Short answer: typically assistance dogs only inside the National Maritime Museum itself — a genuine, reasonable limit given the enclosed galleries and the tower viewpoint.
Much of the museum experience involves lifts, narrow gallery spaces and a lookout tower with other visitors moving through close quarters — genuinely not an easy environment for a dog even a well-behaved one.
Falmouth's harbour front, a short walk from the museum, is genuinely dog-friendly and pleasant, making it easy for one person to visit the museum while another walks the dog along the water.
Museum dog policies can be updated, so it's worth a quick check before you travel if this is a genuine sticking point for your visit.
Splitting the group — museum for some, harbour walk for others — tends to work better here than trying to make the whole day dog-inclusive around one indoor attraction.
Given how close the harbour front sits to the museum, splitting a visit — one person inside, one walking the dog along the water — is genuinely the most common practical solution here.
Falmouth's working harbour genuinely has plenty to watch — fishing boats, sailing schools, the passenger ferry — making the alternative dog walk a proper activity rather than just killing time.
