Great destination for a tour, the latest here has everything to offer, what you need for a good trip: blue mountain lakes, rough mountains, warm food and cool drinks;) Dogs are at the Coburg hut no problem.
The climb is worthwhile, but it is also difficult. The view later on the Seebensee and the Zugspitze then compensates for the ascent. The dragon lake is also beautiful and you have a great panorama. Unfortunately, it is very crowded in summer.
