did the lighthouse this summer, it was great. We walked there from the port took about 25 minutes then hiked the trail up (note it does have 336 stairs). it was a work out getting up. it was a hot day so definitely do in the morning as there is basically no shade on the trail. We then took a pulmonia (golfcart type taxi), they were at the bottom no problem, to one of the shopping areas and walked around a bit then took another pulmonia back. it seemed the pulmonia's gave better rates in USD than Peso but maybe that was just my conversions, the vendors in shops usually gave a slightly better rate with Pesos.
