The water in the vast Amazon River system is largely run-off from the Andes Mountains, and some of the most spectacular scenery and interesting wildlife can be found in the region of Northern Peru where these two gigantic geographical features meet - an area known in Spanish as ceja de selva (literally 'jungle's eye-brow') and incorporating a wide range of eco-systems between the altitudes of 500 m (1,640 ft) and 3,000 m (9,840 ft) above sea level. 

Even at a slightly higher elevation, the heat can be stifling, and so a nice swimming pool is extremely welcome for the purpose of cooling down and calmly taking in one's surroundings. We therefore list below some of our favourites in the high Amazon provinces of San Martin and Amazonas.
