Grand Cayman - Bioluminescent Bay Tour

This evening boat tour runs about 3 hours and 15 minutes and is a relaxed way to see two very different sides of Grand Cayman after the sun sets. It’s not rushed, and it’s not loud. The focus is on being out on the water, seeing a few special places, and taking your time with them.

You’ll start at the marina in George Town and head out by boat as daylight fades. The ride itself is calm, with coastal views and a chance to settle in before the first stop. Starfish Point is where you’ll spend the sunset. The water here is shallow, and you can step onto the beach or stay on the boat if you prefer. Most people take photos, look for starfish in the clear water, and just enjoy the quiet. You’re welcome to bring your own snacks or drinks, which makes this stop feel casual and unstructured in a good way.

Once it’s dark, the boat continues on to Bioluminescent Bay. Before anyone gets in the water, the guide explains what causes the glow and what to look for. Then, with a snorkel mask and life vest provided, you can swim or snorkel at your own pace. As you move, the water lights up around you. It’s subtle but noticeable, especially when you slow down and let your eyes adjust.

After time in the bay, you’ll dry off and head back to the marina. The ride back is easy and quiet, and you finish right where you started, having seen something that most daytime tours miss.
