Kaywana Hall is a 15 minute walk to the ferries over to Dartmouth. Leave the front gate turning right and then almost immediately take the left turn into Brixham road, follow this road into Kingswear. You can leave the road and walk along the side of the creek, not advisable in the dark or the wet. The main road through the village takes you down to the two ferries. The little car ferry takes cars and passengers. The passenger ferry is through the archway. The journey is only 4 minutes and the ferries run back and forth until just before 11pm. Once in Dartmouth everything is walkable.
If you want to drive down, there is Pay & Display parking right next to the ferry through the archway. If you don’t want to pay you can park in the village after 6pm and walk down the hill to the ferries.
Be aware the Dartmouth taxis do not cross the river and likewise the Kingswear taxi only operates this side.
