神山位於馬來西亞，神山公園是沙巴的天然遺產，近年被列入『世界遺產』永遠受到維護和保全。
如今冰塊偶爾在高峰下側的水池凝結﹝這小水池是早期登山者祭拜山神的地方，映照峰景，分外瑰麗﹞。

東南亞第一高峰─神山，其花崗岩峰群─南峰、聖約翰峰、驢耳峰、喬治王峰、醜姐妹峰及主峰羅氏峰，矗立雲霄高達4095.2公尺。

攀登神山是一項嚴峻的跋涉，必須具備體力與耐力，如果備足了充沛的體力及二、三天山上行程，便可以觀賞沿著山徑出現的珍禽異獸、岩石、土壤、自然美景以及最古老的奇花異草。
攀登神山，除了享受登山樂趣之外，更因其山峰呈高原之姿，且土質異於國內百岳，故而先了解其形成地質再談攀登感受。

小沙最流連之處：廣闊的灰花崗岩山坡。此山坡的花崗岩乃由多種礦物質組成，各種礦物質對風化和腐蝕的阻力不同，其表面產生了粗糙呈黑、白和灰色的斑點。
如果有多餘時間或體力，小沙真想在這東南亞最高的山峰高原上面翻、滾、躺、坐、臥.冥想…

根據資料，神山的地質始自900萬年前，其花崗岩核心在地殼下面凝固，在100多萬年前這花崗岩群峰便突破地殼，經過侵蝕，沖走千萬尺厚的泥沙、碎石而暴露出來。 在冰河時代，約一萬至十萬年前，高峰由冰雪封住，有一主要冰河向北流下羅氏壑谷。其它小冰河則向東、南、西流下，逐漸磨滑山峰高原，周圍的鋸齒型山峰群則在冰雪表面之上，不受影響。

在一萬年前，冰雪融化了，冰河的跡象可以在山峰高原見到，此處佈滿不及二公分的溝痕，較深的溝痕是冰河內的石塊留下割裂的跡象。冰河時代過後的風化磨平這些痕跡，正如羅氏峰受嚴寒震裂的磐石塊和花崗岩上各類石堆和石堤，有些石層脫落成石板，這是日晒膨脹、夜間嚴寒收縮所致。

如今冰塊偶爾在高峰下側的水池凝結﹝這小水池是早期登山者祭拜山神的地方，映照峰景，分外瑰麗﹞。
山峰高原景色萬分壯麗，尤其令人生畏且崢嶸的羅氏壑谷的懸崖，直瀉深至1250公尺，其形成之裂口，把神山山巒分開為東、西兩個主脈。小沙奮登其峰頂，360度展望，不襟熱淚盈眶…
