Short answer: yes, on a lead, across the woodland and river garden — but not inside the house's café area, which is standard for a National Trust property.
The woodland walk down to the ferry crossing and the wider garden are genuinely dog-friendly on a lead — a proper couple of hours of walking given the size of the estate.
The walk rewards you with a genuinely lovely small beach by the water, worth building the whole visit around rather than treating as a bonus.
As with most National Trust sites, non-members pay for parking — worth checking current rates and bringing your card if you're a member.
Given how close Trelissick sits to Truro, combining a morning here with an afternoon in the city is a genuinely easy, low-stress day.
The King Harry Ferry sits right at the end of the estuary walk, and while the walk itself is dog-friendly throughout, the ferry crossing has its own separate rules worth checking if that's part of your plan.
Spring brings genuinely spectacular rhododendron displays through the woodland, worth timing a visit around if the garden itself is the priority over the beach.
