Gosier is really two towns: a cluster of high-rise hotels full of families enjoying the enviable sandy beaches on one side, and a friendly (if rather built-up) Caribbean town next door. There's little interaction between the two, however, and your experience will be strongly colored by which side of town you find yourself in.
Just 8km from Pointe-à-Pitre, Gosier is the biggest tourist spot in Guadeloupe. The hotels are packed close together and share a series of scalloped soft-sand coves, which make it an obvious spot for a family beach holiday.
The town center, about 1km away from hotel central, feels a little run-down and lacks the fine beaches found in the main hotel area, but it is more local in character. It also has a small but attractive beach and a good view across the water to Îlet du Gosier.
