Just when they had settled into island life, it was time for Peter and Penny to leave Caye Caulker and set sail for country #20, Mexico. Two bumpy ferry rides and one very queasy tummy later, they disembarked at Chetumal. They’d heard that bus was the way to travel in Mexico, so on they hopped for a much smoother connection to Tulum. First stop was authentic Mexican food and on Tulum’s main thoroughfare they were spoiled for choice. To end a long day, an enchilada and taco stuffed Peter and Penny browsed the colourful wares of the local boutiques. Bright and early the next day, they set out to explore some of the Yucatán Peninsula’s famous Mayan ruins. They were delighted and surprised that they could wander amid the ancient ruins of Coba and even climb the 137-foot Nohoch Mul pyramid. Not wanting to miss such an opportunity and view, Penny had to summon all her courage, and try not to look down, as they navigated the 120 steep, often slippery steps. With time for one more stop, they headed back to see the stunning cliff-top ruins at Tulum. After a short stay in Mexico, the pair agreed that Tulum was among the friendliest and awe-inspiring places they had visited.
