Alkali Hot Springs
Natural hot spring or soaking spot in California. Open for public access.
Sykes Hot Spring is a natural soaking spot located in California. This spot features natural hot spring. Always check current conditions and access rules before visiting.
Trailhead is at Big Sur Station, off CA-1 in Big Sur. Pine Ridge Trail is the standard route. As of recent seasons, day-use permits are required and overnight permits at Sykes Camp itself are limited. Always check the current Los Padres National Forest status before planning.
Spring (March through May) offers blooming wildflowers and reliable creek crossings. Fall (October to early November) has cooler hiking weather. Summer can be hot and exposed; winter rains can flood the trail and make creek crossings dangerous.
Approximately $5 trailhead permit plus $10 parking at Big Sur Station. Reservations may be required during peak seasons; check recreation.gov. No fees at the springs themselves.
Strenuous hike with significant elevation gain (2,000+ feet). Carry plenty of water; on-trail water sources can be unreliable in dry years. The trail traverses areas with poison oak; long pants and long sleeves help. Cell service is essentially nonexistent. Tell someone your itinerary.
Big Sur itself offers Pfeiffer Beach (purple sand), McWay Falls (80-foot waterfall onto a beach), and Bixby Bridge photo stops. The Henry Miller Library is a Big Sur cultural anchor. Carmel-by-the-Sea is 30 minutes north; San Simeon and Hearst Castle are 60 minutes south.
