In case you will be ready to have fun close to the water during the hot day I offer to visit one of seven lakes.
One, called Bridvaisis is quite nice and easy to reach. There are camping place close to the water where you can order a small house for the night. In the middle of lake are two islands. One is reachable from the cost. There is a bridge to it and second one you can reach anly with a boat which you can rent on the cost.
Second of biggest and closest lakes is Gylis. It meen - deapness. This lake formed from hundreds of streems and is always cold. There is a way for tourists to see qhat is around this lake. During that trip you will notice beutiful landscape and will have possibility to dring fresh and cold steerm water.
Other five lakes are mch smaller and more difficult to reach.
