I'm a local here...=) If one would only visit Tops or Mountain view sometimes taking taxi is not the way to go. (budget wise) One may try private vehicles for hire. The fare in going up and down Nivel Hills would compensate a whole days tour in Cebu and nearby towns using private vehicles for hire. Likewise, you could take the bikes-for-hire-guys ( at the expense of your own risk, but pretty much the route taken by most korean tourist and relatively safe on dry weather) down at the foot of the hill or the jeepneys but i don't recommend unless you have a local accompanying with you. Runners do it on foot at the break of dawn.. Enjoy Cebu!
