Koh Samui has a beach for every kind of traveller. Chaweng is best for nightlife and activities, while Lamai offers a more relaxed atmosphere. Silver Beach is a small bay with clear water, and Choeng Mon is great for swimming. For a quieter escape, head to Bophut, Maenam or the west coast. December to April is generally a good time to visit, while October and November bring more rain and rougher sea conditions.

サムイ島のおすすめビーチ7選 - thumbnail

サムイ島のビーチは、にぎやかなチャウエンから北部・西部の静かな湾までさまざまです。チャウエンやラマイなど東海岸のビーチは10月と11月に波が高く大雨になることがあり、夕日を見るなら西海岸です。

1. チャウエンビーチ、コ・サムイ

フォームキャノンとビーチバーのバトル

Nam: The most popular beach on Koh Samui, stretching for around 7 km along the east coast. Expect white sand, plenty of beachfront restaurants, hotels, water activities and lively nightlife. Visit early in the morning for a quieter experience.

チャウエンビーチ、コ・サムイ

注目ポイント

バーのクルーがチャウエンビーチロードを長い水路に変えています。クラブの外にはフォームキャノン、ミニマートのリフィルステーション、ドラムとバケツを持ったピックアップチームが見られます。DJがグリーンマンゴーエリアの近くで音楽を流し、ビーチバーは砂に水しぶきのラインを設定しています。この雰囲気はパーティーとプールのエネルギーが混ざり合っているため、朝は泳ぎ、正午以降はストリートに参加できます。タクシーとバイクタクシーは濡れたゾーンを避けているので、コアストリップを歩き、休憩が必要な時はサイドレーンを利用してください。多くのホテルがアクションの近くにあり、ギアのリセットやシャワーを簡単に行うことができます。大騒ぎせずにしっかりと水に浸かりたいグループにとって、チャウエンは絶妙なスポットです。

Nam: A small, picturesque bay tucked between Chaweng and Lamai. Its soft sand, granite boulders and clear water make it a popular spot for swimming and snorkelling. It can get crowded due to its small size, so arrive early for the best experience.

Nam: A beach with a charming village atmosphere, backed by boutique hotels, restaurants and seaside cafés. Fisherman's Village is especially lively on Friday evenings, when its walking street market brings food stalls and local shopping to the area.

Nam: A long, quiet beach on Koh Samui's west coast and one of the island's best places to watch the sunset. The water stays shallow far from the shore, which suits families with young children, but at low tide the sea pulls back a long way, so check the tide before you swim.
