Some places to visit in Cardiff
In the city centre you have Cardiff Castle and Millennium stadium, Both good places for photos
On the outskirts of the City you have St fagans Meuseum of Welsh life, this has various buildings that have carefully been moved to the area that are old. Some are fully furnished and as they were a century ago. Plus nice features for a day out.
You also have Cardiff Bay and the Cardiff Barrage both worth a visit.
Dr who series is filmed in Cardiff, when down the bay why not visit the Dr who Experience.
Other castles close to the city are caerphilly castle and Castell Coch
The Brecon Beacons National park is stunning in summer, and great fun in winter when it snows, many people take their children to sledge down the mountainside. In summer a walk to Pen Y fan ( Highest peak of Brecon beacons ) offers stunning views.
The Garrison town of Brecon Is about 35 miles from Cardiff and has the borders museum. This has a lot of stuff from the hawkes drift battle ( Zulu film)
Brecon has a nice park to relax in summer.
Further West towards the Swansea valley you have Dan Yr Ogof showcases, definitely worth a visit and about hours drive from Cardiff
back to the city and you have techniques down Cardiff bay, a lot of fun for the kids and adults
November the 5th is bonfire night and normally on the weekend around that date we have Sparks in the Park.
So if in Cardiff around that time go and watch a spectacular fireworks display.
Winter Festival starts around December and a small fun fair and out door ice skating ring is found opposite city hall which is near the castle.
For those that like to party the main streets on weekends are around St marys st. There is another area frequented by students by the Hilton hotel.
You can get a all day bus pass in Cardiff for about £3.80 which allows you to travel about.
Roath park and victoria park are both great for kids, the former very nice for adults to enjoy park.
There is a large indoor pool with great water slides near Cardiff bay and an ice skating rink at same location.
Hope that gives a insite
