From the Seattle Parks Department, "By popular demand, we’re adding a second Bats and Beavers walk this year! Warm summer evenings are the best time to observe bats as they forage back and forth over the wetland ponds, and the resident Beavers as they tend their lodge and dams! Please bring a small flashlight. Start Location: Park in lot #E-1 or #E-2 (off 65th and Lakeshore Drive), and follow the signs to meet at the entry sidewalk right next to the Boat Launch." $3 per person, 2 years and younger free.
