In the company of a private guide, visit the ruins of Altun Ha, go tubing through a rich cave system, and breeze through the air on a spectacular zipline course on this day trip. After getting picked up from Belize in the morning, head to the ancient Mayan city of Altun Ha. Here, enjoy a guided tour of the pyramids, walkways, and plazas as you learn about the site's history dating back to the 10th century BC.

Next, head to a zipline course built in the canopy of Belize's lush rainforest. Gear up and strap in for a ride that takes you over the treetops. Reach heights of 85 feet above the ground for terrific views of the jungle rushing below.

Grab some lunch and catch your breath ahead of an expedition that takes you into the rainforest and to the mouth of a system of caverns fed by the Caves Branch River. Here, pick up your tubing gear and set off to let the current carry you underground. Admire stone pillars, stalactites, and stalagmites, and learn how the Mayans viewed these surroundings as a part of the underworld before the tour wraps up with a ride back to Belize.
