Do you want to climb Toro Peak but don't want to trespass? Toro Peak can be climbed legally with a permit. Call 951 659-2700, ex. 102 for more information.
Contact- Vanessa Minott, Tribal Administrator, Santa Rosa Band of Cahuilla Indians.
Or, visit their facebook page and go to the "contact us/messenger" function to start the permit application process.
A one day hiking permit is $40.00, a multiple day permit is $40.00 per day (on reservation land) and there are no overnight stays permitted inside the reservation boundaries.
Also, please note that the issuance of the permit is not mandatory. In other words, your request could be rejected.
This area has been a hot bed of illegal entry in the recent past, and the tribe is sensitive about it. Something to keep in mind when applying for the permit.

Thanks. Maybe post this on the Toro Peak SP page, for posterity?

Yes, I posted it there first under the comments section, and asked the page owner to update the page.

Wasn't Toro Peak formerly on BLM land (Bureau of Land Management, not Black Lives Matter)? and tranfered to a local Indian tribe in the area not too long ago? I'd been up there years ago and remember the only restrictions were no motorized vehicles (there was a gate across the road), no overnight camping, stay on the trail (actually a dirt road), and it could be closed at any time due to the communications facility on its summit (DoD/USMC-related). That's sad the local tribe is now charging $40 for access as that was a nice summit view out over the Coachella Valley and Salton Sea area. Short hike, too, about 3.5 miles each way IIRC. Good 'warm-up' hike for nearby Rabbit Peak.

(re-edit) From Wikipedia-
The Santa Rosa Indian Reservation, not to be confused with the Santa Rosa Rancheria, is a reservation in Riverside County in the Santa Rosa Mountains, near the town of Anza. It is 11,092 acres (44.89 km2) acres large.[1] It was established in 1907.

The HPS website states that the peak was on the original list in 1946, and removed in 1975 when free access was denied. It does not elaborate any further than that. It's very possible that access was still available through a paid permit after 1975 but I've found nothing to either prove or disprove that.
