A bikepacking adventure through San Diego County, California. Starting from the mountain town of Julian the BFL, Beach, Mountain & Desert Loops showcase the area’s diverse regions, climate and finest riding.



The Julian Bikepack Challenge was originally created as a 3 loop bikepacking route to highlight the incredibly diverse terrain and scenery around San Diego County. The Beach, Desert and Mountain loops are all a mix of pavement, two track and singletrack trails with varying technical levels. Total distance for all three loops is around 450 miles with over 45,000 feet of elevation gain. Total time to do the entire route will be 4-9 days. Each loop has unique character and challenges, and can be done individually.

A single loop option, known as the BFL, combines parts of each of the 3 loops into a big single loop. This loop is close to 300 miles and over 25,000 feet of elevation gain. Should be doable in 3-6 days.


Currently, there are 2 sections of the route which need to be avoided:

  1. The CA Department of Fish and Wildlife (I believe?) shut down a short section of the trail between Pamo Rd and SR78 (around mile 32 on the BFL). This means the entire 4.5 mile section has to be bypassed by continuing south on Pamo Rd, to West Haverdford Rd onto SR78 heading west to rejoin the route. This highway can carry a lot of traffic at times, so be cautious.

  2. There have been reports that the old Banner Toll Road heading up into Julian (around mile 120 on BFL) is overgrown and torn up, for now stick to the asphalt up Banner Grade then use Wynola & Farmer Rd into Julian.

All the loops start and end at the Julian Pie Company in the mountain town of Julian, CA. The address is 2225 Main Street, Julian, CA 92036. A perfect place to reward yourself with the famous Julian Apple Pie and ice cream after completing a loop! Try to park off the main street away from the front of businesses if you are going to leave your car in Julian.

If you are doing the Beach Loop or the BFL, it may be more convenient to start closer to San Diego, for example at Lake Hodges in Escondido.

This is a tough challenge with a lot of miles and elevation gain in remote areas at times. Do not underestimate how difficult it is to ride a fully loaded bike on dirt and gravel roads. Be realistic with how much distance you can cover taking the elevation gain into account when planning your resupply stops and lodging.

We highly recomend getting a Spot Tracker if you are frequent bikepacker. One of the devices can save your life when you get into trouble.

We highly recommend using a GPS device to navigate. For each loop we provide GPX route files on the Downloads page. Some loops can easily be done without a GPS if you have good maps and competent skills. Other loops involve difficult route finding and we note when a GPS is highly recommended. Obviously you can ride all of these routes without one, but following the GPS tracks will in most cases save you the time spent messing around trying to figure out the right way to go.

While the standard Garmin Edge devices will work, you are following a line on the screen and battery life is generally poor. A GPS device with an interactive map works better for bikepacking. Hiking devices like the Garmin eTrex models work very well and as a bonus can be run of AA batteries or a USB battery pack. Cell phone coverage is generally poor/non-existent in the remote areas, so do not rely solely on a cell phone for navigation and emergencies.

There is no specific bike recommendation for the challenge. A hardtail with regular tires will work well for the Beach Loop, a plus or fat bike for the Desert loop and full-suspension bike for the Mountain Loop. Having said that, you can use whatever you have, whether it’s rigid or full-suspension.

The same can be said for tire selection. There are some rocky sections on the loops, therefore tires with tough sidewalls are recommended. The Desert Loop will have a lot of cactus, so a tubeless conversion is HIGHLY recommended. You will be very busy changing flats otherwise!

All loops have some form of services, but except for the coastal part of the Beach Loop, it will not be very frequent - so plan accordingly. We added POIs (points of interest) to each GPS route, including the general location of services.

While there may be natural sources of water on the loops, you will generally have to stock up whenever you get to a service location. If you decide to use a natural source be sure to treat or filter the water accordingly.

Availability of lodging varies with the remoteness of each loop. Generally the closer to civilization you are the more formal lodging can be found and fewer camping options. Dispersed camping is possible on most of the Desert Loop, but on the Mountain Loop you may want to use the campsites available in the State Park.

As the Mountain Loop’s twists and turns can be very confusing in the Mount Laguna area, the GPX is split into three sections to make navigation easier.
