Best things to do in Kleve

Walk through the ancient Roman city of Colonia Ulpia Traiana at LVR-Archaologischer Park Xanten, Germany's biggest archaeological open-air museum. The town was established as a Roman military camp in 12 BCE, but, unfortunately, nothing remains from those times. Luckily, excavators and archaeologists have redesigned the major buildings in the park to the scale and architectural precision of the Roman originals. See the harbor temple, the amphitheater, the city walls and gates, and Roman houses as they would have appeared in their original places. A ticket to the park also gets you into the Roman Museum, which gives a history of the Roman life in the Lower Rhine area and contains the remains of the Town Baths.

Wunderland Kalkar is an amusement park in Kalkar, North Rhine-Westphalia, Germany. It is built on the former site of SNR-300, a nuclear power plant that never went online because of construction problems and protests. The park was constructed by Dutch entrepreneur Hennie van der Most, who purchased the site for a rumored price of US$3 million. Wunderland Kalkar receives around 600,000 visitors each year.
Many of the facilities constructed for the plant have been integrated into the park and its attractions, including the cooling tower, which features a swing ride and a climbing wall. The park also features four restaurants, eight bars, and six hotels.
