Holiday apartment in Grmuša on the Una: rafting and kayak safari

Grmuša is located in the Una Canyon between Bihać and Bosanska Krupa. The named water activities include the Kostela–Luka (Grmuša) rafting route and the “Kayak Safari in the Grmuša Canyon”. The rafting route is 13 kilometres long and has a difficulty level of 2° to 3°. It lasts approximately four hours, including about two and a half hours on the water. The “Kayak Safari in the Grmuša Canyon” lasts two to three hours, is an activity for visitors on the Una, and covers a route with a stated length of 8 to 12.5 kilometres. There are therefore clear differences between the two experiences in terms of duration and route length. The stated time spans and distances each refer to the described activity and do not form one shared route. The geographical references also remain separate: Kostela–Luka is associated with Grmuša, while the kayak safari explicitly mentions the Grmuša Canyon. This keeps the two water activities distinguishable based on their own names and key details. The area around Grmuša is also named as one of the best fishing areas on the Una.

Nature

There is a sandy beach in Grmuša, in the Una Canyon. The water of the Una near Grmuša is described as emerald green.

The “Rotary Kanjon 2026” hike ran from the Željeznički most via Grmuša and Crno jezero to Bosanska Krupa. The “Rotary Kanjon” event was held for the tenth time in 2026.

Culture

The Church of the Holy Great Martyr Pantaleon stands in Grmuša. It dates from 1893 and was consecrated by Georgije Nikolajević, the Metropolitan of Dabar-Bosnia. The church therefore combines a specific construction date with the name of the ecclesiastical dignitary who performed the consecration.

Geographical location

A bridge carrying the M14 main road over the Una is located in the Srbljani–Bosanska Krupa 1 section of the Grmuša Canyon, approximately five kilometres before Bosanska Krupa when coming from the direction of Bihać. In June 2026, Grmuša was also named as a stop for the tourist train on the Bihać–Bosanska Krupa route. Both references concern named transport and route connections around the location.
