Most tours welcome all ages, but some operators may have age restrictions due to boat size or trip length. If traveling with young children, check age policies before booking. Motion sickness can be a concern, so consider shorter tours or bringing seasickness remedies for a smoother experience.

Dress in layers—it’s always cooler on the water. Bring sunscreen, sunglasses, and a hat for sun protection. Binoculars enhance wildlife viewing, and motion sickness remedies can help if you're sensitive to rough seas. A camera is a must, but be ready to put it down and enjoy the moment.
