There are two shingle beaches in Aberystwyth, a lively but truncated pier, a picturesque harbour / marina that has been dramatically remodelled to provide permanent berths for over 100 vessels, and on the headland between the harbour and town beach are the remains of the late 13th Century Aberystwyth Castle.
The rugged slopes of Constitution Hill (430 ft) have a zig zag path to the summit where you can recuperate in a small cafe' and visit the Camera Obscura for fine views of the bay, but for the less energetic there is the Cliff Railway, built in 1896 and still travelling up and down its steep track.
