To register, please call us at 207-370-9044 during the day or early evening. Please leave us a message if we’re out on an adventure and not answering! The earlier you call us with your interests, the better chance we’ll have of securing your desired date. If we’re on another line or out on an adventure, we will return your call. Group size is limited to 6 passengers. If your plans are last minute, try us anyhow, you never know. To secure your reservation, Casco Bay Adventures may require $100 deposit payment by cash, check or credit card.


For our adventures, you may be required to sign a Waiver of Liability and Release before embarking on your adventure. In addition, participants younger than 18 not accompanied by a parent or guardian will be required to have a signed release form from a parent/guardian.

What to bring…

While Maine summers can be warm and bright, the weather on the bay is often much cooler than it is in Portland. For all adventures, it is best to bring a sweatshirt or light jacket, sunscreen, hat, sunglasses, possibly a rain coat, a camera and, if you desire, binoculars. If you are planning an overnight adventure, pack sleeping bag and pillow. For fishing adventures, you can either bring your own gear or use the rods and lures provided by CBA.
