A few notes: Take lots of water. I've been lost on this trail several times and run out of water. No fun. This is a killer fun trail in dry season, but can be super muddy in rainy season depending on the day. There are a few points where you need to hike... Very technical. There are a bunch of really fun trails in this area. Combo of fire roads and cattle trails. Steep, rocky ascents and descents and fun fire roads.

Trail starts across the Panamericana from the Fish Market right near the new Rio Hato Airport. Take the long straight fire road that enters the teak plantation for 1 mile. Trail will veer to the right past a couple buildings, stables and a taller. Stay on the trail for 2 more miles until you reach the power lines.

From here look left for a utility road that follows the power lines (mile 3). Steep gravel road drop for a few hundred feet. Cross a small stream (rideable) and then a good climb of 8-9% grade until about mile when trail descends. Rough and rocky. Few hundred feet drop to a larger stream (around mile 3.5) that's usually rideable. Power up hard on the other side. Very steep and muddy and may need to walk for a bit.

From here, another long steep ascent until about mile 3.7, when trail splits. Take the fire road to the right until just before the 4 mile mark. From here you'll take a right off the fire road to a very cool (and bizarre) cattle trail. You may have to check for the trail in rainy season, but suggest looking at the map in satellite mode to see where it starts. Trail winds through some truly bizarre moonlike terrain that's easy and fun to follow. Eventually you'll come to a cattle fence. Pass through (close the fence) and continue on the trail. Trail will split again, so veer left and continue... If you get lost, backtrack.

At mile 4.7, you'll come to another fire road. Go left, pick a line and bomb down the road until about mile 5. From here, it gets very technical, lots of washout. Rideable, but pick a good line as some of the ruts are pretty deep. Eventually, you'll reach Rio Farrallon, which has a small concrete dam that you can ride across. Pick up some fun singletrack through the trees for a few hundred feet. At this point, you'll need to walk... The trail is brutal and at one point completely unrideable. Eventually, you'll pick up the singletrack again. (If you get lost look for the powerlines as you'll want to end up back that way.)

When you reach the powerlines, take a left. (You can see where I got lost at mile 5.Cool Funnest part of the ride... Long bomber road, another cattle fence (close it!) and then another long fun service road back in the plantation. After a great descent, you'll cross Rio Farrallon again (mile 8.5) rideable in dry season otherwise hike it... And then a long ascent back to the road you came in on.
