Watamu Marine National Park — 10 sq km of protected coral reef on Kenya’s north coast, 105 km south of Malindi and 20 km north of Malindi Airport — is the oldest marine park in East Africa (established 1968) and one of its most ecologically intact: the coral garden reefs of Watamu (particularly the Channel Reef, the northern reef system, and the Whale Island coral formations) have been consistently protected from net fishing for 55+ years, producing a reef environment with dramatically higher coral cover and fish biomass than the unprotected reef sections of the wider Malindi-Watamu coastline. The park’s additional value: a reliable whale shark aggregation season (October–February, when juvenile whale sharks follow the plankton blooms concentrated by the monsoon transition in the Watamu Channel) and the green and hawksbill sea turtle nesting programme (the longest continuous marine turtle research programme in Africa, run by the Local Ocean Trust since 1997). This guide covers Watamu Marine Park for 2025.
Snorkelling and Diving
Watamu’s coral reefs are accessible by the boat trips that operate from the Watamu village beach (a 10-minute motorboat ride to the Channel Reef or Whale Island). Snorkelling: the standard activity — most visitors snorkel rather than dive, as the reef-top shallows (2–5 m depth) have exceptional coral garden quality with green turtles commonly resting and feeding on the reef. A green turtle (Chelonia mydas) sighting at Watamu is extremely reliable — the park’s turtle population (estimated 150–200 resident green turtles, with significant hawksbill presence) makes Watamu Kenya’s best turtle snorkelling destination. Boat trip cost: KSh 2,000–3,000 per person (approximately USD $15–24) for a 2-hour snorkelling trip including park entry. Diving: Aqua Ventures (the park’s principal dive operator, PADI 5-star) offers dives at USD $50–70/dive on the wall sections of the park where the reef drops to 20–30 m depth. The deeper sections produce eagle rays, reef sharks (reef whitetip and reef blacktip), moray eels, and the occasional manta ray.
Whale Shark Season
The whale shark (Rhincodon typus — the world’s largest fish, reaching 12–15 m length) aggregates in the Watamu Channel area from October to February, drawn by the plankton blooms that the southeast-to-northeast monsoon transition produces in the shallow coastal waters. The Watamu whale shark programme (Local Ocean Trust manages the research and sustainable tourism): whale shark snorkelling trips (NOT diving — whale shark interaction rules require snorkel surface swimming, not underwater approach) operate from Watamu village when a shark is reported, departing immediately on sighting. The boat follows the shark at 30 m distance, dropping snorkellers 15 m ahead of the shark’s direction of travel — the whale shark approaches and passes at 1–3 m distance from the snorkellers. Cost: USD $60–80/person for a 3-hour whale shark trip. Success rate when whale sharks are in season: approximately 70% on any given October-February day.
