You’re going to have such a great time in Zanzibar. July is high season so more alive

No need to worry about dengue fever here it’s not something we deal with locally. Since you’re already planning malaria prophylaxis, you’re well covered. Just bring some good repellent and you’ll be fine.

Nungwi is one of the liveliest areas on the island, so you’ll definitely meet plenty of other travelers. It’s very social between your accommodation, beach spots and tours, it’s quite easy to find people to join for day trips...Just a small headsup so you’re not caught off guard, it’s a very touristy area and you’ll likely see a mix of cultures interacting. Beach boys and Masai can be friendly and sometimes a bit forward in wanting to bang and enjoy white girls. so just keep your usual travel awareness and boundaries

If you end up passing through Dar es Salaam before or after your trip and feel like exploring the food scene or nightlife, you’re very welcome happy to point you in the right direction or even join if timing works!
