I have been naked on beaches all over Majorca - the key is often finding a little cove. Plenty around the coastline near Port Soller.

Hi Zedbed.
Es Trenc (sometimes known as Playa Es Pregons Gran) is good and the largest naturisty beach on Mallorca.
Textile and Naturist happily get on alongside each other.
Naturists tend to congregate between the two main access points, so, a ten minute walk will get you into nuddieland.
On beach bars are ok for refreshments.
Main carpark (5 euros) is near to Colonia de sant Jordi. Turn right near to the salt factory and proceed down the narrow road.
Another beach is Platja Mago near Cala de Cap Figuera. This beach is tiny and overlooked by a bar. It is well used and is handy if you are staying nearby.
Cala Tuent near Sa calobra ......I've seen naturists there.

Tohul says plenty near Soller. That's surprising as we stay at Soller and have never yet seen naturists nearby. Just shows you.. you can never know all of Majorca! I'll investigate next time! 😎

Hope this helps you.
