The Best Day Trips from Stone Town, Zanzibar, Ranked

Stone Town is Zanzibar's gravitational centre, and it deserves two unhurried days of its own: the alleyways, the carved doors, the long evening at Forodhani Gardens. But the island's best days happen elsewhere — on reefs, in forests, on plantations and on sand that exists only at low tide. Base yourself in or near the old town, agree the transport and the fees before you set off, and work through these in roughly this order.

Two things have changed since most guides to this subject were written, and both are about money. Zanzibar revised its entry fees for marine conservation areas with effect from September 2025, and mandatory inbound travel insurance has applied to foreign visitors since October 2024. Neither is ruinous. Both turn up as surprises at the wrong moment if nobody has told you.

Before you book: the tide, the season and the fees

Three things decide whether a Zanzibar day trip works, and none of them is which operator you pick.

The tide. This island runs on it. On the east coast the sea walks out several hundred metres and sometimes close to a kilometre, leaving seagrass flats you cannot swim in; at the northern tip it barely retreats at all. Sandbanks surface and vanish within a single day. The Rock restaurant is a walk across sand at low water and a boat ride at high. Any operator worth paying reads a tide table as a matter of routine — ask them to tell you which tide your day is built around, and if they cannot answer, book with someone else.

The season. Two monsoons govern the year. Kaskazi, roughly December to February, brings warmer and calmer water, the better swimming, and the wind that pushes seaweed onto the east-coast beaches. Kusi, roughly June to October, is drier and breezier, with cleaner water on the east coast and the kitesurfing season at Paje. The long rains fall around March to May, and that is the window to avoid: rough seas, cancelled boats, and businesses that simply shut — Chumbe Island, below, closes for annual maintenance for around six weeks in that period.

The fees. Almost everything here carries a government charge sitting on top of the operator's price, and the single most common dispute on the beach is whether the quote included it. Ask the question in those words. Since the September 2025 revision, entry to the marine conservation areas typically runs around USD 10 per adult for non-East African visitors, with roughly half that for children and free entry for the very young. The compulsory inbound insurance, sold through the Zanzibar Insurance Corporation, costs about USD 44 per adult and around half that for children, and is normally arranged before you fly.

Getting around. Taxis are unmetered; agree the fare before you get in, and expect a half-day with a driver to come to something in the region of USD 40 to USD 70 depending on distance and your negotiating. Dala-dalas — shared minibuses — leave from around the Darajani market area, cost very little, and are slow, crowded and genuinely useful if you have the whole day and no fixed return. Most of the trips below are sold with transfers included, which is usually the better value once you have priced the alternative.

Where to sleep. Shangani, on the western seafront, holds most of the characterful hotels and is the quietest corner of the old town. Kiponda and Mkunazini, deeper in the maze, have the cheaper guesthouses. Malindi sits to the north, nearest the port. Anywhere in the old town puts you within about fifteen minutes on foot of the seafront where the boats leave.

One more thing to check: Ramadan moves about eleven days earlier each year, and during it many Stone Town restaurants close in daylight hours. It is a rewarding time to be here, but not a spontaneous one.

1. Prison Island (Changuu)

A short crossing offshore, and the easiest big reward on the island. The name misleads: holding cells were built here in the 1890s under Sultan Barghash, but the island was never used as a prison in the way the name suggests, serving instead as a quarantine station for yellow fever from the 1920s. What people come for now is the colony of Aldabra giant tortoises, a gift from the Seychelles around a century ago, the oldest of which are said to be well over a hundred years old. The keepers hand you spinach leaves; the tortoises are entirely unbothered by you.

Boats leave from the seafront below Shangani and Forodhani and take roughly twenty to thirty minutes each way. Island entry is charged separately from the boat, and the figure has moved more than once in recent years — budget somewhere around USD 5 to USD 10 per person and carry more than you expect to need, in small notes. Two to three hours on the island is plenty. The snorkelling off the beach is decent rather than spectacular, and the old cells take about ten minutes. Go in the morning, before the crossing gets choppy and the island gets busy.

2. Jozani Chwaka Bay National Park

Zanzibar's only national park, and the reliable place to see the Zanzibar red colobus, a monkey found nowhere else on earth. Guided walks take you through groundwater mahogany forest and out along a raised boardwalk over the mangroves, which is the better half and the part people rush.

Entry runs to around USD 12 per person and typically includes an official ranger guide — you do not walk it alone. The park generally opens around half past seven in the morning and closes around five, and the timing genuinely matters: arrive at opening and the colobus are awake, feeding, and moving through the low branches within a few metres of the path. By late morning they are asleep high in the canopy and the coach parties have arrived. Keep roughly three metres back, which is the park's own rule and exists because we and they share diseases.

It sits around forty-five minutes to an hour from Stone Town on the road to the east coast, which is the whole argument for pairing it with Paje, Jambiani or lunch at The Rock in a single day.

3. A spice farm, and the Persian baths next door

Zanzibar was the Spice Island, and the plantations north and north-east of Stone Town still grow cloves, nutmeg, cinnamon, cardamom, black pepper and vanilla. Kizimbani is the government-run farm and feels institutional in a way that suits some visitors and bores others. Tangawizi — the Swahili word for ginger — is privately run and draws more consistent praise for its tastings and its guides. Kidichi is the one to choose if you want the Persian baths built around 1850 by Sultan Seyyid Said for his Persian wife, which are a genuine piece of history sitting incongruously among the vanilla vines.

Expect to pay somewhere around USD 15 to USD 30 per person from Stone Town, depending on whether transfers are included, and reckon on about two to three hours. What separates an absorbing morning from a shopping stop is entirely the guide, so ask for a named one and tip properly. Cloves and vanilla are worth buying at source; the bottled spice oils sold as remedies are not.

This pairs naturally with Prison Island, the farm in the morning and the boat after lunch, or the reverse.

4. The Nakupenda sandbank

A strip of white sand that surfaces off Stone Town as the tide drops and is underwater again by evening. Boats leave in the morning, a grilled seafood lunch comes with them, and the whole thing lives or dies on the tide table — which is why you book it through someone who reads one properly rather than whoever approaches you on the seafront. Expect around USD 35 to USD 60 per person on a shared boat, and considerably more privately; the nature reserve fee is often charged on top. There is no shade out there at all. Bring your own, or accept that you will be renting an umbrella at whatever the going rate turns out to be that morning.

If you would rather have one long day on the water than a short one, consider Safari Blue instead. It leaves from the Fumba peninsula, roughly forty-five minutes south of Stone Town, and runs through the Menai Bay Conservation Area: traditional dhow sailing, a mangrove lagoon, snorkelling stops, a sandbank and a Swahili seafood barbecue on Kwale island. It is typically a pickup around eight in the morning and a return by late afternoon, and costs somewhere in the region of USD 60 to USD 120 depending on the operator and what is bundled in. Nakupenda is the shorter, cheaper, closer option; Safari Blue is the fuller day.

5. Mnemba reef

The reef ringing a small private island off the north-east coast, and the snorkelling and diving most visitors come to Zanzibar hoping for. Snorkeling Report, a specialist site, rates the atoll as having the best reef condition and the highest marine biodiversity in the Zanzibar archipelago. In practice that means hawksbill turtles fairly reliably, dense reef fish, harmless whitetip reef sharks, and a decent chance of bottlenose or spinner dolphins on the ride out.

You cannot land on Mnemba itself — the island is leased and private — so this is a water trip, not a beach one. The marine conservation area fee of around USD 10 per adult for non-East African visitors applies here and should be confirmed as included or not before you pay anything. Boats run roughly fifteen to twenty minutes from Matemwe on the east coast, or around thirty to forty-five minutes from Nungwi and Kendwa in the north.

From Stone Town you are looking at an hour and a half on the road before you even reach the boat, which is the argument for sleeping a night or two up north or at Matemwe rather than attempting it as a day return. Go early: calmest water, fewest boats.

6. Nungwi and Kendwa

The north tip, where the tide barely retreats and you can swim at any hour — the thing the east coast cannot offer. Nungwi is the larger, busier village, with a working beach where dhows are still built by hand; Kendwa is quieter sand a short walk or boat hop to the south, and the site of the monthly full-moon party at Kendwa Rocks. Sunset dhow cruises leave from both, typically costing around USD 25 to USD 40 per person, and the sunsets do deserve the cliché.

The Mnarani Marine Turtles Conservation Pond sits near the Nungwi lighthouse: a large natural tidal pool in the coral rock, holding green turtles, with entry around USD 10 that usually includes a guide and seaweed to feed them. An honest note, because the reviews divide sharply — it is a rehabilitation pond rather than open sea, and visitors disagree about whether what they are looking at is conservation or captivity. Look at it and decide before you buy the ticket.

Reckon on an hour to an hour and a half from Stone Town by road.

7. The east coast and The Rock

Michamvi and Pingwe sit on the east side, roughly sixty kilometres south-east of Stone Town and about an hour and a half by road. The Rock is the image the island sells itself with: fourteen tables on a weathered coral outcrop in the tidal zone, reached on foot across the sand at low water and by a very short boat ride at high. It opens daily for lunch and dinner and typically closes in the early evening. Reservations are obligatory and should be made well ahead in high season.

Expect a bill well above the island average. You are paying for the setting, the setting is worth it, and the seafood is good rather than transcendent — go knowing that and you will enjoy it. Book lunch on a falling tide if you want to walk out to it, which is the better arrival.

While you are on that coast: Paje is the kitesurfing village and busiest of the three, Jambiani is the quieter one where people actually live, and Kuza Cave near Jambiani is a freshwater pool inside a limestone cavern, run as a cultural centre, with a small entry fee and the option to swim. Jozani is on the same road, so the sensible shape of this day is the forest at opening, lunch on the rock, and the afternoon on a beach.

8. Chumbe Island Coral Park, if you can get a place

A fully protected reef sanctuary and forest reserve off the west coast, funded entirely by its own ecotourism income. Day visitors get a guided snorkel over reef that has been protected for decades and shows it, forest and mangrove walks, the old lighthouse and visitor centre, and lunch with drinks. Expect somewhere around USD 90 per day guest, plus a Blue Economy levy of roughly USD 25 for adult foreigners charged on top.

The reason it sits at eight rather than considerably higher is access, not quality. Day places only exist when the small eco-lodge has room, bookings are generally only taken around four days in advance, and the island closes for annual maintenance for about six weeks across April and May. Ask on your first day in Stone Town, be ready to go at short notice, and treat it as a bonus rather than a plan.

What to skip, and why

Swimming with dolphins at Kizimkazi. The problem is well documented by the conservation organisations working in Menai Bay: boats chase pods, encircle them and drive across them, and swimmers are dropped in on top of animals whose hearing is far more sensitive than ours. Groups monitoring the bay report the dolphins surfacing less and moving further from their gathering grounds as a result. If you still want to go, the distinction that matters is operator training — a small number run trips with skippers trained through a local conservation programme, who keep their distance and do not pursue. Booking the cheapest boat offered to you on the sand guarantees the other kind.

Also decline the day billed as Jozani plus The Rock plus Nungwi. It is sold, it is possible, and it puts you in a minibus for something like five hours to stand in three places for forty minutes each.

Putting it together

With four days: spice farm in the morning and Prison Island after lunch on the first; a full day on the water on the second, Nakupenda if you want it short and Safari Blue if you want it long; Jozani at opening, lunch at The Rock and an afternoon on the east coast on the third; then move north and take the Mnemba boat early the following morning from Nungwi or Matemwe.

With two: Jozani and The Rock in one day, since they share a road, and Prison Island with the sandbank in the other, since they share a tide.

Tip: Zanzibar is predominantly Muslim, and Stone Town is not a beach town. Cover shoulders and knees away from the resorts — it is a small courtesy that changes how the island receives you.
