The rain forest that covers most of Cerro Ancón is a remarkably vibrant natural oasis in the midst of the city. The best area to see wildlife is on the road to the Cerro Ancón Summit, which is topped by radio towers and a giant Panamanian flag. The road ascends the hill's western slope from the luxuriant residential neighborhood of Quarry Heights, above Balboa. There is also a trail into the forest behind the offices of ANCON, Panama's biggest environmental group. If the gate at the end of Quarry Heights is locked, it should take 20-30 minutes to hike to the summit. It is best done early in the morning or late in the afternoon, when you are likely to see animals such as the abundant agoutis (large rodents), keel-billed toucan and Geoffrey's tamarind—Panama's smallest simian. If you have a taxi drop you off at the trailhead (ask the driver to take you to the "Oficinas de ANCON" in Quarry Heights), you can hike down the other side of the hill to Mi Pueblito, where you should be able to flag a cab.
