Not a lot as far as facilities go but a great friendly site that is rib and pet friendly, kids play area and toilets etc.
You can then launch at Bude, tidal but a lovely run up to Lundy, plenty to see around Bude, Boscastle etc.
Port Gaverne has a camp / caravan site and a good beach launch at all tides - if you have a 4x4 or like pushing. Lundy will eb a fair run but Rock, Padstow become easy runs.
If the weather is grim Plymouth and all the options there is an hour away.
Other options are Porthkerris - they will launch you and can provide a bunk house and camping - Self Catering Accommodation & Camping at Porthkerris -
Pentewan Sands can also launch accross teh beach and has some well known accommodation options - Pentewan Sands Holiday Park - Caravan Holidays - Camping Cornwall
Being nosy which bit of North Dorset? I used to live Sherborne.
Hope it helps?
