Olompali State Historic Park in United States

Great hike This hike takes about 2 hours at a moderate pace. Narrow trail at times but easy to follow. The history is a plus. Def worth a day hike. Parking was not free. .

Lush in the winter The 3-mi loop is listed as easy on some hiking sites, and it is indeed easy for an experienced hiker.

Great Hike A steady uphill hike of 4 miles takes you to a picnic area overlooking the Petaluma plains. The trail up is well switch-backed and shady, so it works in the hotter days of summer.
