Yes. Chanchamayo is considered Peru's coffee heartland, and several working haciendas near San Ramón welcome visitors for a walk through the plantation, a look at how beans are processed, and a fresh cup at the end. A coffee stop pairs easily with a waterfall visit in the same day.
San Ramón sits about 303 km (188 miles) northeast of Lima. A private transfer typically takes 6-8 hours depending on traffic and any stops you add along the way; buses and colectivos cover the same route in roughly 7-9 hours, schedules permitting.
Many travelers do. Tarma, known for its flower gardens and colonial center, lies on the way down from the highlands, while La Merced, San Ramón's jungle neighbor, is just 12 km (7 miles) further with its own market and plaza. Since the transfer is private, you can build in a stop at either town without arranging a separate trip.
The Chanchamayo valley around San Ramón has several jungle waterfalls worth the detour. Bayoz Falls drops about 60 meters through dense forest, Velo de la Novia (Bride's Veil) cascades roughly 55 meters, and Tirol Falls is a smaller, easy 30-meter cascade with a pool at the base for swimming. Most day-trippers pick two or three to visit.
The route is part of the experience. After crossing the high Andes, the road descends more than 2000 meters over a few dozen kilometers, dropping from cold mountain passes into warm, humid jungle within a couple of hours. Watch the scenery shift from grassy highlands to cloud forest to tropical vegetation — one of the most dramatic landscape changes you can see near Lima in a single day.
San Ramón is the gateway to Peru's central jungle, where the Andes drop straight into rainforest. In a single day you can walk through cloud forest, hike to jungle waterfalls, and sample coffee grown minutes from town — a landscape completely different from Lima's coast, reached in one journey.
