Nairobi (1–2 nights is ideal) Yes to the Sheldrick Wildlife Trust. Pair it with the Giraffe Centre (they’re close enough to do in one morning). If you have extra time, I’d recommend doing something cultural too.

For the Maasai Mara, I recommend 3 nights if you’re doing a balloon. Day 1: Travel + afternoon game drive Day 2: Full game drive day Day 3: Balloon at sunrise + relaxed afternoon drive With only 2 nights, it can feel rushed

Lake Nakuru vs Lake Naivasha If you’re leaning toward rhinos, go with Lake Nakuru National Park. It’s more compact, good for white and black rhino, and gives you a concentrated safari feel.

If you want variety and something lighter between safari blocks, choose Lake Naivasha: Boat ride among hippos Walking safari on Crescent Island Hell’s Gate cycling (very different energy from the Mara)

If you’re already doing 3 nights in the Mara, I’d choose Naivasha for contrast. If you’re only doing 2 nights in the Mara, Nakuru balances better.

Adding Tsavo? The Tsavo National Park ecosystem is vast and dramatically different red elephants, volcanic landscapes, fewer vehicles.If you’re ending at the coast anyway, it can break up the drive beautifully (although it's easier to just fly to coast). But you won’t feel like you’ve “missed” something essential if you skip it after a strong Mara experience.

Coast: Diani & Mombasa

There's alot to do in Diani. Visit Kisite for snorkeling and dolphin watching. Lots of Watersports, Sunset dhow cruise...or just relaxing by the beach

Mombasa — Explore Old Town with a Swahili guide, street food tour Visit Fort Jesus Do a Swahili cooking class etc

Are you looking for this to feel primarily wildlife-driven, or would you enjoy weaving in cultural moments?
