Casa Colibri and Casa Mariposa are in the tiny village of Cocles on the Southern Caribbean Coast of Costa Rica. The nearest town that you will find in most guidebooks is Puerto Viejo de Talamanca which is about 2 miles north.
What Lonely Planet has to say about the area - A decidedly Caribbean concoction of perfect beaches, spectacular surfing and laid-back attitude spiced up with the best music, nightlife and restaurant scene on the coast.
Within 10 miles of the houses there are more than 6 incredible beaches, two national parks with hiking trails, world class surfing, snorkeling along a very active coral reef about 25 feet from the water line on Punta Uva beach and in Manzanillo. Sign up for zipline canopy tours, indigenous reserve walks, visit botanical and butterfly gardens, take yoga classes and go kayaking - most of which you can do on your own or with a guide or group. Terra Venturas is a great option for booking the activities above as well as diving, rafting and dolphin excursions. Check out their website - Terraventuras or stop by the office in Puerto Viejo to arrange an adventure.
