The walk starts by the ruins of Aberystwyth Castle, which are well worth taking some time to explore. The view south from the castle to Pen Dinas and the Wellington Monument which sits on top of the hill is sublime, as is the view of the coastline extending south into the distance. You will be looking with eyes wide open for a while at that view. After tearing yourself away from the beautiful spectacle, the walk extends on an enjoyable promenade stretch beside Aberystwyth's coastline, past the seafront buildings of Aberystwyth University and the Royal Pier, continuing along Marine Terrace, extending to Victoria Terrace, and eventually reaching the foot of the climb up Constitution Hill.
You may be tempted to avoid the 400-foot (120-metre) climb by taking the cliff railway if it is open, but resist the temptation and make the climb — you will feel better for it. The cliff railway leads to the Camera Obscura, an octagonal tower in which the entrance fee gives you access to a 14-inch (35-cm) lens system that projects detailed live views onto a screen in a darkened viewing gallery.
After Penglais Woods, there is a view across Aberystwyth. The most eye-catching buildings of the town can be identified, including the university buildings, St Michael's Church, and notably the National Library of Wales. An Englishman, Stuart Rendel, gave the land for it in 1897. This splendid building houses millions of books, maps, pictures, and manuscripts, including the 12th-century Welsh Black Book of Carmarthen.
A trip to Aberystwyth would not be complete without a ride on the Vale of Rheidol Narrow Gauge Steam Railway. Opened in 1902 to serve the lead mines, it runs inland for nearly 12 miles (19.2 km) at a gradient of 1:48 to Devil's Bridge. Trains run from the station, which is also the terminus of the standard-gauge line from Shrewsbury.
