Zanzibar Hidden Gems: 5 Places Beyond the Tourist Trail
Most visitors to Zanzibar spend their time in Stone Town and on the main beaches — Nungwi, Kendwa, Paje. These are all worth visiting. But the archipelago holds quieter, deeper experiences that most travellers never discover — a prison island turned tortoise sanctuary, a coral park with the best reef in East Africa, and Persian baths hidden in a clove plantation.
These five hidden gems take you beyond the standard Zanzibar itinerary. None are crowded. Several require deliberate effort to reach. All reveal layers of the island that the beach-and-Stone-Town circuit misses entirely.
1. Changuu (Prison Island) & Its Tortoises
Changuu Island sits 5.6 kilometres off Stone Town's waterfront — a 25-minute boat ride from the harbour. The island was originally used as a holding pen for enslaved people awaiting sale in Stone Town's slave market. In the 1890s, the British colonial government converted it into a quarantine station (hence "Prison Island," though it was never actually a prison).
Today, the island's main attraction is its colony of Aldabra giant tortoises. The original tortoises were a gift from the British governor of Seychelles in 1919. The colony has grown to roughly 100 animals, some estimated to be over 190 years old. They roam freely in a walled enclosure and are accustomed to human visitors — you can feed them by hand and photograph them at close range. The oldest individuals weigh over 200 kilograms.
Beyond the tortoises, Changuu has a small beach with decent snorkeling on the western side, and the ruins of the quarantine buildings are atmospheric and largely unexplored. Entry to the island costs TZS 10,000 ($4). Boat hire from Stone Town runs TZS 15,000-25,000 ($6-10) per person return in a shared boat, or TZS 80,000-120,000 ($32-48) for a private boat. The trip combines well with a morning snorkeling stop — bring your own gear or rent from the boat operator for TZS 5,000 ($2).
2. Matemwe Beach: The Quiet Alternative
Nungwi and Kendwa get the crowds. Paje gets the kitesurfers. Matemwe, on the northeast coast, gets almost nobody. This is Zanzibar's quietest stretch of prime coastline — a long, wide beach of white sand backed by coconut palms, with a handful of small guesthouses and no nightlife whatsoever.
The beach faces Mnemba Atoll, which means the snorkeling is excellent directly from shore at high tide. The reef starts roughly 100 metres out and the water clarity rivals the boat trips. At low tide, the ocean retreats dramatically, exposing tidal pools where local women harvest seaweed — an important livelihood on the east coast. Watching the seaweed farmers work the tidal flats at dawn is one of Zanzibar's most quietly beautiful sights.
Matemwe is 55 kilometres northeast of Stone Town. A dala dala costs TZS 3,000-4,000 ($1.20-1.60) and takes 90 minutes. Budget guesthouses cost $25-40 per night — less than comparable rooms in Nungwi or Paje. The village has a few small restaurants serving fresh fish and Swahili dishes for TZS 5,000-10,000 ($2-4). There is no ATM in Matemwe — bring enough cash from Stone Town. Come here when you want silence, empty sand, and the sound of waves without a bar soundtrack.
3. Chumbe Island Coral Park
Chumbe Island is a privately managed marine sanctuary 12 kilometres south of Stone Town. The coral reef surrounding the island is the best-preserved in Tanzania — possibly in all of East Africa. The island has been a protected area since 1994, and the reef has recovered to a condition rare in the western Indian Ocean. Over 200 species of hard coral and 450 species of fish have been recorded.
The snorkeling is extraordinary. You wade in from the beach and within 30 metres you are over pristine reef with visibility exceeding 20 metres. Parrotfish, butterflyfish, groupers, octopus, and green turtles are regular sightings. The island also hosts a nature trail through coral-rag forest where coconut crabs (the world's largest land arthropod) emerge at dusk.
Chumbe operates as an eco-lodge with seven bungalows built from sustainable materials, powered by solar, and collecting their own rainwater. Day trips cost $90-100 per person including boat transfer, guided snorkeling, forest walk, and a full seafood lunch. Full-day visits run 9:30 AM to 5:00 PM. The price is steep for Zanzibar standards but the reef quality is unmatched. Book through the Chumbe Island website — trips run Tuesday through Sunday with limited capacity.
4. Kidichi Persian Baths
Hidden in a clove plantation 15 kilometres north of Stone Town, the Kidichi Persian Baths are a relic of Zanzibar's Omani Arab period that almost nobody visits. Built in 1850 by Sultan Seyyid Said for his Persian wife, Princess Scheherazade (yes, really), the baths feature intricate stucco decorations — geometric patterns, floral motifs, and arabesques carved into the domed ceilings and walls.
The baths are no longer functional but the architecture is remarkably intact. The main bathing chamber has a vaulted ceiling with decorative recesses, and the surrounding rooms include changing areas and rest chambers. The stucco work is Persian in style — the craftsmen were brought from Shiraz specifically for this project. The effect is a small piece of Iran transplanted into a tropical clove forest.
Entry costs TZS 5,000 ($2). There is rarely a guide on site — you explore independently. The baths are on the road to Mangapwani, reachable by dala dala (TZS 1,500 / $0.60) or taxi (TZS 15,000-20,000 / $6-8). Combine the visit with a walk through the surrounding clove plantations — the smell during harvest season (July-October) is intoxicating. Allow 30-45 minutes for the baths themselves.
5. Mtoni Palace Ruins
Mtoni Palace was the oldest palace on Zanzibar, built in the 1820s for Sultan Seyyid Said — the same ruler who built the Kidichi baths. At its peak, the palace housed the Sultan's household of over 1,000 people, including his wives, children, concubines, and servants. Princess Salme (later Emily Ruete), who wrote the first autobiography by an Arab woman, was born here in 1844.
Today, Mtoni is a romantic ruin. The roofless walls, crumbling arches, and overgrown courtyards are atmospheric and largely unvisited. The remains of the bathhouse, the main residence, and the courtyard where Persian peacocks once roamed are all identifiable. A few information boards explain the history, but the site is best visited with a guide who can bring the palace's extraordinary story to life.
Mtoni is 7 kilometres north of Stone Town on the coast road. A dala dala costs TZS 500 ($0.20), or walk along the coastal road in about 40 minutes. Entry is free, though a caretaker may ask for a small donation (TZS 2,000-5,000 / $0.80-2). The palace overlooks the sea, and visiting at sunset — when the light filters through the empty doorframes and the Indian Ocean glows orange — is one of Zanzibar's most evocative moments.
Combine Mtoni with the nearby Maruhubi Palace ruins (2 kilometres south, also free) — another of Sultan Barghash's constructions. The Maruhubi baths with their Persian-style columns reflected in a pool of still water are particularly photogenic. Together, the two palaces take 2-3 hours and cost virtually nothing.
Zanzibar's hidden gems reveal the island's depth. A tortoise colony on a former quarantine station. A beach where the only sound is waves. A coral reef so protected it looks like a museum exhibit. Persian baths in a clove forest. A ruined palace where an Arab princess wrote her memoirs. These are not alternatives to Stone Town and the beaches — they are the reason Zanzibar stays with you long after you leave.
