Bring motion-sickness medication
The trip spends hours offshore where swell can increase; take seasickness meds at least 30 minutes before departure if you’re prone to motion sickness.
Sun protection matters
Bring a wide-brim hat, high-SPF sunscreen, and polarized sunglasses — reflected sun off the water intensifies UV exposure.
Waterproof camera or dry bag
Waves and spray are common when viewing whales and during the swim stop; protect electronics in a dry bag.
Respect wildlife viewing rules
Keep noise low and follow crew instructions to avoid disturbing whales and dolphins; maintain recommended distances.
Sunscreen (SPF 30+)
