万宁游玩指北

离开万宁了，毕竟在这里住了半年之久，好吃的、好喝的、好看的、好玩的还是要记录一下的（￣︶￣）↗ 请注意，该攻略具有时效性 衣 万宁气温要比三亚低一点，但由于五指山脉阻拦了南下的冷气，万宁的冬季也还算温暖。 冬季建议穿 半袖+薄外套 或者是 长袖。 三四月份天气转暖可以穿 半袖，但由于草丛边常见蠓虫，所以仍建议穿 长裤 或做好防虫的准备。 五月份之后白天尤其是下午会很热，但晚上还是凉爽的。晚上散步时可以看到海南人在路边，边喝茶边摆龙门阵。 注意：海南全年紫外线较强，需要涂防晒。四月份之后万宁湿度会很大，要做好阴天时衣服晾不干的准备。 食 大众点评上，神州半岛和石梅湾的饭店评价都偏高，万城镇
