I did the TMB guided trek in early July and it was an unforgettable experience. The scenery was stunning —snow capped mountains, lush green meadows, wildflowers, rivers, alpine lakes with mirror-like reflections, and the sound of cowbells all around to keep us company. Our guide, Alfonso, was exceptional: knowledgeable, supportive, and incredibly thoughtful. He motivated me through tough descents, helped with my luggage when I was struggling with elbow pain, and even arranged special lunches for my diet needs. His encouragement made a huge difference. The trek is challenging with steep ascents and descents, especially some portions with rocky terrain but the sense of accomplishment each day is priceless. Overall great food, excellent hotels, and efficient communication through emails by Salamander adventures company — highly recommended! A couple of suggestions would be: Two guides would be better than one and though a celebratory wine was good at the end, a medal or certificate to each finisher would be a great souvenir to cherish. Overall, an excellent company that cares and I look forward to doing more treks with them in future.
