It is about 750 meters walking. We usually cut through to the beach at the Noga Hotel. Takes us about 10 minutes. One of the things we liked about Casablanca (one of many) was that nice little distance to town. Staying in town can be a bit more boistorous. Getting home from town, jumping in the crystal clear infinity pool is awesome. And peaceful! Casablanca is nestled just over the hill in a smaller community of nicer accomadations. Best of both worlds for us.
Really... not much longer than the video... ( I just realized!) :) And the route has changed slightly... a little shorter. Also, when there, we often walk from Casablanca (same route) then the entire length of the beach to Lolas, and back again. Round trip comes in at 4 kms.
