Homestead of Ms A. Jaronytė
There was a barren land next to the backyard of Ms A. Jaronytė. She had the idea to turn this wasteland into a pleasant recreation spot. With a shovel in her hands, she herself excavated several ponds, which gradually filled up with clear water. She fortified the banks with willows. Today, water lilies in shimmering jewel colours cover the water surface. Gleaming streamlets appeared here and there. The place is accented by charming features like the small bridges, a variety of flowers and ornamental shrubs.

Smardonė Spring
The Smardonė Spring was formed by karst processes. Bitterish in taste and smelling hydrogen sulphide, water inspired local people to name it accordingly – Stinky Spring. Nobody used this water for cooking meat or making tea or coffee but everybody considered it good for baking bread and washing. People found that this water is beneficial for sick people: to drink, to wash eyes, or to soak ailing hands or legs directly in the spring. Healing properties of water of the Smardonė Spring were mentioned for the first time in the sources in 1587. When Likėnai Water-cure Resort was opened in 1938, there was no bores and water was drawn from springs, including the big Smardonė Spring. Water was used to treat various ailments, for baths and diluting the healing mud.

Cow’s Cave (Karvės ola)
It is the most famous and best-explored geological monument of nature of national significance (classified from 1964) located in the North of Lithuania. The spot is marked by a wooden post bearing carved inscriptions: ‘Cow’s Cave’ and ‘Nature heritage object’. The Cow’s Cave is a funnel-shaped, almost round sinkhole. According to speleologists, it appeared around 200 years ago. It is 10-12 metres in diameter and around 12.6 metres deep. An opening is at the bottom of sinkhole.

Karst lakelets in Kirkilai
In the region full of sinkholes, this area is unique because of the highest density of sinkholes (more than 200 items per sq. km) and in particular circular lakelets. A circular lake indicates that the lake evolved from a collapsed sinkhole. When a sinkhole collapsed to expose the water table at the surface, the sinkhole was filled with water forming a small circular lake. A footpath runs across area making it possible to have a close look at these exceptional water bodies. This is one of two habitats in Europe where green sulphur bacteria (GSB) and purple sulphur bacteria (PSB) are present, the second one is in Italy.

Most impressive and fascinating, with nearly vertical continuous wall around 7.5 metres high stretches over 80 metres along the riverbed of Nemunėlis.
