Hikers
Attention SIR Hikers! We hike on the second and last Tuesdays of every month on regional trails. The second Tuesday hike is rated Easy, the last Tuesday hike is rated Moderate or higher. Easy hikes are typically 3 – 5 miles long and usually take about 1.5 – 2.0 hours. Moderate or higher hikes are usually 5 – 7 miles long and typically take 2.5 to 3 hours. Hikes start at the trail head at 10:00 am, unless otherwise specified in the hike description below. Water, wide brim hats, hiking shoes and sticks are always recommended. Some of us often but not always have lunch at a nearby restaurant after the hike.
NEW MEMBERS, SPOUSES/PARTNERS, GUESTS, and SIR members from other Branches are always welcome.
