It draws hikers through the Mt. Isarog Panicuason Trail, a Trail Class 4 major climb starting from Barangay Panicuason in Camarines Sur. It rises from Barangay Panicuason outside Naga City to a crater rim.
The views stretch over Lagonoy Gulf and the Mayon group. I returned in October 2026 to update every permit step, fee, and trail note here, covering 69 of the 82 Philippine provinces since 2015.
Key Takeaways
- The Panicuason Trail is rated 5/9 to 6/9 difficulty and is classified as Trail Class 4. It is not suitable for beginners or anyone who does not want a long journey before the climb.
- A licensed guide is mandatory. The current rate is ₱1,000 per day; the ₱500 figure on older listings is no longer valid.
- Online registration and a Landbank deposit must be completed before you arrive at the gate. Walk-in registration on the morning of the climb is not accepted.
- Book early: the daily quota is 20 hikers on the Panicuason trail, and dry-season weekends fill fast.

Where Is Mt. Isarog Located?
Mt. Isarog sits inside the Mt. Isarog Natural Park in Camarines Sur. Naga City is the main gateway.
Barangay Panicuason is the standard jump-off for both the summit trail and Malabsay Falls. The mountain rises northeast of Naga’s city centre.
For climbers, two trails matter in practice. The Panicuason Trail is managed by the Naga City LGU. The Patag-Patag Trail is accessed through Consocep in Tigaon and managed separately by the Tigaon LGU.
Naga City’s pension houses, banks, and the ITPO at City Hall are all within a short tricycle ride of each other, as I found on the morning I processed the permits. That compact layout makes the permit logistics manageable even if you arrive the night before.
Mt. Isarog sits in the same region as Bicol’s most visited tourist spots, and a longer Bicol trip pairs naturally with this climb.
Mt. Isarog Difficulty and Trail Class
The Mt. Isarog hike via the Panicuason Trail is a major climb rated 5/9 to 6/9 on the Pinoy Mountaineer scale and classified as Trail Class 4. Of the 69 Philippine provinces I have hiked across since 2015, the Panicuason Trail’s combination of mud, roots, and leeches puts it firmly in the harder half of that difficulty band.
The 1,000-meter gain from the DENR gate to the rim came through roots and mud the whole way; the trail never widens enough to find a clean line. The cumulative effect is harder than the rating suggests on paper.
Limatik (blood leeches) are active whenever the ground is wet, which is most of the year. They are not dangerous, but they are relentless. Leech socks are not optional.
Mud trenches between Camp 1 and Camp 4 can swallow a standard hiking boot on the wrong step. The only sensible footwear options are:
- Aggressive-tread boots
- Deeply lugged trail runners
Pre-dawn cold at the summit push on Day 2 drops the effective temperature well below the ambient reading. Wind chill and fog saturation drive that drop. A mid-layer is essential even if daytime temperatures feel mild.
At the rim at 6:30 AM in October 2026, I could see Lagonoy Gulf to the east, Naga spread below, and the Mayon group clear against the horizon. El Niño conditions that week gave an unusually clear sky at the rim, which is not typical for October.
Skip this climb if you are a beginner hiker or if you do not want a long journey before the trail starts. A few Trail Class 3 or 4 climbs elsewhere first will make the Panicuason Trail a much more rewarding experience. For the full picture of what Trail Class 4 means across major climb mountains in the Philippines, that reference is worth reading before you commit.
Permits, Guides, and Registration for Mt. Isarog
The online registration and Landbank deposit were the biggest logistical changes from what was previously written about this climb:
- You cannot settle the online registration at the gate on the morning of the climb.
- You cannot settle the Landbank deposit at the gate on the morning of the climb.
Complete every step below before you travel.
The 2026 fee structure for the Panicuason Trail:
| Fee | Filipino | Foreign | Paid to |
|---|---|---|---|
| Climbing permit | ₱100/day per person | ₱500/day per person | City Treasurer’s Office or Landbank |
| Park entrance fee | ₱10 per person | ₱50 per person | City Treasurer’s Office or Landbank |
| Guide fee (mandatory) | ₱1,000/day | ₱1,000/day | Directly to guide |
| Porter fee (optional) | ₱1,000/day | ₱1,000/day | Directly to porter |
I paid ₱1,000 per guide day at the gate; the ₱500 figure on older listings is no longer valid.
Registration steps, in order:
- Download, print, and sign the official LGU Waiver and Release Form. Minors need a signed parental consent form. Bring a valid government ID.
- Fill out the online Mt. Isarog Climbing Permit Form at www2.naga.gov.ph. Upload scanned copies of the signed waiver and ID.
- GCash and Maya are not accepted at the payment gateway.
- Email the deposit slip to tourism@naga.gov.ph. The ITPO verifies payment and endorses the application to the City Environment and Natural Resources Office.
- The approved permit and a blank climbing certificate go to your assigned guide, who gives you the certificate only after the trek is complete.
The rules at the trailhead are:
- Guide ratio: 1 guide per 5 hikers. A group of 6 needs 2 guides.
- The daily quota is 20 hikers on the Panicuason trail. Book early, especially for dry-season weekends.
- The only format permitted for any summit attempt is 2 days, 1 night, with an overnight at Camp 4. Summit day hikes are not permitted.
A July 2026 guide harassment incident led the LGU to need mandatory gender sensitivity and ethics training for all accredited guides; current accreditation includes that certification.
The Naga City portal handles Panicuason permits only. For the Patag-Patag trail in Tigaon, contact the Tigaon LGU directly.
The Panicuason Trail: Campsites, Water Sources, and Cell Signal
The Panicuason Trail passes through six numbered campsites. The ascent to Camp 4 takes roughly 6 hours; descent from Camp 4 to the gate takes roughly 3 to 4 hours. Camp 4 is the standard overnight stop before the pre-dawn summit push on Day 2.
Streams run from Camp 1 through Camp 6, so you do not need to carry two days of water from the jump-off. Ask the gate guide about the Camp 6 source during the March-to-May dry period when flow can drop. Cell signal is unreliable above the forest canopy; download your offline maps before leaving Naga.
The six campsites and the trail route were unchanged from the older accounts I had read when I walked it in October 2026.
The December 2024 illegal logging enforcement has made the Mt. Isarog Guardians a regular presence on the trail, particularly in the mid-section. Guardian patrol teams are now a visible part of the Panicuason Trail experience, and that enforcement presence has improved trail monitoring.
Malabsay Falls sits along the lower section and is accessible as a day trip without a summit permit.
The Panicuason Trail runs through dense montane forest from the gate to the rim. The Patag-Patag Trail in Tigaon takes a different ecological character, passing through more open terrain, which is one reason experienced hikers attempt the cross rather than the same trail twice.
When Did Mt. Isarog Last Erupt?
Mt. Isarog is classified as a potentially active stratovolcano with no recorded last eruption in historical documentation since Spanish-era records began. Trail closures on the Panicuason route are caused by typhoons and illegal logging enforcement, not eruption alerts.
The December 2024 illegal logging discoveries brought heightened monitoring by the Mt. Isarog Guardians. Their patrol presence is now a regular part of the trail experience and a net positive for hiker safety.
Mt. Isarog Itinerary: Overnight Summit Plan
The only permitted format for a summit attempt is 2 days, 1 night, with an overnight at Camp 4. There is no day-hike option to the summit under the current LGU framework.

The itinerary above is the standard route. If you are planning this during September, note that the Peñafrancia Festival in Naga City draws enormous crowds and fills pension houses weeks in advance, making climb logistics much harder. Plan your climb for before or after that festival week.
A 3-day, 2-night cross from Panicuason to Patag-Patag is possible for experienced groups. It needs separate coordination with both the Naga City LGU and the Tigaon LGU and is a significantly more demanding undertaking than the standard overnight.
What to Bring to Mt. Isarog
The list below covers what the Panicuason Trail specifically demands.
Shelter and sleep:
- A lower-rated tent will flood at Camp 4 during overnight rain.
- Wind chill and fog saturation push the effective temperature lower than the number suggests.
- A mid-layer (fleece or synthetic down) for the pre-dawn summit push on Day 2.
Rain and terrain:
- Durable, breathable rain shell. Non-negotiable on this trail.
- Dedicated leech socks. Limatik are active on the trail whenever the ground is wet.
- Knee-high gaiters to keep mud and rattan thorns out of your footwear on the middle and upper sections.
- Aggressive-tread hiking boots or deeply lugged trail runners. Standard running shoes are a real hazard on the root-heavy descent.
Water and food:
- Water sources are available from Camp 1 onward, so you do not need to carry a full two-day supply from the gate.
- Trail food for two days: enough for the climb, Camp 4 dinner and breakfast, and the full descent. Resupply is not possible on the trail.
Documents and navigation:
- Printed and signed LGU Waiver and Release Form, valid government ID, and Landbank deposit slip or ITPO receipt.
- Whistle and headlamp with spare batteries for the pre-dawn summit push.
- Offline maps downloaded before leaving Naga, because cell signal above the forest canopy is not reliable.
Leave single-use plastics at the pension house. The park’s quota and Leave No Trace rules mean you carry everything back out.
Best Time to Hike Mt. Isarog
The best time to hike Mt. Isarog is December to April, when Camarines Sur falls under the northeast monsoon (amihan) and gets its driest, most stable weather. The trail is still muddy in this window, but the risk of being pinned at Camp 4 by a tropical storm is low.
May to November is the wet season. The peak typhoon risk falls between July and October.
The trail does not close automatically during the wet season, but the LGU can suspend permits if a typhoon signal is raised over Camarines Sur. My October 2026 visit landed during an El Niño pattern, which gave unusually dry conditions that week, but that is not typical for October.
Avoid the Peñafrancia Festival week in September. Transport and accommodation in Naga fill up weeks in advance and make the climb logistics much harder.
The December-to-April window gives you the best chance of a clear summit view and the lowest chance of a full downpour on descent.
How to Get to Mt. Isarog from Manila
Getting to Mt. Isarog from Manila means reaching Naga City first, then taking local transport to Barangay Panicuason. The bus is the most practical option for most travelers from Metro Manila.
Before looking at fares, note that Cebgo moved all Naga-bound flights from NAIA to Clark International Airport (CRK) effective March 2026. Travelers who were planning to fly from NAIA will need to revise that plan.
Fares below are as of October 18, 2026. These fares follow diesel and gas prices.
| Operator | Terminal | Class | One-Way Fare |
|---|---|---|---|
| DLTB Co. | PITX / Cubao | Regular AC | ₱909–₱912 |
| Bicol Isarog | PITX / Cubao | Regular AC | ₱950 |
| Bicol Isarog | PITX / Cubao | Elite / Lazyboy | ₱1,100–₱1,380 |
| Bicol Isarog | PITX / Cubao | Skybus Premier / Sleeper | ₱1,500–₱1,800 |
Book an overnight departure between 7:00 PM and 9:00 PM so you arrive in Naga early enough to process permits when the ITPO opens at 8:00 AM. The journey takes 9 to 11 hours. Bicol Isarog has its own booking portal at isarogbus.ph.
From Panicuason, a habal-habal (motorcycle taxi) or chartered tricycle covers the steep final stretch to the DENR gate.
For the Patag-Patag trail, from the Naga CBD terminal take:
- A bus toward Lagonoy, or
- A van toward Goa
Get off at Hanawan junction in Ocampo, then charter a habal-habal for the 8-kilometer ascent to Consocep Mountain Resort in Tigaon.
Private vehicles can reach both jump-offs. Parking is available at Panicuason Hot Springs Resort and at Consocep.
After Isarog, Caramoan Island Hopping is two to three hours southeast of Naga and fits naturally into the same Bicol trip. If you want to extend further south, Albay’s top tourist spots are another two to three hours from Naga and give you Mayon Volcano up close.
Frequently Asked Questions About Mt. Isarog
How do you get to Malabsay Falls from Naga?
Take a jeepney from the Naga City CBD to Barangay Panicuason, then ride a habal-habal to the DENR gate. The falls are accessible on a day trip without a summit permit.
Is the guide really mandatory, or can you go without one?
The guide is legally required. Your permit is issued to your assigned guide, who carries the approved documents for the group. There is no legal way to start the trail without one.
How far is Mt. Isarog from Naga City?
The DENR boundary gate sits higher up the barangay road, reachable by habal-habal or tricycle from the Panicuason junction.
Is Mt. Isarog suitable for beginner hikers?
Skip this climb if you are a beginner.
The trail is rated 5/9 to 6/9 on the Pinoy Mountaineer scale. Key things to know:
- The steepest and muddiest sections are on the upper trail
- The mandatory overnight format means you are carrying a full pack
Browse Philippine mountains by difficulty to find trails that match your current level.
What does the park entrance fee cover?
The ₱10 entrance fee (Filipino) covers access to the Mt. Isarog Natural Park boundary, paid alongside the climbing permit. It applies to summiting and to a visit to Malabsay Falls alike.
Can you do the climb on a tight budget if you go solo?
Going solo is the expensive way to do this climb. In a group of four, that cost splits to ₱500 per person.
Are there toilets or shower facilities on the trail?
There are no formal toilet or shower facilities between the gate and Camp 4. Basic facilities exist at the Panicuason Hot Springs Resort near the gate, where most groups clean up after the descent on Day 2. Bring biodegradable soap and follow Leave No Trace practice on the trail itself.
Is Mt. Isarog Worth the Climb?
Mt. Isarog is worth the effort for intermediate and experienced hikers who want:
- A forested major climb with genuine biodiversity
- Crater rim views of Lagonoy Gulf and the Magayon Trio
- A trail that is still relatively uncrowded compared to the queues on Mt. Pulag or Mt. Apo
The logistics burden is real.
Several factors add up to a trip that needs more planning than most Luzon climbs:
- The advance online registration
- The Landbank deposit
- The overnight-only format
- The long bus ride from Manila before you even start
I went back in October 2026 and found:
- The trail in good condition
- The permit process smoother than the steps suggest once you have done them once
- The crater rim views at 6:30 AM on Day 2 worth the 4:00 AM wake-up
Skip this one if you are a first-time hiker or if a long overnight bus followed immediately by a two-day climb is not your idea of a good weekend. If you have done comparable major climbs and want a Bicol mountain with real forest depth and a hot spring waiting at the finish line, this is a good choice.
The post-descent Kinalas (a noodle soup made from meat scraped from the head of a pig or cow, served in thick brown-sauce broth) in Naga City is the right way to end it.
