Penarth is very hilly, and so it can be quite strenuous to walk here. After I had already walked a lot on the day I visited, I really cursed the winding, steep street leading up to St Augustine!
Some of the streets are very steep, so if you have any walking difficulties, Penarth might not be the best place to visit, or you might need to have a car to get around.
The beach at Penarth is mostly pebbles which make walking difficult, especially for older people, but even on a cold March day there were quite a lot of people - families, people walking their dogs.
The cliffs on which Penarth are built are limestone and alabaster which are soft rocks and have eroded a lot even in modern times, so it is not advisable to go to close to the cliffs.
It is also wise to obey the coastguard warning not to obstruct the ramps where the lifeboats are launched as there might be an emergency.
There is an awful lot of rain in South Wales, especially Swansea and cardiff. Always carry an umbrella or have waterproof clothing from October onwards, as although there may be blue skies, the clouds can quickly appear and rain follows.
