The Cave Spa

The Cave Spa sits inside Ycona Luxury Resort on the east coast of Zanzibar, near Uroa, and is open exclusively to hotel guests — there's no day-pass option or walk-in access. The space takes its name from a cave-inspired design, with indoor and outdoor treatment rooms set around a tropical lake.

The menu runs to five treatments, the standout being the Coral Cave Massage, performed inside naturally carved coral formations that are only exposed at low tide along the shoreline. Because it depends on the tide, it's offered at limited times rather than on demand. Couples treatments are also available, either in the spa or privately in-villa.

Beyond the treatment rooms, the property's wellness facilities extend outward: an overwater gym and fitness area overlooking the lake, an overwater yoga patio for private sessions, an outdoor waterfall relaxation area, and a jungle trail for walking or cycling via the resort's bikes and electric scooters. A nail bar and hair styling service round out the offering, along with changing rooms and both indoor and outdoor showers.

Pricing sits at the luxury end of the scale, consistent with the resort's overall positioning, though published hours and per-treatment rates aren't listed — worth confirming directly with the spa before planning a visit.
