Krabi's mountainous physical geography is broken
by highlands and plains on the mainland.The provincial
administration also covers more than 130 islands
in the Andaman Sea. Natural forest cover is chiefly
mangrove and Cassia trees.
Krabi's sandy clay soil conditions are perfect
for a variety of agricultural products, including
rubber trees, palms, mangos, coconuts, and coffee.
Krabi River flows 5 km through the city and
falls into the Andaman at Tambon Pak Nam. There
are other streams as wel : the Khlong Pakasai,
the Khlong Krabi Yai and the Khlong Krabi Noi in
the province's highest range of mountains, the
Khao Phanom Bencha.
