Singleton park is a lovely park in Swansea with lots of trees, ponds and plenty of benches o sit n enjoy the view. You can walk through here to get down to the beach as well. There is a stream that runs along the edge of the park that you can walk next to. There is a coffee van in the park and public toilets next to it.

The Marina is a great place to run. It is really flat and you can run past all the boats along the paths. The beach is close by and there are cafes and pubs that you can start or finish it. There's also public toilets there and there is a nice 5k loop or more

Great place to go running. You can run along the beach or there is a path that runs parallel to the beach which is flat and wide enough for runners.

A lovely cafe and bar on the sea front. They do lovely coffee and the food is great too. Great place to stop when you’re going for a walk on the beach! Dogs are allowed and there’s indoor and outdoor seating

Enjoy unobstructed views across Swansea Beach on this long flat section of paved path that follows the coastline. On a clear day you should be able to see all the way over to Mumbles Head, which marks the start of the Gower Peninsula.
