Located right next to Mylna Cave (in fact, connected to it) is the Obłazkowa Cave is located some 130m up from the bottom of Kościeliska Valley. The main cavern can be visited without a flashlight, but a source of light becomes indispensable if you want to venture beyond, into the very very tight corridor leading to the back of the cave. Get here from Pisana Polana in the Kościeliska Valley via the red trail; it takes about 15 minutes to walk up, and afterwards you can continue through Mylna Cave (one-way trail) or walk down the same way.
