Walk in The Lost World An easy walk/ mountain bike ride with not so many spectacular views, but a glimpse into an amazing underground world.
Because of the extreme tectonic activities and the effects of water erosion, numerous sinkholes are formed on the north side of the Grabovička mountain . A sinkhole is a funnel-shaped or disc-shaped recess with a stone or earth bottom. It is also known as a cenote, sink, sink-hole, shakehole, swallet, swallow hole, or doline, and represents a depression or hole in the ground caused by some form of collapse of the surface layer. Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks or suffosion processes. Sinkholes vary in size from 5 to100 m both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Surdup is one of those sinkholes, and is located on the pedestrian road between villages Drmića staje and Kovači.
The Kovači Sinkhole represents one of the most important speleological objects in the area of Tomislavgrad. The entrance to the sinkhole is located in Kovači village at an altitude of 848m, just beneath the Grabovička Mountain. The sinkhole exit is located on the eastern shore of Buško Lake.
Mali Samograd is a deep pit that has an enormous vertical drop at the beginning, and is linked with a large sinkhole called Arnautovac. The vertical entrance is a 80x45m hole, from where it goes down to the first floor of the pit, which is about 40m deep. The first floor has extremely steep walls covered with hornbeam trees. This leads directly to the underground entrance, which locals call Rogoševac. The entrance to Rogoševac, which is 16m long and 12m high, is situated below the rocky cliffs 90m below the karst plateau. The length of the main channel of the cave is 135m, while the other side channels are over 250m long. The depth of the pit is 150m. Source: Natural heritage of Tomislavgrad (2013).

In the area of Duvno karst, on the karst plateau of Grabovička mountain, there is a deep hidden sinkhole 19m long, 110m wide and 40-60m deep. It’s called Samograd. (Translation: self-formed.) It is a huge oval sinkhole with very steep cliffs vertically descending from the karst plateau. At the bottom, at the foot of the eastern cliffs, there is a cave entrance 3m high and 7-10m long. The cave itself is 15-20m long and it has one 5-7m long hall. Source: Natural heritage of Tomislavgrad (2013). Tomislavgrad, Zagreb: Our Heritage.
Dahna Cave is located above Omerovići village, at the western part of Duvno field. It has a small entrance (1x1m), hidden in a hornbeam tree forest, under a rock covered with moss. Beyond the entrance space, there is a larger hall 20m long, 6 to 7m wide and 1 to 4 meters high. The ground is covered with dirt and small stones. From there, the path goes to a narrow, low channel that has a very wet bottom and is also covered with small stones. At the end of this 15m-long channel opens the 720m-long channel, called a main or a major channel, and a smaller one 60m-long, where pottery artefacts from the Roman period were found. The total length of the cave channels is 1100m. The cave has not yet been arranged for tourist purposes, but is very attractive to archeologists, paleontologists and biospeleologists.

Listvača cave is located on the karst plateau of Grabovička mountain near the village of Gornji Brišnik. The terrain in this area is quite flat, so it’s easy to access the cave. The terrain was once a large pasture, dominated by valleys and depressions whose flattened bottoms were used as farmland. Listvača is one of the most beautiful caves in the Duvno area. The entrance is semi-circular in shape. It is 20m wide and, in the central part, around 3m high. This entrance area can be reached via steep stone slabs in which aromatic herbs grow in the crevices. Shepherds used this part of the cave as a shelter from bad weather. At the end of the great entrance area, you will enter into an unreal atmosphere of calcite carvings, which mark the continuation of the cave. The total length of the cave is 103m.

Mijat Tomić was born in the village of Brišnik near Tomislavgrad. Although his exact birth date is uncertain, Mijat is said to have lost his parents at a young age, and by 1640, was known to have had at least two brothers and two sisters. As a child, Mijat was reputed to have been physically strong, a characteristic that was later proven in future battles. One legend states that he won while competing in some games popular with the locals. The defeat did not sit well with the Ottomans and they decided that he should be killed. Mijat then fled to the mountain Vran, marking the beginning of his life as a hajduk. Facts about the life of Mijat Tomić were published in the 18th century book "Cvit razgovora naroda i jezika iliričkoga aliti rvackoga" (1747) by Franciscan priest, Filip Grabovac. In reference to Tomić, Grabovac claimed that, following his death, there "never existed a real hajduk like him nor will there ever be one". Mijat Tomić died on or around July 20, 1656 (on the feast day of St. Elijah) in Doljani, a settlement near Jablanica in Bosnia-Hercegovina. Many poems and legends are in agreement that he was betrayed by his godfather, Ilija Bobovac. A Venetian source about Mijat's death states that there were more cheers in Sarajevo on the news of his death "than when news arrived about the capture of Baghdad" a few years earlier (1638).

The entrance to the Great cave is a high, spacious ceiling under which, from a very narrow hole, a stream bursts and spreads in the lowlands. This powerful stream once served as a driving mechanism of the millstone, which people used to grind grains. This point is best accessed during the dry season. When the creek dries up, it is possible to enter the cave through a narrow channel for about 40m. After that point the ceiling lowers down, preventing further progression. Because of its natural ambience, this cave - which locals also call the "cathedral" - served as an altar in the time of Turkish oppression.
Located on the main road M15., on the Tomislavgrad-Posušje section, the salon and restaurant Lovre offers accommodation. It is also adequate for weddings and other big celebrations.
