Quepos town services the people that want to visit the park (which is practically everyone). 90% of the shopping facilites, bars, restaurants, clubs, the bus terminal, tourist info, fruit and veg market, council offices, post office, etc. are situated in central Quepos.
Quepos town and Manuel Antonio are both at sea level and between them is a huge steep hill. Manuel Antonio Road (the road going between the two) is not paved, the road is in far from perfect condition, and there are several blind hairpin bends. Combine this with the macho attitude and limited driving ability of most local drivers and the inexperience of tourists driving in a foreign country and it makes trying to walk anywhere along this road extremely dangerous indeed. It is recommended that visitors wanting to go to Manuel Antonio take the bus or catch a taxi from wherever they are staying. The buses from Quepos to MA leave every half an hour between 7am and 7pm with 3 or 4 both before and after these times. It costs 105 colones (20 cents) and takes 10 minutes. It costs the same amount wherever you board it.
