Monodendri is the long pebble beach north of Loggos, and the most developed on Paxos. It appears in the coastal survey of 1885 simply as the spiantsa at Monodendri, one name among dozens on this shore.
It is no longer a quiet one. A walker who recorded these paths in 2012 already described the development here as extensive and rather brash: large car parks, loungers along the whole length, the beach divided between three owners, water sports and terraced bars at the north west end and a restaurant in the middle. Visitors today say much the same, and Monodendri scores lower than the quieter beaches around it for exactly that reason.
What you get in exchange is everything on the spot: two beach bars, food, sunbeds, water sports, and road access with parking. What you should know is that the sunbeds are not free, and in high season finding parking that is not attached to one of the businesses is difficult.
If you want this coast without the crowd, Orkos and Lakkos are a few minutes north.
