The hike to Terri Peak, which towers over Lake Perris and offers panoramic views, is a hidden gem. It’s located in Lake Perris State Recreation Area, a park noted more for water sports than hiking. The trail to Terri Peak climbs through boulders and offers plenty of gradual sections to catch your breath and take in the views. You can either hike to the top and back, or you can do the full loop for even more views.

Getting to the Terri Peak Trailhead

There are a few ways to hike to Terri Peak, and this guide will show you the loop hike which I find the most beautiful. You’ll do most of the hike between the lake and the mountain, which offers great views going up and down.

There is an entry fee for the park unless you have a California State Parks Pass.

The trailhead is next to the Ya’i Heki’ Regional Indian Museum (pronounced ya-hee eh-key and meaning “home of the wind” in Cahuilla). You can use this trailhead address:
17801 Lake Perris Dr, Perris, CA 92571

The museum is not always open, and when it’s not, you can’t use the parking lot there.

If the parking lot at the museum is closed, you can park nearby at the Fisherman’s Lot.

Terri Peak Alternate Parking
The Fisherman’s Lot is a 10 minute walk on the side of the road to the trailhead.

There are bathrooms at both parking lots.

Gear for the Hike

This entire hike is exposed, so when the sun is out, it can be brutal. Bring sun protection and lots of water (at least 1.5L). I hike this with light hiking gear, but you can certainly get away with fitness clothes.

Take your selfie stick game to the next level. Part of the fun of a hike is taking pictures, and a flexible JOBY smartphone tripod takes it to the next level. You can use it as a selfie stick, as a regular tripod, but more importantly, as a flexible tripod that can attach to tree branches and other objects. It’s not expensive, and it’s something you can use when not hiking too.

Astro Headlamp

Black Diamond Cosmo 300 Headlamp
If something goes wrong and you get lost, sprain your ankle, or get delayed, you might be caught out after dark. And one of the top items that search and rescue departments recommend you carry is a light. Smartphones can work as flashlights, but that drains the battery quickly. It’s better to invest in a reasonably priced and high-quality headlamp like this Black Diamond. It takes AAA batteries, can last 200 hours, and has an emergency strobe. Carry it with you off the trail to use in emergencies as well.

Terri Peak Loop Trail Maps

The first part of the hike is on small trails that, for the most part, are easy to follow. There are small, unmarked use-trails that branch off at points, but I’ve noted most of them in the directions below. After the peak you’ll descend on larger trails that are shared by mountain bikes. The last part of of the loop ends at a road. If you’ve parked at the museum, there’s a 5 minute walk in the dirt along the side of the road. If you parked at the Fisherman’s Lot, you walk on the paved pedestrian path to the start.

How Are You Going to Navigate This Hike?
Here’s what I use. If you are a hardcore hiker and/or hike in extreme conditions, I recommend getting a dedicated GPS like a GPSMAP 66sr or 66i, or a wrist-based GPS with maps like the Garmin Fenix 7 or Epix. If you only hike in fair weather and a touchscreen is fine, or just want a solid tool, I highly recommend downloading the smartphone app, Gaia GPS. It’s a piece of cake to use and very powerful, just make sure your phone is in airplane mode so the battery doesn’t drain. You can also check for wildfires, weather, snow, and choose from dozens of map types with a premium membership (HikingGuy readers get a big discount here). Note that I also carry a paper map with me in case the phone dies or gets smashed.
