Need help with Taxi's / Hamworthy train station

[CanAnyOneUseThis]

Hi

Staying at Haven Rockley Park in a few weeks time but have 2 questions!

On a Sunday Evening will I easily be able to get a taxi from Hamworthy Station to Haven - any idea which firms to use to book one??? Any idea of cost??
Is it possible to walk it - not clear on Google maps which route to take and is what I think is a footpath over the railway line safe to use???

TIA

If it's anything like us you will need to prebook a taxi, Poole Radio Cabs springs to mind

Ok I thought as much! Do you think they actually work Sunday evenings???

Not sure what time I will be getting the train back until I leave Southampton so will have an hour...

It doesn't look far to walk provided you can use what I think is an unamed road probably a mile?
