For a spa break in Khosta, decide what suits you best: a sauna after a walk or a stay with spa treatments. This collection also includes places outside Khosta, so check each property's location.
For walks in Khosta, look around the Yew and Boxwood Grove on Samshitovaya Street and the park on Volodarskogo Street. If you're considering Sirius, Rostov offers a sauna at an extra charge and is about 450 metres from Sochifornia Beach—it is not in Khosta itself.
Compare the facilities and treatments: Grace California has a Finnish sauna and a heated outdoor pool open year-round. Radisson Collection Paradise in Sirius has a spa with a hammam, several types of saunas and steam rooms, massage rooms and a treatment menu.
If separate bedrooms and cooking facilities matter, consider the villas at Arfa Park Hotel: they have kitchen areas, while the resort has a spa and a kids' club. For a simpler stay with a sauna, Rostov in Sirius offers a playground and free strollers, but sauna access costs extra.
