People often describe strange sea creatures by comparing them to familiar land animals, giving the name "cows of the sea" to manatees and "yaks of the sea" to kayaks. Encounter marine mammals with this Groupon.

$25 for a 90-Minute Sea-Cave Tour (Up to $65 Value)

For the sea-cave kayak tour, up to 20 tour-goers paddle in formation behind an experienced guide and cruise through La Jolla's local ecological preserve. Tours launch regularly between 10 a.m. and 4 p.m. daily to explore the seven sea caves from stable, sit-on-top kayaks that are ideal for beginners. The certified guides possess knowledge about the local wildlife and history of the area and mete out anecdotal tidbits that leave tours hungry for more. The groups regularly encounter barking harbor seals and sea lions, curious dolphins, and harmless leopard sharks—proof that a leopard can't change its spots but can exchange its legs for fins.
