On my second day in Barcelona, I had to choose between activating an historic two-point peak, Sant Jeroni (EA3/BC-012) or trying one of the four one-point peaks along the coast to the northeast of Barcelona, EA3/BC-015, 16, 17, and 18.
Sant Jeroni is the site of a monastery and is well-described online. There is a funicular railway that runs some distance towards the peak, and the peak can be reached by stairs from two sides. Early Saturday morning, I decided that I would rather find my way up some local trails than deal with the press of tourists at a popular site.
On the previous day, I had tried to take the rental car up EA3/BC-015, and found that I could not get very far up the mountain road. I was concerned that the same would be true of all of the peaks along the coast, but thought it would be fun to try anyhow.
