Why don't you take a seat and admire the mountain Keilir which you see in the distance? :) When this cache is placed there is even an eruption quite close to Keilir and you can see smoke coming from behind Keilir.
Sitting here you can also watch the people play golf at the golf course and there is an interesting hotel there too, the Viking fisherman village. This is a rather quiet town you are in now, Álftanes. It belongs now to the municipality of Garðabær. The president lives here, you passed his how on the way here! Isolated, white, with a red roof and a church in the same colors at the side of the house.
