The decks of the vessels are multi levels and can be slippery when wet. Passengers must have good mobility to safely move around the vessels, step onto the glass bottom boats (if applicable) and get in and out of the water via the ladders on the back of the vessels. Unfortunately, we do not offer wheelchair access due to the layout of the decks and saloon areas. Our tours are adventure experiences for active travellers.
