Walk up to Nebet Tepe (Sentry or Lookout Hill) for the panoramic view of Plovdiv and surrounding mountains in the distance. The remains of the earliest settlement in Plovdiv are randomly scattered stones and some bits of wall but the vibes up here are very calming. Evidence has been found that the site was settled as early as 12th century BC as the ancient Thracian town Evmolpiya and later expanded by Philip of Macedonia. As the town expanded, Nebet Tepe became the citadel of the town's acropolis, the highest point of the three hills. There are remains of a fortress wall and tower. There is also a secret tunnel from the time of Justinian (4th century) leading down to the Maritsa river.
Just before you reach the top, the restaurant 'Rahat Tepe' provides some much needed refreshment.
