Sanctum Una Una Eco Dive Resort

Sanctum Una Una is the best-reviewed dive operation in the Togean archipelago (Tripadvisor 4.6 across roughly 290 reviews, and low-9s scores on booking platforms), run by French instructor Cedrick Lievre and his largely local team on the shore of volcanic Una Una. The diving is the reason most people come: walls and pinnacles shaped by the Colo volcano, schooling barracuda, and house-reef coral restoration run with Ocean Quest Global. Courses run year-round under SSI and ADIP, with PADI certification available on request; fun dives start at Rp 575,000–650,000 each depending on volume. The resort itself has outgrown its budget-shack origins. Six room categories run from simple fan-cooled Garden Rooms (from Rp 350,000) through air-conditioned sea-view rooms to an Ocean Suite and a two-bedroom Family Cottage (from Rp 2,000,000), and the grounds now include an infinity pool, a gym, a yoga area, Starlink Wi-Fi around the lounge and pool, and 24/7 solar power. Meals are no longer compulsory: the optional Sanctum Board package (Rp 320,000 per person per day) covers four daily meals plus gym access and rental equipment, or you can pay per meal. Divers get an accommodation discount (code DIVER30) if they average a dive a day. Book direct via sanctumdiveunauna.com or WhatsApp — the resort arranges the private boat transfer from Wakai, or a faster ~5-hour car-plus-speedboat route from Gorontalo or Luwuk airports.
