Walking in the valleys are alternatives for exploring the summits. Besides, not everyone has the condition to enter eg. On Swinica and the valleys anyone can go through. You can even grab some small children in wheelchairs.
Very nice valley in the Polish Tatras part of this;
• Koscieliska Valley,
• Chochołowska Valley,
• Strazyska Valley,
•Valley of five Ponds,
• Valley Fish Brook.
During the summer there are many tourists, but you can hit for less traffic, winter density also varies both in the valleys and slopes.
