georgian beaches sand or pebbles? was asked on Lonely Planet where for Abkhazia:
• andrewsmith: The sand in Abkhazia isn't great either. Sokhumi beach is mostly pebbles and only gets snady once you're in the water. Unfrotunately, there are many submerged hazards, remains of recks and old jetties etc as there's no organised government to clear this up. There's a bit more sand at Gagra.
Do the Black Sea coast of Abkhazia sandy beaches ? was asked on quotesis where:
• Знаток: There are beautiful sandy beaches on the shores grow pine.
However this recollection (from about 30 years ago) may be 'approximate', or at least not representative of the coast as a whole.
• galvanna: there is a sandy beach in Gagra, Gudauta
However galvanna seems to have made a long trip to Anapa (Russia) specially for the sandy beaches there.
• miss-olly: Wonderful beaches, sandy little pebble in the main, but clean water and wonderful scenery.
There is a picture under Beaches in Pitsunda that appears to show sand rather than pebbles. However all best tips mentions for Pitsunda: sandy beaches and small in size, but cozy and there is also a beautiful beach with clean sand, which is located on the pension "Musser" and The village also has Lidzava sandy beach. It is surrounded by pine forest. From Pitsunda it is located 3 kilometers. For lovers of quiet places it will fit most. The same site has for Sukhumi: pebble beach or mixed gravel and sand.
