Tucked away just a few minutes from Nairobi’s bustling city center lies one of its most peaceful sanctuaries — the Nairobi Arboretum. This lush green oasis is where city dwellers come to breathe, jog, meditate, and reconnect with nature. With over 350 species of indigenous and exotic trees, a vibrant bird population, and scenic walking trails, the Arboretum stands as Nairobi’s living museum of trees — a reminder that even in a fast-growing metropolis, nature still has a home.
Where Is the Nairobi Arboretum Located?
The Nairobi Arboretum is located along State House Road, about 3 km from the Central Business District, and sits between Uhuru Highway and Kileleshwa. It’s adjacent to State House and St. Mary’s School, easily accessible by car, matatu, or even on foot from areas like Yaya Centre or Westlands.
A Living History of Trees
The Arboretum was established in 1907 by Mr. Batiscombe, then the Deputy Conservator of Forests in Kenya’s colonial administration. His goal was to plant fast-growing species that could provide fuelwood for the expanding railway and settlements.
Over a century later, what began as an experimental plantation has evolved into a thriving urban forest covering 30 hectares (74 acres). The trees, once tested for utility, now serve a higher purpose — preserving biodiversity and offering respite for thousands of visitors each month.
A Walk Through Nature
The moment you step through the gates, the noise of Nairobi fades away. The tree canopy closes in, and the air turns cool and clean. Winding paths lead through groves of eucalyptus, jacaranda, croton, fig, and olive trees, each labeled for education and conservation.
The Arboretum’s walking trails total more than 3 kilometers, popular with joggers and families alike. Birds flit through the branches, and butterflies dance across shafts of sunlight. On weekends, the lawns are dotted with yoga enthusiasts, students sketching, and couples picnicking under the shade.
It’s not unusual to find a choir rehearsing or a local artist painting amidst the trees — proof that the Arboretum is not just a park, but a creative and spiritual space.
Biodiversity Highlights
The Nairobi Arboretum is home to:
350+ tree species, both indigenous and exotic
Over 100 species of birds, including speckled mousebirds, hornbills, and sunbirds
Sykes’ monkeys, which are friendly but known to steal food from picnickers
A rich undergrowth of ferns, shrubs, and flowering plants
Some of the notable trees include the giant baobab, candelabra cactus, and bamboo stands from Asia. During the flowering season, the purple blossoms of jacarandas create a dreamy carpet that transforms the park into a photographer’s paradise.
What to Do at the Nairobi Arboretum
1. Walking and Jogging
The Arboretum’s shaded trails are ideal for morning or evening walks. Locals often use it for fitness runs, and it’s a favorite spot for the Nairobi Hash House Harriers and weekend wellness groups.
2. Photography and Picnics
From engagement shoots to family outings, the park’s natural beauty provides endless backdrops. There’s a small entrance fee for professional photography, but the stunning scenery — flowering trees, rustic benches, and winding paths — makes it worthwhile.
3. Birdwatching
Bring binoculars and patience, and you’ll spot dozens of resident and migratory birds. Early mornings are best, when the park is quiet and birds are most active.
4. Yoga and Meditation
Several yoga and meditation communities hold outdoor sessions under the trees. The cool breeze, birdsong, and rustling leaves make it an ideal environment for mindfulness.
5. Community and Cultural Events
The Arboretum occasionally hosts cultural performances, nature walks, and environmental awareness programs organized by the Friends of Nairobi Arboretum (FONA) — a volunteer group that works to maintain and protect the park.
Friends of Nairobi Arboretum (FONA)
Established in 1996, FONA partners with the Kenya Forest Service (KFS) to care for and restore the Arboretum. Their work includes tree planting, clean-up drives, and educational programs for schoolchildren. Visitors can support their efforts through donations or by joining volunteer tree-planting sessions held throughout the year.
The Experience: Peace Within the City
What makes the Nairobi Arboretum truly special is its balance — it’s both a wilderness escape and a community space. On a weekday morning, you’ll find the park tranquil, with soft sunlight filtering through trees. On weekends, it comes alive with laughter, music, and families enjoying picnics.
Whether you come to exercise, reflect, or simply rest, the Arboretum has a way of slowing time. It reminds visitors that Nairobi — often called “The Green City in the Sun” — still lives up to its name.
When to Visit
The Arboretum is open daily from 6 AM – 6 PM. The best time to visit is during the dry months (June–September and December–February), when paths are dry and flowers bloom.
During the rainy seasons (March–May and October–November), the park becomes lush and misty, though some trails can be muddy — perfect for photographers seeking dramatic greenery.
