Croatia's twin national park?

Hello, most of Croatia's island-jumping trips in the market only go to Pres (Sixteen Lakes) National Park, and also go up and down the lake. Some trips only go up and down the lake, but most of Kokka National Park don't go. I recommend hiking. Both Pres and Cokka National Park are the most beautiful national parks that pass through Pres National Park (upper and lower lakes). Established in 1949, it is the second national forest park in Europe. There are sixteen lakes in the park, and countless natural waterfalls have been formed due to the difference in height. Coupled with the karst terrain, travertine steps can be seen everywhere in the park, so it is called "Sixteen Lakes National Park". The landscape with four distinct seasons presents a different face from canyons, waterfalls and lakes, and varies with the depth, height and mineral content of water. The scenery in the park is even better than Jiuzhaigou wonderland in China. First, I went to Shanghu District. The scenery is famous for its magnificence. There are dense forests, clear blue lakes and swift waterfalls, between mountains and green hills. Walking to the high place of the canyon, overlooking from top to bottom, you can see lakes, large and small, connected by layers. And take a boat and cross the green lake. The Lake District is famous for its exquisite and beautiful scenery. The longest waterfall in Huxia District is located here, 78 meters high, connected by layers. The splash caused by waterfall water is matched with the gurgling river, which makes people lament the greatness of the creator. Cokka National Park was established in 1985, covering an area of 142 square kilometers. The main protected area is the middle and lower reaches of the Cocca River. Due to the limestone terrain cut by the river, the national park can see the travertine steps with a great drop, forming a beautiful waterfall landscape, especially the largest Kirkka Waterfall, where silver curtains are intertwined and stacked, splashing water into fog. We specially arranged a boat trip to the Cocoa River, enjoying the beautiful canyons, waterfalls and lakes around us and the colorful scenery of yellow-green, light green, dark green and blue-green under the sunshine, and feeling the calm and clear of the river. It's well worth a visit. The hiking trip includes a one-night stay in Montenegro, avoiding the long-term customs clearance.
