What we're about

Welcome to Spirit of Adventure. We are a group of outdoor enthusiasts in Northern California and the San Francisco Bay Area who enjoy things like rock climbing, cave exploring, hiking, backpacking, whitewater rafting and kayaking, ice climbing, mountaineering, skiing and hang gliding/paragliding. If it's in the outdoors and adventurous, we enjoy it. We enjoy frequent trips, great friendships and lots of laughter. We welcome everyone from beginners to the experienced. Our trips are generally planned to introduce people to the outdoors as well as giving experienced adventurists a place to gather. If our trips do not specify that they are for experienced people, everyone is invited. If you are a beginner, you are welcome to participate. Furthermore, we welcome new leaders and people whose experience allows them to teach their skills to others.

Note that we are not professionals or guides so everyone must be personally responsible for their safety and well-being. Yet it is our goal to combine knowledge of the activity, proper equipment and enough planning to make safety our highest goal. Nevertheless, accidents can happen. Personal responsibility is mandatory. By participating in our events, you agree not hold the leaders or members responsible for your safety. You don't have to be in great physical shape to participate. However, you should not have any health issues that would prevent you from enjoying physical exertion. As you enjoy various adventures with us, you will enjoy the feeling of getting in shape.

Please sign up with your full name. Our sign up process is partly a legal release form.

Among our goals is to enjoy a group where we can have good adventures friends. We operate on consensus and democratically, rather than around a single leader. We value positive communications among members and avoid gossip. We welcome your participation and your outdoor gifts.

Campsite at Hodgdon Meadows Yosemite (Climbing, hiking or ?)

Needs a location


We have reserved a campsite at Hodgdon Meadows Campground in Yosemite National Park for these days with an arrival Saturday afternoon to Sunday afternoon. The campsite would be an excellent base for rock climbing, hiking or just enjoying Yosemite.

It would be possible to enter Yosemite in the morning, rock climb or hike on Saturday, camp that night and continue to enjoy an activity on Sunday.

Description for Yosemite camping:
Campsites include picnic table, fire ring, bear locker, nearby flush bathrooms, tap water (at bathrooms), a store in the valley, and no cell signal for most carriers (and no cellular data service).
Camping cost per person is $20 for two nights or $15 for one night of camping, payable to Xiao-Yen. I'll give you a copy of the reservation and the reservation holder's ID, which you will need to enter the park.
Each vehicle entering the park must buy or show a parks pass at the gate ($35 for 3 days, $70 for Yosemite annual, or $80/year for all US National Parks).
Bring climbing gear and proper camping stuff. Rain is unlikely but not impossible. Headlamps, firewood, stove/Jetboil, cooler (not the ginormous ones--need to share the bear box), camp chairs, and hand sanitizer are nice to have. All food, snacks, gum, energy drinks, toothpaste, perfume, and energy bars must be in the car with windows closed and bear lockers during the day and in bear lockers at night. (No food in tents at any time, no food in cars overnight.)
Please do not attend if you have any recent cold/flu symptoms, feel unwell, or tested positive for COVID-19 fewer than 5 days prior to the trip.

Rock Climbing (Top Rope) Sunset Boulder

Needs a location

Come join us for a afternoon of top rope climbing at Sunset Boulder. Bring your rock shoes, harness, and belay device along with something to eat and drink. We plan to have a bunch of ropes set up. Meet us in the parking lot at 1 pm or later at the rock. It's helpful to meet at the parking lot to help us carry ropes to the rock. The parking lot is found at[masked], [masked]

Rafting South Fork of the American

Needs a location


Come join us for a whitewater rafting adventure on the South Fork of the American River. We will be paddling all or part of the river between Chili Bar and Salmon Falls Bridge. This section of the river offers many exciting rapids up to Class IV. For physically fit people, this trip is within the limits of what most beginners can enjoy.

Paddles and life jackets (preferably called PFD's or personal floatation devices) will be provided. We have helmets to loan to most people. We have a limited supply of wet suits available, but for this weekend, it's highly doubtful you will need a wet suit. We will be using everyone's vehicle to accomplish the shuttle. Sometimes it takes up to two hours to finish the shuttle.

The only things you should bring into the raft is a water bottle, sunscreen and a good attitude. Do not bring your keys or food or any other thing that needs a dry bag. If the raft should flip, a dry bag is an entrapment hazard. No alcohol is allowed on the trip until after the rafting is finished.

There will be a $35 fee for this event. You do not have a reserved spot on the trip until you have paid your fees. The fee covers your lunch. We will have a large spread of food of all types. We will provide food for meat eaters and vegetarians. (Lunch meat, sandwich fixings, great quantities of fruit, salads, water, other drinks) About half of the fee goes to paying for everyone's car at the take out, the lunch spot and you admission to the put in area. Those who sign up for the trip will be given the information on how to pay the fee.

Upper Pine Campsite, Yosemite Valley (Rock climb, hike or camp) Weekdays

Needs a location


We have reserved a campsite at Upper Pines in Yosemite Valley for these days with an arrival Tuesday afternoon to Thursday afternoon. The campsite would be an excellent base for rock climbing, hiking or just enjoying Yosemite. Upper Pines is a very nice and sought after campground.

Attendees will be given information on how to obtain the permit for going into the park. This is a new rule for visiting Yosemite this year.
