Upper Marikina River Basin Protected Landscape

The Upper Marikina River Basin Protected Landscape (UMRBPL) spans 29 kms covering five municipalities of Rizal -- Rodriguez, Antipolo, Baras, San Mateo and Tanay. It is also surrounded by significant bodies of water such as the Boso-Boso River, Sapa Bute-Bute, Tayabasan River, Montalban River and the Wawa Dam.

UMRBPL is originally of mountain forest and tropical forest such as Dipterocarp forest-consisting of Tanguile, Mayapis, Nato, White Lauan, Red Lauan, Bagtikan and other important commercial species such as Dungon, Molave (Molawin), Akleng Parang and Balayong. While logging was prevalent before, prior to its designation as a watershed reserve, only 30 percent forest cover remains in the area. The virgin forest however, can still be found in the Montalban area.

The UMRBPL is considered one of the most important protected areas being supervised by the DENR as the watershed is a potential source of water for Metro Manila.

The area is rich in base rocks composed of basalt, tuff, breccia, agglomerate, and tuffaceous clastic rocks. High permeability has characterized the Montalban limestone near the Wawa Valley and Masungi San Andres limestone in the Boso-Boso. Meanwhile, the northern upper reaches are full of volcanic clastic and volcanic products. Boso-Boso River Basin and lower reaches have developed alluvium sediments. Beach along Montalban has sand sediments while Boso-Boso has clayish red soil.

The UMRBPL is home to the Philippine Eagle (Pithecophaga jefferyii), Labuyo (Gallus gallus), Quail (Coturnix sp.), and the Philippine Hawk Eagle (Spizaetus philippensis) as well as deers, wild pigs, Palm Civet cats pythons and monitor lizards.


The area takes pride in its unique cave – the Pamitinan cave, believed to be one of the rendezvous of the Katipuneros of the Katipunan during the Spanish era.

It is also frequented by visitors and other religious sectors during summer months and Holy Week. It is also a picnic area where visitors enjoy the scenic view of Wawa Dam and other unique rock formations, downstream of Wawa Dam.

Caves and green vegetation are also a major draw for mountain climbers/mountain trekkers and others.


UMRBPL is situated about 20 km east of Manila and its paved roads can be accessed by practically all types of land transportation. It has three (3) entry points, two of which are located in Antipolo City via Marcos Highway in Sitio Cabading and in Sitio Kaysakat, both in Brgy. San Jose, and another thru Sitio Wawa in Brgy. San Rafael, Rodriguez.

In general, jeepneys regularly ply the local thoroughfares between the city/municipalities and barangays. However during the rainy season, dirt roads in remote barangays/sitios are not readily accessible. At present, the LGU of Antipolo City is implementing road improvements, specifically in Sitio San Ysiro, Brgy. San Jose.
