Callor Millor is one of the main towns in the north eastern corner of Mallorca. It has a real town center, and a long attractive beach, lined with hotels, shops and restaurants.
It is a one hour drive from Palma, the Palma airport, and towns like Alcudia in the northwest corner.
Millor is along the long beach, and things are within a walking distance (maximum 20 minutes).
The beach is nice and pretty, but very crowded in the summer.
The rocky peninsula of Punta de n'Amer starts from the southern end of the beach, and is good for short walks and hikes. There is a small "castle" ruin in the middle of the peninsula, with a small cafe, serving coffee, pastries, and drinks.
Puig de na Penyal is a hill 2 kilometers inland to the west from the center, with great views to the town and the eastern coast of Mallorca. There are hiking paths to the top.
There is a large collection of hotels in Millor, ranging from modest 2-star places to several luxury hotels. Rates are low in winter and high in summer.
