As the sun starts to dip, you’ll enjoy the spectacular sunset—a favorite moment for many, with viewers describing it as “beautiful” and “peaceful.” The guide’s commentary enhances this, offering star-gazing tips and local lore.
Once the sun sets, the real magic begins.

Swimming and Additional Activities
After the paddle, many groups pull onto a small island or beach to enjoy snacks and swimming.
