The graph is deceiving, it's not too tough and feels mainly flat with some little ups and downs toward the end.

What to Expect on the Hike

Turn by Turn Directions

 San Juan Meadow Group Area
The hike starts at the end of San Juan Meadow Group Area. When you pull into the group area, keep driving until the end of the lot where the trail starts.
 San Juan Meadow Group Area map
When you pick up a map at the entrance, it has a zoomed section for the park entrance. This is where the San Juan Meadow Group Area is.
 San Juan Meadow Group Area bathrooms
The San Juan Meadow Group Area has bathrooms and water fountains to fill your hydration pack. Bring more water than you need, it can get very hot here.
Juaneno Trail start
The Juaneno Trail start is well marked. Read any notices and start here.
Juaneno Trail
The Juaneno Trail is well defined and easy to follow.
hike on the Juaneno Trail
Hike straight through the first intersection and stay on the Juaneno Trail.
san juan creek
The hike goes along the banks of San Juan Creek. You can imagine what this looks like after it rains for a few days in the Santa Ana mountains.
Juaneno Trail
When the Juaneno Trail goes into the wash, it’s well marked with rocks.
Juaneno Trail marker
When the Juaneno Trail leaves the wash, there’s a trail marker to confirm you’re on the right path.
Juaneno Trail intersection
Continue straight on the Juaneno Trail.

If you’re not sure where you are, the trail makers are all generally accurate on this hike, and can be cross-referenced with the park map.
ridge line at caspers wilderness park
If you opt for the optional extension on the return trip, you hike along the ridge to the left.
views of Cleveland National Forest
The views of Cleveland National Forest come into view as you gently climb up the valley.
San Juan Creek Trail
A little after 3 miles, the Juaneno Trail will dead end into the San Juan Creek Trail. Hike to the left along the San Juan Creek Trail.
park map
Double check your position using the free park map as you hit trail junctions.
San Juan Creek Trail
The San Juan Creek Trail is more like a dirt road. It also follows Route 74, so expect some traffic noise.
Badger Pass trail
Continue straight on the San Juan Creek Trail as the Badger Pass trail intersects to the left.
San Juan Creek trail
Keep straight on the San Juan Creek trail avoiding any trails to the left.
San Juan Creek trail
The trail becomes primitive but easy to follow. Some other blog posts talk about this stretch being impassable, but it was clear for me.
San Juan Creek trail marker
A San Juan Creek trail marker alerts you to a hard left turn. Head up the hill.
San Juan Creek trail
At the top of the hill, another marker points you right, continuing along the San Juan Creek trail.
San Juan Creek trail marker
Here’s a closeup of the San Juan Creek trail marker at the top of the hill.
San Juan Creek trail
The San Juan Creek trail gets narrow and follows above the valley floor.

After the ridge, the trail goes through a lush section by a small stream. The trail is harder to follow here so keep your eyes open.
Hot Springs Trail
Eventually the trail emerges in a clearing. Stay right on the Hot Springs Trail.
Hot Springs Trail marker
Here’s a closeup of the trail marker at the last intersection. It’s set back in brush and easy to miss.
Hot Springs Trail
The Hot Springs Trail turns into a dirt road and climbs a steep little hill.
Hot Springs Trail
Okay, this part is easy to miss. As soon as you descend from the last hill, keep your eyes open for a small trail to the right.
palm trees
There are a few palm trees that mark the hot springs. After the turn go straight towards them.
San Juan Hot Springs
Here you are, the San Juan Hot Springs! They were smaller than I imagined them, but still cool. Walk around and explore.
San Juan Hot Springs
There are four pools, only one of which is supposed to be cool enough to go in. Again, you’re not allowed to go in the water. OC Parks has video cameras monitoring the pools.
San Juan Hot Springs
The water is crystal clear with gas bubbling up. It’s easy to imagine how this water filled pools in the resort below. Keep your eyes open for pipes heading down to the resort area.
San Juan Hot Springs
If you want to explore more, head down the hill on the paths by the pools for more ruins. Respect the areas marked no trespassing.
hot springs trail
After you’re finished exploring the San Juan Hot Springs, simply head back the way you came.

If you want to mix it up, I have two optional extensions below. One continues on to the old San Juan Capistrano Hot Springs rest area, which is pretty unremarkable but has a cool sign that is great for photo ops. The other extension returns up along the ridge line, offering great views, but a bit of climbing. Or just go back the way you came.

San Juan Capistrano Hot Springs Rest Area Extension

Instead of making the left back the way you came on the Hot Springs Trail, make the right and continue down the hill.

intersection of the Sitton Peak trail
You will come to the intersection of the Sitton Peak trail. Stay to the left.

If you want to hike to Sitton Peak, it’s a good one. I have full hike directions for Sitton Peak on the site here.

intersection of the Sitton Peak trail
Here’s a closeup of that last trail marker for Sitton Peak. If you missed the turnoff to the hot springs and see this trail marker, you’ve gone too far.
San Juan Hot Springs rest area
The trail opens up to the old San Juan Springs rest area. There are picnic benches and some old porta-potties.
San Juan Hot Springs rest area sign
The sign is what everyone wants a photo with. Grab your shot and head back the way you came.

Alternate Way Back on Oso Trail

Again, after visiting the hot springs, you can simply retrace your steps and go back the way you came. If you have the energy, I recommend doing this detour that adds about 3 miles and 1,200 feet of climbing onto the hike, but offers some incredible views. Here’s the GPX file for the hike with this extension: capsers-park-san-juan-hot-springs-extra

Here’s the elevation profile with the extension. It’s about 1200 feet of extra climbing but worth it.

Pick these directions up from the end of the Hot Springs hike directions.

Cold Springs Trail
When you get back to the Cold Springs Trail and Hot Springs Trail intersection, make the right onto Cold Springs Trail.

Continue on the Oso Trail as it descends.
Oso Trail
At this big junction, head left. It’s a little confusing here because it’s the only place where the map doesn’t match the markers. The map shows Oso Trail to the right, but the marker shows Bell Canyon.
bench on trail
Take advantage of the shady bench if you need a break.
East Ridge Trail
The trail comes to a junction. Head left up the steep climb (last one!) on the East Ridge Trail.

A quick note. These directions are meant as a guide for the hike, and not a definitive source. Conditions change, and the information here can be different based on time of day, weather, season, etc. There can be small side trails that you might see but I missed. I have made every effort to include all the information you need to complete the hike successfully. I recommend using this guide in conjunction with a map, GPX file, common sense, and call to the ranger station or park office. If you do the hike and notice something has changed, please contact me and I will update the guide.
