Onsea House

A small, welcoming guest house near Arusha, where you can relax before or after a northern circuit safari. If you like tranquil settings, good service, and really really good food, we’d choose Onsea or its neighbouring-property, Machweo.

A 10-minute drive from the busy town of Arusha, Onsea House has a pleasantly relaxed atmosphere, and is a great place to unwind at the beginning or end of a safari in the northern circuit. The main building dates back to the colonial era and is surrounded by well-maintained, long established gardens which provide welcome tranquillity.

The versatile accommodation includes twin, double and interconnecting rooms, some in a self-contained cottage, and a 3-bedroom family suite. The African décor and thoughtful inclusions such as fresh flowers, bathrobes and minibar add a homely feel.

Socialise with other guests in the lounge, cocktail bar and on the terrace, the perfect spot to watch the sunset over the Meru Valley.  You won’t want to miss mealtimes; Onsea House has built a reputation for its fine cuisine and benefits from the skills of a Michelin-experienced chef.

This is most definitely a favourite of ours. It’s not over the top luxury, it’s homely, but in a simple stylish way.

Why Go?

You can easily spend a couple of days at Onsea House and during this time you can enjoy a trip into Arusha National Park which is only half an hour away or spend time exploring the grounds and the forest beyond.  Horse riding is also possible by special arrangement and finally guided tours of the local coffee plantations nearby. Onsea House and the surrounding areas are particularly noted for birding
