Preparing by season and route"},"content":{"rendered":"

The short answer: yes, but the leeches are in the forest, not in the villages.<\/strong><\/p>\n

Pu Luong has two faces. Most visitors stay among the rice terraces and villages and hardly ever see a leech. For anyone heading deep into the primary forest, climbing the peak or trail running, it's a different story, especially in the rainy season.<\/p>\n

The irony: the two best seasons for the rice terraces fall right in the peak leech season.<\/strong><\/p>\n

What Pu Luong is like<\/h2>\n

Pu Luong Nature Reserve lies in the northwest of Thanh Hoa province, across Ba Thuoc and Quan Hoa districts, about 170km from Hanoi. Its name means \u201cthe village's highest peak\u201d in the Thai language.<\/p>\n

The reserve covers about 17,662 hectares, roughly three quarters of it primary forest<\/strong>. It is the largest lowland limestone forest in northern Vietnam, with a highest peak of about 1,700m.<\/p>\n

Those three things (primary forest, moisture-holding limestone, mostly low altitude) are exactly the habitat leeches love. Just like Cuc Phuong<\/a>, not far away.<\/p>\n

If you're going to Pu Luong for the golden rice or the flooded fields, the two most popular reasons, prepare for leeches as you would for a real rainy-season forest trip. If comfortable trekking is your priority, local sources all recommend October to April.<\/p>\n

A simple rule: the further you leave the paddies for closed forest canopy, the more leeches.<\/strong> From the villages up to the summit, the fields shrink and give way to dense forest, exactly where leeches gather.<\/p>\n

For trail runners in Pu Luong<\/h2>\n

Pu Luong hosts trail races, with many routes through primary forest. Runners face a higher risk than hikers for three reasons:<\/p>\n
