Gweek is not very far from Falmouth so we have visited the National Seal Sanctuary many a time and it has been great every time. It is the busiest seal rescue centre in Europe and the staff work to rescue seal around the coast then care for them at the sanctuary. Most of the seals and sea lions are only at the sanctuary temporarily before they are returned to the wild once they have recovered but some are permanent residents due to an injury or illness that means they would not survive in the wild.
Watching the seals and sea lions is really great fun.
They are so elegant in the water yet so cumbersome on land - very funny to watch. Each animal has it's own information sheet, which is displayed next to the pool it lives in and you are told why it needed rescuing, the treatment it is undergoing, when it will be returned to the wild, it's personal habits and of course it's name. It's fun to read about them and then try and identify them in the pools. It's actual quite easy to do this because they are all quite different - the fact that half of them have eyes missing or large scars helps too.
In recent years they have also added a couple of otters to the sanctuary, which are fun to watch. There is also a quiz that has been there since we first visited the place many years ago. It is of course about seals and sea lions and the questions are dotted around the sanctuary and you have to uncover the right answer on a sheet you are given (it's kind of like a scratch card where you scratch the silver covering off with a coin to see if you got the right answer or not). It's intended for young children but I still have a go - thankfully I get more of the questions right now (without cheating).
The Seal Sanctuary is great fun and I would recommend it to anybody in the area.
