Programmes K1 and K2: the Whole Park on Foot

What programmes K1 and K2 are

They are the park's two long loops, done almost entirely on foot: K1 leaves from Entrance 1 (Rastovača) and is 16.5 km; K2 leaves from Entrance 2 (Hladovina) and is 17.5 km. The park estimates 6 to 8 hours for either. They only use a short stretch of electric boat to cross the Kozjak; there is no panoramic vehicle.

It is the plan for anyone who wants to see all the lakes on foot, unhurriedly and away from the groups doing the short programmes. In return, it is a whole day of walking, although the gradient is moderate: the water drops about 133 m between the Prošćansko, at 636 m, and Novakovića Brod, at 503 m.

The K1 route, step by step

1. Great Waterfall and lower lakes. From Entrance 1 you go down into the canyon, pass the 78 m Veliki slap and walk the lower lakes along the boardwalks.
2. West shore of the Kozjak. Instead of taking the long boat, you continue on foot along the west shore of the park's largest lake, 81.5 ha.
3. Upper lakes and Prštavci. You climb the chain of lakes above to the Veliki and Mali Prštavac waterfalls and the Tomićevo pogledalo viewpoint, which the park recently opened.
4. Return the other way. You come back through the rest of the upper lakes to the Kozjak and cross to the east shore on the short boat line.
5. East shore and canyon rim. You walk along the east shore of the Kozjak and along the high rim of the lower-lakes canyon to Entrance 1.

The K2 route

It is the same loop starting and finishing at Entrance 2. You go along the east shore of the Kozjak and the east rim of the canyon to the Great Waterfall, climb upstream along the west shore of the Kozjak to the Prštavci and the Tomićevo pogledalo, return through the rest of the upper lakes and finish by crossing the Kozjak on the short boat line to Entrance 2.

Choose K2 if you sleep next to Entrance 2 or want to finish with a short boat ride instead of the final climb out of the canyon.

When to go

Both pass through the upper lakes, which according to the park usually close in winter and reopen in early April, depending on the weather. Do them from May to October, with long days. In summer set out in the first slot to have light and margin; in spring and autumn, watch the closing time carefully.

In November 2026 the entrances open from 8:00 to 15:00 and the short boat runs from 8:00 to 16:00 on demand. The timetable changes with the season: check it on the park website.

Tickets and price

They are included in the general ticket, with day and time slot. In 2026 an adult pays €23 in May and October and €40 from June to September; the afternoon rate is no use for an 8-hour route. Under-7s do not pay; ages 7 to 18, €6 to €15. If you prefer to spread it out, the two-day ticket costs €39 in spring and autumn and €60 in summer, and then you can do a programme A and a programme E on different days.

Getting there and parking

Both entrances are on the D1 and have paid parking, by the hour, paid on leaving. With 8 or 9 hours, allow €16–18 in summer. If you sleep at the Hotel Jezero or in the park campsites, you save the car: the hotel is next to Entrance 2 and from the campsites there is a bus.

What to bring and what to do if the weather changes

Bring water, food for the whole day, a waterproof and light mountain footwear that grips on wet wood. In heavy rain, the boardwalks are slippery and the day gets long: you can shorten it with the Kozjak long boat or the panoramic vehicle, which are included in the ticket. If you are unsure at the start, ask at the entrance about the state of the stretches.

With children or a dog

It is too much for small children; with teenagers used to walking, yes. Dogs may go, always on a lead. Swimming is banned throughout the park.
