Carite State Forest Observatory Ridge Trail
Cloud forest technical climb to abandoned towers.
The old access road to Carite’s communication towers winds through dense cloud forest at 3,000 feet, where morning mist clings to sierra palm and tabonuco trees. You’ll navigate washouts and fallen logs on this forgotten maintenance road that dead-ends at a cluster of abandoned radio equipment with sweeping views toward the Caribbean coast. The real challenge comes at kilometer 4, where Hurricane María’s damage created a boulder field that requires careful line selection.
This is moderate technical terrain demanding high clearance and 4WD low range for the steepest pitches. Mud can be treacherous during the May-October wet season; December through April offers better traction but cooler temperatures mean thick fog can roll in fast. No permits needed, but fuel up in Cayey before heading up — there’s nothing but forest for miles. The payoff is camping among the towers with views few locals ever see.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner handle Observatory Ridge, or do I need a lift?
A stock high-clearance 4WD will get through, but the rocky climb sections and embedded roots will punish low-clearance rigs. Skid plates are a smart call — the rock faces on the upper ridge are unforgiving on exposed oil pans.
What time of year should I avoid this trail?
May through November is hurricane season and the forest gets saturated — trail surfaces turn to slick mud and water crossings run significantly higher. December through April is the dry season window and the go-to for this trail.
Do I need a permit to run Observatory Ridge or camp in Carite State Forest?
Camping requires a permit from the Puerto Rico Department of Natural Resources (DRNA) — contact their Cayey district office ahead of time, walk-ins are not guaranteed. Day use on the trail itself doesn't require a fee, but check current DRNA access status before you go since closures happen post-storm.
What's the hardest section on this trail and what should I be ready for?
The upper ridge push toward the abandoned towers is where it gets real — steep loose rock shelves with limited line choice and tight tree canopy that leaves zero room to correct a bad approach angle. Take it slow, walk it first if you're unsure, and don't count on a recovery anchor being nearby.
Is there any place to fuel up or get water near the trailhead, and does cell service exist on trail?
Fuel up in Cayey before heading in — it's your last reliable stop. There are water crossings on trail but treat anything you collect; no potable water sources exist in the forest. Cell service is dead once you're in the canopy, so download offline maps and file a trip plan with someone before you roll.
