A Gruta dos Moinhos Velhos (juntamente com a Gruta da Pena e a Gruta da Contenda), faz parte de uma grande rede de galerias com mais de 11 Km de extensão, constituindo dos mais importantes sistemas subterrâneos do Maciço Calcário Estremenho. Caracteriza-se pela existência de dois coletores paragenéticos fósseis, de diâmetro aproximadamente decamétrico, com afluentes desenhando uma rede dendrítica e um conjunto de galerias semi-ativas de traçado dendrítico a norte e angulado a sul. A zona fóssil tem um desnível de 100 metros e a espessura da zona intermédia varia entre 80 metros a montante e 60 metros a jusante, circulando a água por galerias singenéticas, do quadrante norte para o quadrante sul, em direção à exsurgência da Gruta da Pena.

Podem definir-se quatro fases na evolução do sistema. A primeira é representada por galerias freáticas superficiais, de pequeno diâmetro, a segunda pelo coletor paragenético da Galeria Gémea, a terceira pela Galeria Grande e seus afluentes e a última pelas galerias ativas e semi-ativas dos andares inferiores.

"Stop at this review and look elsewhere. Very confusing check in, thats if you can find the reception area. The bungalows are very outdated and worn out. A lot of mildew inside. Terrible sewage smell. "

5/5 Excellent

"A charming boutique hotel. We were welcomed with a glass of port. The location was perfect. It was just a short walk over the river and down into the main shopping and restaurant area. The hotel has a lovely rooftop where you can sit to overlook the city And have a drink."
