The Monsoon Forest habitat and award-winning gardens add plenty more to see.

Tip: Book online in advance to save on gate prices, and parking in the zoo car park is free.

The Welsh Mountain Zoo is a zoological garden near Colwyn Bay in Conwy County Borough. It covers 37 acres and has been open since 1963, so it has built up a good range of animal areas over the years.

Tip: Check the zoo's website before you go, as the sources note that animal exhibits such as the sea lions have changed over time.

Conwy Castle was built by Edward I between 1283 and 1287 and is part of a World Heritage Site. Eight large towers and a high curtain wall still stand, and it has the best preserved set of medieval royal apartments in Wales. The ruins are split into an inner and an outer ward, with a Great Hall undercroft and chapels to explore.

Tip: Climb the spiral staircases and walk the full battlement circuit if you can. Cadw highly recommends it.

Flint Castle (Castell y Fflint) was the first of the castles built during Edward I's campaign to conquer Wales, and it sits on the western shore of the River Dee estuary. Its ruins are looked after by Cadw, and access is free via a path. Most of the site, including the keep, is open to the public.

Tip: Head for the spiral staircase in the north east tower to reach the viewing platform over the estuary.

The copper mines on the Great Orme were uncovered in 1987 during a landscaping scheme. They date from the Bronze Age, long before the Roman invasion, and are thought to be the largest prehistoric mine discovered in the world so far. Archaeologists, cavers and mining engineers are still uncovering more tunnels and surface landscape.

Tip: It's cold underground (5-8°C), so bring warm clothing and sensible footwear; the floor is uneven and wet in places. Pushchairs and wheelchairs can't do the tour.

Plas Newydd in Llangollen was the home of Lady Eleanor Butler and Sarah Ponsonby, two Irish ladies who eloped and set up house together in the late 18th century. It began as a five-roomed stone cottage and was enlarged with many Gothic features. It is now a museum.

Tip: Look closely at the outside of the house as well as the rooms, since the patchwork of reclaimed oak carvings is its most unusual feature.
