Snorkeling with Whales in Mirissa: Swim with Blue Whales off Sri Lanka
Head out from Mirissa before dawn to search deep offshore waters for blue whales, fin whales and other giants. This four-hour snorkeling tour balances respectful animal interaction with practical safety and local knowledge—ideal for confident swimmers seeking a rare marine encounter.
The Experience
Before You Go
Take seasickness meds ahead of time
The ride to deep water can be choppy; take anti-nausea medication at least 30 minutes before departure if you’re prone to motion sickness.
Use reef-safe sunscreen
Protect your skin and coral by using mineral-based, reef-safe sunscreen and reapplying before the swim.
Secure electronics in waterproof cases
Bring a waterproof camera or case and fasten it to you—waves and sudden movement can easily dislodge gear.
Listen to the crew’s briefing
Crew instructions cover distance rules and entry techniques; following them keeps both you and the animals safe.

Common Questions
How likely am I to see whales?
Sightings are common during peak season (roughly November–April), but not guaranteed; sightings depend on sea conditions, currents and animal movement.
Do I need to be an expert swimmer?

Tours advise against participation for pregnant travelers and those with serious cardiovascular or spinal issues; check with the operator if you have health concerns.
When do tours depart?

What happens if no whales are seen?
Most operators will offer a reschedule or refund option if no whales are located due to conditions—confirm the policy when booking.

Yes; bring or take over-the-counter seasickness medication before departure, stay hydrated, look at the horizon and sit in the boat’s center for a steadier ride.
