than a route from any particular front door, and the public transport numbers date from 2019, so treat them as generous rather than pessimistic.
Broadband is the one part of the connectivity story that works properly. Superfast service reaches about 97% of premises, gigabit-capable service about 37%, and no premises fall below the universal service minimum. For a village at the bottom of two river valleys, that is a better result than the roads managed.
Mobile coverage is similar. Fourth or fifth generation service from at least one operator reaches effectively the whole area, and about 95% has coverage from all operators, so the network you are already on will probably work.
The same modelled statistics cover everyday destinations, and they are the numbers worth reading before you commit. A general practice sits about 13 minutes away by car, 25 by bike, 28 by public transport and 63 on foot. A food store is roughly 10 minutes by car and 37 minutes walking. A hospital is about 83 minutes by car, and by public transport it hits the two-hour modelling ceiling. The nearest sizeable employment centre comes out at about 89 minutes by car and 77 by public transport, which is one of the few journeys where the bus is not obviously the slower option, mostly because the car figure is already so bad.
Current service data is blunter than the modelling. Across the six stops with published service information, the average is about six scheduled departures per weekday, with an average of zero in the peak hour. All six do run something at weekends. Six departures spread across a day is a lifeline service for people without a car rather than a commuting option for people with one.
Road noise is a non-issue. None of the area's postcodes sit near the 65 decibel threshold at which official mapping treats road noise as significant, and the same is true for railway noise, for reasons that are by now familiar.
Electric vehicles need planning. The area has one public charge point with two connectors and no rapid units at all, so charging here is an overnight activity at home rather than something you fit in around a supermarket run.
Connectivity is the weakest thing about Boscastle by a distance, and it is not a fixable weakness. Buy here having already decided that the car is doing the work and the broadband is doing the commuting.
