Rafting on the river Cetina lasts for about 3,4 hours on the 10 km long route which ends in a restaurant called Radmanove Mlinice. All you need is swimsuit, a pair of shoes suitable for water. You can bring your camera with you too. It is placed in a small waterproof barrel inside the boat. Everything else, equipment (paddle, helmet, buoyancy aid) you will be given before big adventure begins and also quick tutorial for basic rafting skills.
Cetina is a pool drop river and on the scale of 1-6 it's classified as a 2-3, which means that the rapid is easy and medium. You will see nature in it's best, beautiful lakes, vegetation cliffs, waterfalls, cave..
There is one section of the river where you have to walk for abt. 100 m because the rapids are a bit tougher for total beginners.
My favorite part of the rafting trip was jumping from 5 m high rock into the river. FUN!! :))
Although, river is quite freezing (abt. 8-10°C in summertime).
There are plenty of tourist agencies all over Omis offering rafting tours. I have given information of only one, the one we took.
Price for rafting trip is abt. 180-200 kn/person. There are several "agencies" offering much lower prices (usually abt. 100 kn/person) but beware of that. I wouldn't recommend taking these trips; they usually don't have enough experienced and educated staff.
The River Cetina runs into the sea at Omiš and, if you follow the east bank inland, you soon reach the start of the gorge, (within sight of the town). The lower reaches of the river are attractive enough but the scenery becomes more spectacular as you move onwards. You can travel more than 20km on the road through the gorge, finally climbing out of it near Zadvarje. The first part of the journey would be reasonable bicycle country, the latter part much less so. If you are driving, you may find that some of the route is not exactly relaxing. (The initial part is no problem.) There were some diversions (e.g. via Svinišće) when I was there recently. These produced some particularly fine scenery - and, in retrospect, it was worth the uncomfortable driving involved!
The old town of Stanici includes those narrow alleys and old buildings that are great. It is only very small though and gets packed in the summer. There are only two of the passageways that have any shops or restaurants and the rest is still a residential place. We found one great place to eat in the one square we found, sorry cannot remember the name but it was the best place as it had a bit of space, many other tables are cramped in the main passageways.
This is a spectacular steep gorge that runs behind Omis. You can take a boat trip about 5km up the river which stops at a restaurant, take a car or take a raft back down the gorge. In the car, you can go further back but on the boat you see more. The road took us away from all of the crowds on the coast.
South of Omis there are a number of small villages that have been clustered into a 20km stretch calling itself the Omis Riviera. Each of these villages have expanded in recent years with many apartments to choose from. Each village has a steep climb down to the beach. The beaches tend to be deep water and pebble/rocks. We had great fun here. The villages include Nemira, Stanici (where we stayed), Ruskamen (one of the larger), Lovka, Medicic, Mimice (large again), Pisak. There are a smattering of restaurants in each with info points and facilities at the larger places. The website has more info.
The towns of the self styled 'Omis Riviera' covers a number of small villages along the coast south of Omis. Each of these has a beach or two and each beach we saw were similar, pebbly/rocky with a climb down and up form the main road. None of the beaches were in particular better than others so we ended up at the one that was most convenient to our apartment and if you are staying here this is a big bonus of the place. My real tip therefore is find the beach that is most convenient to you, be it close to accommodation and/or parking and choose that one, you will not find the next one along much better or worse. Facilities are similar at these with a small cafe/bar but little else. A pleasant change from the busier resorts.
There is no getting away from it, the beach and the sea is the reason that most people travel to this. Omis has two beaches. The main one and closest to the town centre is the more popular and shingle, the less popular one, a short walk away is sand, yes sand in Croatia. This is a great beach for youngsters as it is easy on the feet and shallow, allowing paddling a long way out. There is a camp site directly behind this beach so don't expect it to be that quiet but there are a few stalls, activities such as windsurfing and boat hire and showers and changing areas.
Velika plaža(The big beach) is sitauted in the very center of Omis, it is easily reachable in just few minutes walk from the center . This 700 meters long sandy beach is ideal for families with small children and young people. It offers lot of activities such as volleyball, football, windsurfing.Other beaches are Brzet,Slavinj,Nemira,Mimice...
At the peak of their power, Omiš Pirates were one of the most powerful and fearsome pirates on the whole Mediterranean Sea. In the 12. and 13. century Omiš was governed by the dukes Kačićs, the leaders of the pirates of Omiš. The Omiš dukes where so mighty that the towns of Dubrovnik and Kotor were forced to make treaties with them on non-attacking, and in the 13 th century even Venice appeared as a party in the pact with the Omiš pirates making a commitment to pay tribute to ensure free sailing and trade. The pirates of Omiš used to attack Pope's galleys and merchants of Venetia, Dubrovnik, Kotor, Split. Omiš Pirates ruled the Adriatic Sea for more then three centuries until in the year of 1420 the whole of Dalmatia, except Omiš, fell under rule the of Venetian Republic, the most powerful naval force of those times. Surrounded by the enemy and left completely alone, the Pirates of Omis managed to defend themselves for 24 years.Today every summer during the Omiš Cultural Summer people get together and celebrate with they guests Omiške gusarske večeri (Omiš Pirates Nights)
The frontier of medival Omiš together with the region Poljica was the river Cetina.Above its canyon on the lower Cetina frontier Fortresses Kunjak and Visuć were built to defend the district of Omiš .The fortress Starigrad (old town) was first mentioned in the 1423.The fortress is situated at the top of the mountain Omiška Dinara over Omiš,with the strategic view on all movements across the middle Poljica as well as over the navigation in the channel between Omiš and the island Brač .
Mirabella is Romanesque fortress, built in 13th century above the town. Mirabela or Peovica was a reliable hideout for the Omis pirates who used to retreat into the safety of the Cetina gorge. There is an interesting story about Mirabella. In 1537, during an attack by the Turks, the defenders of Omis confused the attackers with their shouting and shots so much that the Turks overestimated the number of defenders and fled. A favorably chosen position on the tower will multiply any sound with echo, which will be aided by the river, making it impossible to locate the source of the sound.
Don't miss the main happening of Omis Cultural Summer -“Festival dalmatinskih klapa” (Festival of Dalmatian folk songs), which is being held, on regular basis, every year since 1967. It helped in cherishing and keeping alive the tradition of folk singing, which is praised all over the Europe. This is based on a capella singing, and the lyrics bear witness to hard life of Dalmatian fishermen and peasants
You can rent a canoe from the restaurant Radmanove Milnice and paddle on the Cetena river. Small canoe costs 30 and bigger one 60 kunas for an hour (2007).
No earlier experience needed, you can be a complete novice to canoeing. For rafting, continue for a few kilometers upstream.
Omiš museum is situated in the historical town center. The Town Museum houses a collection of artifacts from Omiš history, an archeological collection and the Poljički Constitution.
