Our Scientists in Parks staff will present findings from bat bioacoustic surveys and species diversity results spanning 2020-2026. Discover how scientists record and analyze bat echolocation calls and what they can tell us. There will be a Q&A session at the end for you to ask all your burning bat questions.

Zuni-Acoma Trail Guided Hike

Offered Sundays: August 2, 9, 16, 23, and 30
10:00 am - 1:00 pm

Location: Zuni-Acoma West Trailhead, 17 miles south of Grants on Highway 53. From exit 81 on Interstate 40, head south on Highway 53, and turn just past mile marker 70. *Please note the Zuni-Acoma Trail has a second trailhead located on Highway 117. Be sure to go to the west (Highway 53) trailhead.

Take a guided hike with a ranger and discover the hidden life, diversity, and resilience thriving on the Twin Craters lava flow. The first part of the hike is through grassland along a dirt trail. Eventually, the trail turns into a cairn-marked route across rubbly lava flows with loose rocks. The guided portion of the hike will cover about the first 1.5 - 2 miles of the trail and return to the parking area along the same route. Bring comfortable hiking boots, weather appropriate clothing, water, snacks, sunscreen, and a hat.
