Hike Ratings:

The Sierra Club uses the following system to rate the length and elevation gain of hikes. Elevation gain represents the sum of all elevation gains per outing.

Miles Per Day: Elevation Gain Per Day:
1 - up to 6 miles A - less than 1,000 feet
2 - 6 to 10 miles B - 1,000 to 2,000 feet
3 - 10 to 15 miles C - 2,000 to 3,000 feet
4 - 15 to 20 miles D - over 3,000 feet
5 - over 20 miles  

Example: A typical Mt. Tam outing rated 2B indicates the hike will cover 6 to 10 miles, with 1,000 to 2,000 feet of climb.

A minihike is 3 to 4 miles with under 500 feet of climbing.

Backpack ratings include a third digit for travel:

T - Trail

1 - Limited/easy cross-country

2 - Moderate cross-country

3 - Strenuous/difficult cross-country

Cost: GLS does not charge for day outings.

Sign-in Waiver: Must be signed by hikers at the beginning of any hike/event.

Reservations: Reservations for hikes are not needed, except where noted.

Carpools: Riders are expected to share the driver's expenses including bridge tolls, park entrance fees, gas and wear-and-tear. GLS recommends that each rider pay the driver 20 cents per mile plus a share of bridge tolls and other fees. GLS does not guarantee that a driver or rider will be available at a carpool site. Riders should never arrive late; drivers should never leave early.

Riders and drivers arrange carpools themselves. GLS does not take any responsibility for the safety of carpools.

Bad Weather Policy: Continuous rain usually cancels a trip; if in doubt, call the leader.

Dog Policy: Following Sierra Club national policy, dogs are only allowed on hikes that have previously advertised that dogs are welcome in the hike leader description.

Other Trip Information: For more information about any hike (meeting place, time, difficulty) contact the hike leader.
