Jump the balefire. The bonfire, or need-fire, is one of the oldest Beltane traditions. When lighting the fire, use nine sacred woods from the following list:
oak, apple, hawthorn, birch, elder, ash, blackthorn, grape vine, mountain ash (rowan), holly, willow, cedar, yew, and hemlock.
Ashes from the balefire can be scattered in the fields as a fertility charm. Women wishing to conceive can tie a bag of the ashes around their necks. Traditionally, cattle and other animals were driven between two fires for protection, healing, and purification. Modern pagans can ritually purify tools or other things in the balefire. Jump the dying embers of the fire for summer blessings.
Dance around the maypole.
Gather the first wild herbs of the season.
Go a-Mayin' by going to the woods and fields to gather flowers. Take a picnic.
Wash your face in dew at sunrise on Beltane for beauty in the coming year. (Traditionally the dew from the hawthorn tree, but dew from grass and flowers will do.)
Make daisy chains and fresh flower wreaths and chaplets (head dresses) to wear and to place atop the maypole. Braid flowers in your hair. Make and wear leafy green masks to represent the Green Man who has returned.
Make a wish at the hawthorn tree, a tree associated with faeries. Place strips of cloth symbolizing your wish in the tree (the color should be appropriate to the nature of your wish, i.e. blue for health, pink or red for love, green or gold for prosperity). Take some time to attune to the tree. When you feel you have contacted its spirit, visualize your wish coming true as you hook the cloth on one of the tree's thorns, chanting your wish. When you have finished, leave a gift for the tree.
Make love in the woods. Beltane is the time of year when the Goddess and God consummate their passions. Traditionally it is a time when lovers pledge to live together for a year and a day. At the end of the period, they may part ways if things haven't worked out. If all has gone well, they may make plans for a handfasting at Midsummer.
Commune with the faeries.
Mark the boundaries of your circle with oatmeal, a traditional Beltane grain.
O Mother, O Woman Eternal
who holdest the inmost life of each of Thy daughters
between the hands upon Her Heart
We swear by Peace and Love to stand,
Heart to Heart and Hand to Hand.
Mark, O Spirit, and hear us now,
confirming this, our Sacred Vow.
