A lovely hidden gem, it’s just off the main road but you feel like you could be anywhere 😍 it has a museum here, a cafe and some facilities open during the day. There is free parking and you can access it at anytime as there are no gates but the actual facilities and museum only open during the day. Lovely meadow and pond to walk around

Lovely park in Carmarthen. You can park at Tesco and walk round here as long as you’re shopping of course 😬 it has lots of benches, a park, a nice velodrome which is good to sit and watch people. Nice little hidden place in the town

Test your speed on the Carmarthen Velodrome. The velodrome is just over 400 metres long, and was opened in 1900, and is believed to be the oldest outdoor concrete velodrome in continuous use in the world. Members of the public are able to access and use the cycle track (not the changing rooms) free of charge Monday to Friday between 9am and 6pm, Sundays (all day) and during other specific periods as determined by CTC.

Carmarthen Roman Amphitheatre is one of only seven Roman amphitheatres that survive in the UK. Dating to around 75 AD, the amphitheatre would have been the social centre of Roman Carmarthen. These days, it's a pleasant place to stop for a moment to soak in the history.
