因(yin)主(zhu)峰(feng)(feng)二巨(ju)石并舉，遠望狀(zhuang)如馬(ma)耳，故(gu)名。山(shan)(shan)(shan)勢(shi)為(wei)(wei)東西走向，由片麻巖(yan)、花崗巖(yan)構成。五老峰(feng)(feng)、松朵(duo)峰(feng)(feng)、鴿(ge)崖峰(feng)(feng)等奇(qi)峰(feng)(feng)高(gao)峙競秀，山(shan)(shan)(shan)間嵐氣靄(ai)靄(ai)，泉水淙淙。山(shan)(shan)(shan)坡林木覆(fu)蓋，荊(jing)榛遍(bian)生。山(shan)(shan)(shan)石嶙峋，山(shan)(shan)(shan)勢(shi)陡峭(qiao)，但(dan)有(you)曲徑通幽。這兒有(you)仙人(ren)(ren)洞、龍王(wang)泉、隱龍寺(si)、石龍寺(si)、齊(qi)長(chang)城(cheng)(cheng)和(he)橋上(shang)莊等勝跡。據唐代文學蕭穎士(shi)《馬(ma)耳山(shan)(shan)(shan)記》記載(zai)，仙人(ren)(ren)洞為(wei)(wei)東晉(jin)人(ren)(ren)葛(ge)洪(hong)曾隱居煉丹(dan)之(zhi)地。隱龍寺(si)、石龍寺(si)為(wei)(wei)北魏正(zheng)光時所(suo)建，至清末仍完好，今(jin)已廢圯，公存(cun)遺址(zhi)。山(shan)(shan)(shan)脊處有(you)橫亙綿延(yan)的(de)齊(qi)長(chang)城(cheng)(cheng)。據酈道(dao)元《水經注》記載(zai)：“山(shan)(shan)(shan)上(shang)有(you)長(chang)城(cheng)(cheng)，西接岱山(shan)(shan)(shan)，東連瑯琊(ya)巨(ju)海(hai)，千里余(yu)里，蓋田氏所(suo)造也。”《竹書紀(ji)年》記載(zai)：“齊(qi)長(chang)城(cheng)(cheng)”為(wei)(wei)周顯王(wang)十八年（公元前351年）筑建，至今(jin)已有(you)2349年的(de)歷史。今(jin)有(you)些地段，殘(can)址(zhi)凸出地面1米左右(you)，寬10米左右(you)，基礎多以(yi)(yi)塊石壘(lei)砌。其(qi)上(shang)以(yi)(yi)沙土夯(hang)筑。每遇溝(gou)壑以(yi)(yi)巨(ju)石填筑。曲折蜿蜒，高(gao)低綿亙，十分壯觀。“齊(qi)長(chang)城(cheng)(cheng)”經歷的(de)諸城(cheng)(cheng)段，西自郝戈(ge)莊的(de)馬(ma)耳山(shan)(shan)(shan)，東延(yan)至皇華(hua)鎮(zhen)的(de)龍灣頭，再延(yan)至石門鄉(xiang)的(de)馬(ma)山(shan)(shan)(shan)后，桃園鄉(xiang)的(de)臺家(jia)溝(gou)南嶺，然后入膠(jiao)南市境，全長(chang)30多公里。打開乾隆《諸城(cheng)(cheng)縣志(zhi)·總(zong)圖》可見，馬(ma)耳山(shan)(shan)(shan)與(yu)喜鵲嶺之(zhi)間為(wei)(wei)“黃草關”。這是“齊(qi)長(chang)城(cheng)(cheng)”一道(dao)險峻的(de)關隘。
馬耳山(shan)位于諸(zhu)城城南50里(li)與五蓮縣交界(jie)處，海(hai)拔706.6米(mi)，占地40平方公里(li)，為(wei)魯東南第一高(gao)山(shan)，因主峰雙(shuang)石(shi)并(bing)舉、狀如馬耳得名(ming)，自古為(wei)山(shan)東名(ming)山(shan)。據清乾(qian)隆《諸(zhu)城縣志·山(shan)川(chuan)考》載：“縣境山(shan)以(yi)(yi)百計(ji)，而馬耳居岡脈(mo)之脊，南北諸(zhu)山(shan)脈(mo)絡之不(bu)屬焉者無幾也，以(yi)(yi)是標準之可晰(xi)矣。水以(yi)(yi)數十計(ji)，自馬耳山(shan)以(yi)(yi)南皆(jie)(jie)南流(liu)以(yi)(yi)達于海(hai)，馬耳以(yi)(yi)北皆(jie)(jie)北流(liu)入濰，以(yi)(yi)是界(jie)劃(hua)之可晰(xi)矣。”
馬耳山(shan)(shan)(shan)(shan)(shan)(shan)屬泰(tai)沂山(shan)(shan)(shan)(shan)(shan)(shan)脈，南靠五蓮山(shan)(shan)(shan)(shan)(shan)(shan)、九仙(xian)山(shan)(shan)(shan)(shan)(shan)(shan)、北與常山(shan)(shan)(shan)(shan)(shan)(shan)遙(yao)相(xiang)互，它們(men)同出一(yi)脈，相(xiang)接相(xiang)連，相(xiang)得益彰。山(shan)(shan)(shan)(shan)(shan)(shan)中奇石(shi)(shi)(shi)突兀，峭壁嶙峋，山(shan)(shan)(shan)(shan)(shan)(shan)勢(shi)陡峭而險峻(jun)，自古為(wei)諸城南境之屏障。聳于馬耳山(shan)(shan)(shan)(shan)(shan)(shan)巔者為(wei)馬耳峰(feng)(feng)，西有五老峰(feng)(feng)、大(da)米(mi)山(shan)(shan)(shan)(shan)(shan)(shan)、小米(mi)山(shan)(shan)(shan)(shan)(shan)(shan)、佛頂山(shan)(shan)(shan)(shan)(shan)(shan)、大(da)珠(zhu)山(shan)(shan)(shan)(shan)(shan)(shan)、小珠(zhu)山(shan)(shan)(shan)(shan)(shan)(shan)，東有松朵峰(feng)(feng)、鵓鴿崖，其南還有羊鼻(bi)峰(feng)(feng)、馬鞍口(kou)（即風磨口(kou)）、石(shi)(shi)(shi)人(ren)山(shan)(shan)(shan)(shan)(shan)(shan)、黃朵山(shan)(shan)(shan)(shan)(shan)(shan)、黑(hei)峰(feng)(feng)尖等(deng)。山(shan)(shan)(shan)(shan)(shan)(shan)北麓有永隆寺（俗稱影龍(long)(long)寺、隱龍(long)(long)寺）、石(shi)(shi)(shi)龍(long)(long)寺等(deng)古剎。山(shan)(shan)(shan)(shan)(shan)(shan)中還有一(yi)線天(tian)、鬼見(jian)愁、試(shi)劍石(shi)(shi)(shi)、鱷魚石(shi)(shi)(shi)、鷹(ying)居(ju)崖、菩薩(sa)頂、望海樓、滴水洞(dong)、凌云峰(feng)(feng)、黑(hei)龍(long)(long)潭(tan)、情人(ren)松、天(tian)外來客、太公(gong)祠、太公(gong)坊、太公(gong)亭等(deng)諸多景點。2004年(nian)被(bei)確定(ding)為(wei)省級森林公(gong)園(yuan)。
