Hike: Hot Springs Mountain (Strenuous) 

Leaders: Sanjiv Nanda and Alan Parks

Join us for this steep 10-mile round-trip hike to the summit of Hot Springs Mountain. At 6535 feet, Hot Springs Mountain is the highest peak in San Diego County, 21 feet higher than Cuyamaca. The total elevation gain/loss is 2200 feet. Most of the hike is on a graded dirt road to an old fire tower. After the tower, an easy uphill trail leads to the peak boulder. Climbing the peak boulder is a nice challenge and a rewarding experience. 360-degree views from the peak looking out to San Gorgonio and San Jacinto to the north, Mt. Palomar and Mt. Cuyamaca to the west and south, and Toro Peak, Anza-Borrego, and Salton Sea to the east. Bring water, snacks, and lunch. Meet at 8 a.m. at the intersection of S2 and Highway 79. No charge. 760-767-3098, or stop by to reserve. Note: The hike and peak are on the Los Coyotes Reservation, and a $10 fee is payable in cash at the entrance station.

Speakers: Tracee Geernaert and Candice Hess, Hawkwatch Leaders
Come to the ABDNHA Library to see and hear what’s new in 2026 for the Swainson’s Hawkwatch. Hear about peak counts, which occur mid-March, and we are hoping for a great year. Our early bloom bodes well for lots of insects, also known as “hawk food.” We will bring photos, anecdotes, and lots of laughs from the field! Register online or call 760-767-3098. GP $12, M $10, V $8.

Leader: Rachel Rench, ABDNHA Volunteer

Join me for an 11-mile RT hike on the Old Wilson Trail from Old Culp Valley Rd to the Overlook, then up to the Wilson Benchmark. This is a fun hike with 800 ft of elevation gain and loss. With lots of rolling hills, it never gets steep anywhere along the way. We'll have a rewarding view at the Overlook and the top of the Wilson Benchmark of Grapevine Canyon and the Salton Sea. The area is at a higher elevation near Ranchita and may have some wildflowers blooming in late March, along with cooler temperatures. High clearance or AWD vehicles will be required, so meet at the ABDNHA parking lot at 7:30 am to arrange carpools. This hike will be limited to 15 people.

Leaders: Carmelita Logerwell and Terri Straub

Hike, 6 miles, 900’ gain. The lucky people who join us on this hike will go through four, yes, four slot canyons!

AWD cars can drive to the start of the hike in South Palm Wash. Regular cars can park at the top and walk 0.2 miles to the start of the hike. No charge. Max 15 people. Meet at ABDNHA by 7:50 a.m. Bring lunch, snacks, and water. Call 760-767-3098 to reserve.

This moderately strenuous 7-mile car-shuttle hike starts on Farmer Road and heads west through a forest of sycamore and oak. After crossing beautiful Santa Ysabel Creek, the trail climbs steeply to the ridge line at around 4000 feet. From there, we begin our descent, cross the San Diego River, and join an old pioneer trail that descends to the Santa Ysabel Preserve Nature Center. The hike is rated moderately strenuous due to steep trails (bring trekking poles if you use them), 600 feet of elevation gain, and 1,600 feet of elevation loss. Meet at 8 a.m. at the Santa Ysabel Preserve Nature Center parking lot. The entrance is on Hwy 79, 0.3 miles north of the intersection with Hwy 78 in Santa Ysabel. From there, we will carpool and shuttle to the start of the hike on Farmer Road. Following the hike, some of us may gather at the Volcan Mountain Winery at the intersection of Farmer Road and Wynola Road. No charge. Call or stop by to reserve: 760-767-3098.
