Peştera Comarnic is named after the nearby Canton Comarnic, a forestry hut. It is the biggest cave of the Banat, the mountainous area in the south western corner of Romania, north of the Danube. Near the huge building of the forestry service is the small hut of the speleologists. The meadow here is a possibility for camping. It is also the meeting point of the road and numerous walking trails.

The cave has three different levels. The upper level, etajul superior is dry, the lower level etajul inferior is an active river cave. The middle level is sometimes flooded, during times of high water. The tour shows most of the upper level, which is rich in speleothems. Only the Sala Virginá (Virgin Chamber) is not accessible to the visitors, to protect it from damages.

Twenty years ago it was a typical Romanian show cave, there were no regular tours or open hours. During summer Jerry aka Romulus Vuia lived at the forestry hut. He guided anyone who came along, even foreign tourists as he speaks French and a little English. After appointment guides fluently speaking German and English are available too. They were organized by the local caving club, who did exploration and cave trekking tours.

This has changed in 2000, when the cave became part of the new Parcul Național Semenic-Cheile Carașului. The cave is now officially managed by the National Park. There are regular open hours on Weekends during summer and three scheduled tours. Nevertheless, it is still possible to make reservations for groups, even in foreign languages. Some rough parts of the trail were developed with stone steps and railings, but the cave still has no light. We recommend to bring a helmet with a headlamp and good walking shoes. However, helmets and lamps are provided by the guide to those without. Despite being rather rough, this is a walking tour, there is no crawling or getting dirty involved. The cave is closed with a gate and it is not possible to visit without a guide. While there is a fee for the cave tour, you also have to pay the fee for the National Park. According to their website:

Send an SMS to the number 7473 with the text: “SEMENIC”, for “PRODUCT NAME”. SMS cost: 2 EUR + VAT. You will receive a confirmation SMS as soon as possible. Keep this message during your visit! The lack of a confirmation SMS means that the payment has not been made. The visiting rate is valid for two days from the date of issuing the SMS.

The Pestera de la pârâul Ponicova is the same cave system but another entrance. It is the resurgence of the cave river which sinks at pârâul Ponicova, pârâul is the Romanian word for sink, swallow hole or ponor.
