Among the attractions are the old picturesque buildings of Lipa and Taal, the San Juan sulphur springs, the Bawan hot springs, and the Rosario fresh water spring. There are also several caves and grottos. The two largest are found in the slopes of Mount Pulan, Suya, and Kamantigue of San Juan. One of the caves has an opening of 40 meters in circumference. Issuing therefrom is an underground river which empties into Lake Taal. Along its course are extensive galleries and chambers lined with fantastically shaped stalactites and stalagmites. At the approach of an eruption of the Taal Volcano nearby, the cave emits a weird sound, audible at great distances. [Taal Volcano] Taal Volcano is the great scenic asset of the province. Almost at the doors of Manila it is easily reached with practically none of the discomfort which a trip to nature's wild spots usually involves. The volcano is commonly known as the "cloud maker" and "the terrible." How long this volcano has been emitting sulphurous smoke is not known; all that is known is that back in the geologic past, volcanic outbursts of enormous magnitude disturbed the regions about it. In the 18th century the volcano erupted several times, and ruined many towns in the neighborhood. The last and perhaps the worst eruption occurred in January, 1911. Then, after a long interval, old Taal, in a paroxysm of volcanic activity, showed that he was still lusty and capable of making a huge disturbance. In addition to the steam which had been coming from the crater more or less continuously, the volcano began throwing out mud. This activity increased, and culminated in a great explosion at about half past 2 on the morning of January 30th. The hot water, mud, and ashes completely devastated about 90 square miles of country; while some mud and fine ashes fell over an area of more than 800 square miles. Many villages were destroyed and the official estimate of the dead was 1,335. The spasm of activity died away until the volcano again assumed its normal state about February 8th. Since then it has been very quiet, though a small mud geyser has started up along the old fault line which extends from Taal to the coast. This is located on the beach at the village of Sinisian.
