The Forest Research Institute of Malaysia, usually shortened to FRIM, protects a large tract of managed rainforest northwest of central Kuala Lumpur. Trails, tall trees, and research plots make it a strong contrast to the city, and guided walks can help explain the forest ecology.
It is best treated as a half-day nature excursion. The site is especially worthwhile for travellers who want rainforest atmosphere without arranging a longer trip into the Malaysian interior.
