Masachapa's beach is a long sweep of dark volcanic sand facing the open Pacific. The colour of the sand is striking — almost black in wet patches, dark grey when dry — a result of the volcanic geology that runs the length of Nicaragua's Pacific coast. The water is warm but the surf is real: there is consistent swell here, and the currents can be strong. It is a reasonable beginner surf spot when conditions are moderate, but not a safe swimming beach for children or non-swimmers without care.
On weekdays the beach is quiet enough that you can walk a long stretch without meeting many people. Fishing boats are launched from the northern end of the village early in the morning, and it is worth being up to watch them come in. On weekends, Managuan families fill the comedores and the sand fills up, which adds energy but removes the solitude.
Swim where you can see others swimming. There are no lifeguards.
