This study aims to determine: 1) The level of the tilt Samalona Island Beach, and 2) Type of bottom sediment grain for the benefit of coastal tourism in Makassar, South Sulawesi island Samalona. The scope of the research includes the measurement of Coastal Geomorphology parameters (substrate / sediment and slope of the beach). Measurement data in the form of data used for the slope of the beach then Samalona Island shoreline mapping and to determine the point of observation that can be exploited for the benefit of coastal tourism. Bottom sediment samples will be analyzed in the laboratory to determine the type of bottomsediment grains, so we get the value of the sorting that was one deciding factor whether or not safe observation point used as a beach tourist sites. The results showed that the level of Samalona Island beach slope is between 0.02 to 3%, which indicates that the island Samalona can be used as a beach resort with a beach slope levels were nearly flat, except in the southern part of the island at a depth of 17 meters which is only used by people are adept at swimming. For silt and clay (<0.063 mm) very rarely found at any observation point, there was even a 7 number of observation points that are not contained silt and clay, and the type of sediment at each point of observation is a kind of coarse sand. The region around the island waters Samalona have a goodbase material and not easily stirred (stable), seen from the sediment grain sorting in the category of medium to good. This indicates that the deposition process on the system hydrodynamics including calm waters, so it can be said that in terms of the condition of the material making up the bottom waters, in general this area deserves to be a tourist area, especially for the washing of the coast. Results of laboratory analysis showed that the type of sediment / substrate dominated by coarse sand with a grain size of 0.0063 to 2 mm, which is in the Medium category and the category Good Enough, so that the value is allowed for beach tourism activities such as swimming or diving
