The historic High Trips, sometimes large expeditions with more than a hundred participants and crew, have given way to smaller and more numerous excursions held across the United States and abroad. These outings form a major part of Sierra Club culture, and in some chapters, constitute the majority of member activity. Other chapters, however, may sponsor very few outdoor or recreational activities, being focused solely on political advocacy. Generally, chapters in California are much more active with regard to outdoor activities.
