Islands in Zanzibar: Charting Your Multi-Island Course

Ready to explore Zanzibar’s archipelago? Here’s a quick how-to to do it:

1. Base Yourself Strategically:

• Stone Town: Because of its close vicinity, it’s a great place for day visits to Nakupenda Sandbank and Prison Island. Also, a good starting point for Mnemba Atoll tours (though a drive to the northeast coast is required).
• Nungwi/Kendwa (North): Ideal base for Mnemba Atoll snorkelling and diving trips, as many tour operators depart from here.
• Paje/Jambiani (East): Good for reaching the Blue Lagoon/Safari Blue tours.

2. Plan Your Islands in Zanzibar Excursions:

• Prison Island & Nakupenda Sandbank: Easily arranged as half-day or full-day trips from Stone Town by local boat operators (“beach boys” or reputable tour companies). Negotiate prices, or book through your hotel.
• Chumbe Island: Requires booking directly with CHICOP well in advance due to limited accommodation (only 7 bungalows) and their controlled visitor numbers to maintain ecological balance. They provide transport.
• Mnemba Atoll: Numerous dive and snorkel centres along the north and northeast coasts offer daily trips. Shop around for reputable operators with good equipment and safety records.
• The majority of hotels and tour: Companies on the island offer reservations for Kwale Island and Blue Lagoon (Safari Blue). These are full-day excursions that usually include a seafood lunch, many stops, and snorkelling.

3. Combine Experiences for a Richer Trip:

1. History & Nature Mix: Start in Stone Town for historical immersion and Prison Island, then move to a beach area (e.g., Nungwi) for ocean activities like Mnemba Atoll.
2. Eco-Conscious Focus: Dedicate a night or two to Chumbe Island for a unique eco-experience, complementing your main island stay.
3. Adventure & Relaxation: Combine an active day on a Safari Blue tour with quieter beach days or cultural exploration.

4. Practical Considerations:

• Transportation to Excursions: Most tours include boat transport. For land transfers to departure points (e.g., to the Mnemba Atoll boat launch), taxis or dala-dalas (local minibuses) are available.
• Booking: For popular tours (like Mnemba Atoll, Safari Blue) or limited-capacity experiences (Chumbe Island), book a few days in advance, especially during peak season.
• What to Bring: Sunscreen (reef-safe if possible for marine areas), hat, sunglasses, swimwear, towel, dry bag for electronics, water bottle, and cash for small purchases or tips.
• Respect Local Culture: When interacting with local communities on the islands, dress modestly (shoulders and knees covered) out of respect, especially away from tourist-designated beach areas.

Zanzibar’s islands are not just satellite attractions; they are integral to understanding and appreciating the full spectrum of what this unique archipelago offers. They provide the solutions to the typical travel dilemmas, escaping crowds, finding genuine connection with nature and culture, and experiencing truly diverse adventures.
If you’re seeking an island getaway that feels more authentic, more engaging, and more uniquely you, then looking beyond Unguja to the smaller islands of Zanzibar is your next move. It’s time to discover the layers of this incredible destination, one island at a time. Your real island escape awaits.
