Sun, May 30 — Rachel Carson Conservation Park, Brookeville · 3.7 mi

22201 Zion Rd, Brookeville. Large parking lot at the Zion Road entrance. We're doing the Extended Loop — wooded trails along the Hawlings River with dramatic boulder outcroppings, including Rachel's Cairn. About 275 feet of climbing. This is an undeveloped conservation park: no restrooms and no water, so please plan ahead. Long pants and bug spray are recommended, with a tick check afterward. Boots rather than sneakers — the trail is shared with horses and can be muddy.
