Take the kids landsailing with Aruba Active Vacations. Here's how they describe the sailing:
Landsailing craft can move much faster than the current wind. Aruba is great for landsailing – as we have wind most of the time, and there are many flat sandy areas around the island to practice.
It is quite easy to learn the basics. You practice for a while with you instructor, but by the end you can race around the land powered by the wind.
Our landsailing tour is 2 hours and includes instruction, safety gear, a water bottle, with pick up and drop off at your hotel (for the main hotel strip). We advise you to bring sport shoes or trainers, sunscreen, sunglasses for the flying sand and dust, and clothes you don’t mind getting dusty.
This will be an unforgettable experience for the kids. Bring your GoPro if you have one with a mount.
