大源林场从兴坪古镇东南面去5公里,有总面积为8.6万公顷的大源林场。那里松杉遍山,桃李满园,群鸟欢歌,溪水潺潺,有良好的生态环境,是旅游、度假的极好去处。人们到大源林场,春可看桃花流水,夏可住避暑山庄,秋可观红叶满山、雾海茫茫,冬可品山珍野味、酒醇茶香……避暑山庄建在大源林场深处冲水潭边,可经公路乘车直达。四周高山峻岭、林海茫茫,惟冲水潭处有一面积约3亩的平地,几处砖瓦建筑,便形成了名副其实的“山庄”。冲水潭为山溪冲成的两处深潭,被通往山庄的公路分成上、下两潭,上潭落差约15米,溪水在数快巨石间飞流直下,浪花飞溅,蔚为壮观,是人们摄影留念的好地方。下潭落差约20米,潭水平缓、宽阔,是避暑的人们经常游泳的好去处。在避暑山庄,人们可以品尝到瑶家正宗的油茶,这里还富藏铅、锌、铜、金、银等矿,开矿的坑道也是一个探险猎奇的好地方,或许还能得块金锭?如遇秋雾,那可就会陶醉了……当秋风送人们到冲水潭,人们会被叮叮咚咚的泉水声吸引,如此美好的泉水源出何处?抬头寻时,却是雾海茫茫。这雾,有的好像白色的绸带,依依不舍地环绕着山头;有的恰似硕大的蘑菇、茶花,在向你展示瑶山的丰收;有的丝丝片片、若离若即地浸漫着山包,使人仿佛觉得,那山包便是瑶家迎接远方来客,刚端上餐桌的佳肴……每当秋雨要下之前,那雾便连成一片,如滔滔海浪,从一个山头到另一个山头向你翻滚而来,使你在深山老林之中,也能领略到大海的情趣。当那雾滚到你的脚下,你会觉得自己一下腾上了天空。这里山的英姿,也因雾的功德,显得更为神奇。马槽冲后的骏马山,每当云雾缭绕山腰,它便如天马行空,气势磅礴。献茶坪旁的美女岭;在雾的笼罩下,更显得朦胧神秘、婀娜多姿。当你来到她的身旁,还没有喝到她手中端着的油茶,整个身心早已被那美的意境所陶醉。上、下茶花岭在雾的装点下,仿佛人间仙境。现在已经有刺激地漂流了。 最近准备搞个国家森林公园
