The city is quite smart with trees along the main avenues and lovely views of the surrounding mountains from many locations. As Denizli has prospered in the 90s new compounds of luxury villas have sprung up on the city's outskirts in areas like Çamlık. In the city itself air pollution from coal-fired central-heating becomes a problem in winter. There are some highly-regarded high schools and Pamukkale University opened in the 1990s, now in phase of academic maturing. Many young people still leave to go to university in İzmir, Ankara or Istanbul, and sometimes stay there to build careers.
