Ooh how lucky you are. I love it there.
Ok, so. Get the castle ferry from the embankment. It’s a little blue wooden ferry boat, costs approx £2.50 to go to the castle. There’s a little cove there, walk down the steps if the tide is out it’s great for exploring, if not you can sit on the steps and watch the water. Walk back, takes 20-30mins depends on how long you linger. Lovely to see all the houses, boats.
Eat at Rockfish, book online, really easy and means you’ll get a table. It’s very popular. You only need book a bit in advance. But you’ll secure your table.
There’s also a boat trip you can do to Greenaway. It’s the ferry. £5 return it’s the cheapest boat trip you can do, it’s great and you see loads. Lasts 1hr.
Take a walk along to Bayards cove. Ruined defences of the town.
I’ll be back when I think of some more.
