In the North Grove area:

  • 1. North Grove Trail: A gentle 1.7 mile loop takes you through the historic grove of Giant Sequoias discovered in 1852. "Stroller-friendly" when dry. Allow 1-2 hours.
  • 2. Three Senses Trail: This is a short loop of just a few hundred yards, intended as a sensory experience of the forest. Allow 20 minutes.
  • 3. Grove Overlook Trail: Climbs the ridge for views of the upper parts of the BIg Trees. Allow 1-2 hours.
In the South Grove area:
  • 1. South Grove Trail: Travels through the South Grove Natural Preserve, home to about 1,000 Giant Sequoia, and the largest trees in the park. This moderately difficult trail consists of a 3.5 mile loop through the lower part of the grove, with a 3/4 mile-long spur to the Agassiz Tree - the largest in the park - for a total of 5 miles. Allow 2.5 - 4 hours and be sure to bring water and wear sturdy shoes.
  • 2. Bradley Grove Trail: This 2.5 mile round-trip moderate loop trail travels to a grove of young Giant Sequoias that were planted in the 1950's. Nice area for wildflowers in the late spring. Allow 1-2 hours and bring drinking water.
Other Trails:
  • 1. River Canyon Trail: A strenuous hike into and out of the Stanislaus River Canyon. The hike is 8 miles round-trip with an elevation change of over 1,000 feet. On summer afternoons this south-facing slope can be very warm. Be sure you are physically able to do this hike and carry plenty of drinking water. Allow 4-6 hours.
  • 2. Lava Bluffs Trail: This 2.5 mile loop trail will take you through varied environments. This diverse area hosts the park's most colorful spring wildflower displays and excellent birdwatching. Allow 2-3 hours and bring plenty of water.

HISTORY:   Calaveras Big Trees State Park was created to protect and preserve two groves of Giant Sequoias - the world's largest trees. The historic North Grove became a State Park in 1931, with the more remote and pristine South Grove added in 1954. In addition to the groves, visitors can observe a prime example of west-slope, mid-elevation coniferous forest with it's representative flora. The Stanislaus River, Beaver Creek and North Grove Meadow add a great mix of native plant species to the experience.
