About 3 miles long. While the beach is relatively sandy, it's not that picturesque. There is an excellent cycle track the entire length and is fun to walk when its cold and windy. Can also be used for water-sports and fishing.
The best attraction in Colwyn Bay, while not a large zoo, the interesting location on a hillside (not quite the 'Mountain' advertised) allows for more interesting habitats for animals. A free bus usually runs from Colwyn Bay train station. However, check the zoo's website to find out when it's running.
A large, grassy park about 20 minutes walk from the town centre. As well as the park with its boating lake, there is a fairly well equipped leisure centre with indoor pool, squash and tennis courts, and a good athletics track. There is also a new skate-park on the grounds
On the promenade is the town's "Victoria Pier" which is in a sad state and in dire need of renovation.
