If you happen to be planing a vacation to Medellin in Columbia and are interested in eco-tourism or outdoor recreational activities in and around this city of approximately 2.5 million people, here are a few parks, gardens and nature reservses that you might want to visit. First and foremost on my list are Parque Arvi and Piedra Blancas both of which are located in the mountains surrounding the city and easily accessed by the metro cable car systems. The cable car takes you as far as Parque Arvi and a short bus ride of about 5 minutes will take you to Pierda Blancas eco-resort where you will find campgrounds, nature trails, butterfly pavillion, lake, boat rentals, hotel, restaurant and more. Another favorite getaway for tourist is Guatape approximately one hour away from the city by bus. It features a lake with islands, windsurfing, boat tours and a large monolith with a unique observation deck that is reached by climbing a built in staircase of 750 steps. Perhaps the most often visited location in central Medellin for tourist and locals alike is Cerro Nutibarra, a nature reserve in the mountains overlooking the city and reached by a city tour bus. It offers guided nature trails, art nature trails, bird watching, outdoor amphitheater for concerts, musuem, restaurants and a replica of what mountain villages around Medellin where like in the past.. The Uribe Botanical garden is another popular attraction for the eco-tourist. It features a variety of gardens, trails, lagoon, restaurant and is next door to parque explora as well as the city planetarium. Other photos included in this gallery are barefoot park behind the convention center, El Castillo Musuem and Gardens, as well as an example of floral arrangements seen at the annual festival of flowers.
