Trip Length

The length of your trip on the TCT will depend on various factors, including your hiking speed, ability, ferry schedule, and campground availability. 

There is no ‘correct’ way to hike the TCT. You can customize your route by piecing together different sections of the trail — taking into account the distances between them — to determine the daily miles that suites you best. 

This allows you to hike your own adventure and tailor the trip to your preferences. 

Sample Suggested Itinerary

4 Days/3 Nights

Day 1: Avalon to Blackjack 10.7miles
Day 2: Blackjack to Little Harbor 9.5miles
Day 3: Little Harbor to Two Harbors 5.5miles
Day 4: Two Harbors to Parson’s Landing 15.2miles 


To make the most of your Trans-Catalina Trail experience, it’s important to consider a few key factors before hitting the trail. Below are some important things to keep in mind.


The weather on Catalina Island can be unpredictable, with strong winds, fog, and sudden rain showers. Check the forecast before you go and be prepared for a range of conditions. Dress in layers and bring rain gear, even if the forecast is clear.

Sun protection is a must. No matter the season, it’s crucial to protect yourself from the sun when hiking on Catalina Island. Even on cooler days with temperatures as low as 60 degrees, the lack of shade can lead to intense heat exposure. To avoid sunburn and other related health risks, it is recommended that hikers wear a hat, apply sunscreen regularly, and consider bringing a lightweight hiking umbrella for added protection.


When hiking on the island, it is important to maintain a safe distance from the wildlife, especially from bison. The Catalina Island Conservancy recommends keeping a minimum distance of 125 feet from bison at all times. While bison generally ignore humans, if they make eye contact or stop what they are doing and pay attention to you, it is a sign of potential annoyance, and you should slowly back away. Bison are tough, confident animals that may react aggressively if they sense danger.

Rattlesnakes are known to inhabit the island throughout the year, with higher sightings between April and October. While encounters with snakes along the TCT are uncommon, it is important to be aware that snakes often seek shelter in the shade of tall grass. It is crucial to understand that young rattlesnakes possess venom and if bitten, immediate medical attention should be sought.


Poison oak is prevalent along the TCT, making it essential to stay on the designated trail and wear protective clothing such as long pants and long-sleeved shirts. In the event of contact with poison oak, it is recommended to promptly wash the affected area with Tecnu or soap and water. Taking these precautions can help minimize the risk of an allergic reaction or skin irritation.

Food Storage / Water

While bears are not present on Catalina Island, critter/fox boxes are provided at most campgrounds to secure your food and personal items. However, it’s important to note that crows can be mischievous at Parson’s Landing and may attempt to access your food by opening bags. Therefore, it is crucial to take necessary precautions to protect your food from crows as well. Safeguarding your provisions from these clever birds will help ensure a trouble-free camping experience.

Water refills can be obtained at the softball field, but the water there may have a metallic taste. It is recommended to bring a water filter to ensure the water’s quality. Potable water is also available at Blackjack campground, Little Harbor campground, and Two Harbors campground. However, it’s worth noting that Parson’s Landing does not have any potable water available. Though water and firewood can be delivered in advance. Additionally, you are required to pick up your locker key (more on this below) from Visitor Services in Two Harbors before heading to Parsons Landing.


There is no cell service in the interior of the island, so it is advisable to hike with a companion if possible, for added safety.

By keeping these factors in mind and preparing accordingly, you can ensure a safe and enjoyable journey on the Trans-Catalina Trail.


Are permits required? Yes, and you must make campground reservations for your full stay.

Conditions on the Trans-Catalina Trail are an important factor to consider when planning your hike. The weather can be unpredictable, and temperatures can vary greatly depending on the time of year and location on the island. The trail is exposed and can be very hot, especially during the summer months. It’s important to bring plenty of water and sun protection, and to be aware of the signs of heat exhaustion and heatstroke.

Additionally, the island can be prone to high winds and sudden changes in weather, particularly on the ridgelines and near the coast. Hikers should be prepared with appropriate clothing and gear for all types of weather conditions.

The availability of water is also a crucial consideration on the Trans-Catalina Trail. There are limited water sources along the trail, and hikers should plan to carry enough water or bring a water filter to treat water from natural sources.

By being aware of and prepared for the various conditions on the trail, hikers can ensure a safer and more enjoyable experience on the Trans-Catalina Trail.

When to Go

The Trans-Catalina Trail is accessible for hiking year-round, but it’s important to be prepared for the weather conditions. Due to its proximity to the Pacific Ocean, gusty winds are common, especially at Parson’s Landing camp and on ridgelines. Additionally, fog can roll in unexpectedly, causing your tent to become soaked without any rainfall. The weather can be unpredictable, but snow is unlikely.

For optimal hiking conditions, it is recommended to hike the TCT in late winter or spring for several reasons. Firstly, the trail is largely exposed, so hiking in the cooler months can be more comfortable. Secondly, during the summer months (July-August), daytime highs can reach the 80’s to 90’s, making for potentially challenging hiking conditions.

Other Special Considerations

On the first day of your journey between Avalon and Blackjack Campground, it’s important to note that there is only one water spigot that should not be missed. After that, you’ll need to be diligent about filling up at every water source you come across, as water is scarce on the trail. Even though there was potable water I did not enjoy the taste, a water filter is helpful. 

However, it’s crucial to be aware that there is no water spigot at Parson’s Landing. Instead, hikers must purchase a locker that contains two gallons of water. Carry enough water to last until you reach the locker. Additionally, make sure to check the availability of the lockers in advance as they may be sold out during peak season.

Overall, water is a precious resource on the trail, and it’s essential to plan ahead and stay hydrated to ensure a safe and enjoyable journey. By being proactive about water management, you can help minimize your impact on the environment and maximize your chances of success on the trail.

Final Thoughts

The Trans-Catalina Trail offers a picturesque experience that is completely doable regardless of your fitness level or hiking experience.

A Few Other Things to Consider


One of the main controversies surrounding the ferry is its policy of not allowing passengers to bring fuel onboard. While this can be frustrating for hikers who rely on fuel for cooking and heating purposes, it’s important to note that safety regulations are in place for a reason.

That being said, it’s worth mentioning that some hikers have reported that they were not asked about carrying fuel onto the ferry, despite the policy. However, it’s important to remember that breaking the rules can have serious consequences, so it’s best to err on the side of caution and comply with the regulations whenever possible.

Ultimately, the decision to carry fuel onto the ferry is a personal one, and hikers should assess the risks and benefits before making a choice. While it may be tempting to take the chance and bring fuel aboard, it’s important to remember that safety should always be a top priority when engaging in outdoor activities.

Safety in the Backcountry

Having wilderness training prior to embarking on a backpacking trip is highly beneficial as it prepares you for potential accidents and unforeseen situations that may arise along the way. Wilderness training equips you with the necessary skills and knowledge to handle emergencies, navigate challenging terrains, and make informed decisions in remote and unfamiliar environments.

As you hike the Trans-Catalina Trail, you’ll not only be immersed in the natural beauty of the island but also have the chance to connect with fellow adventurers and locals. The trail community is filled with warmth and camaraderie, with fellow hikers sharing stories, tips, and a mutual appreciation for the island’s splendor.

Every step along the Trans-Catalina Trail brings you closer to discovering the untamed beauty and raw wilderness of Catalina Island. So lace up your hiking boots, pack your essentials, and embark on this extraordinary journey that promises awe-inspiring vistas, unforgettable encounters, and an experience that will leave you breathless.
