My stay at Explora was fantastic! The food was excellent, the room was excellent, the staff were excellent and there was a huge variety of guided tours to go on from horse riding, high altitude hiking, cycling and many less strenuous activities. To top it off, the lodge has its own observatory and the night sky is superb for star gazing. The hotel is an easy 5-10 min walk into the centre of San Pedro or you can get them to drop you in. The Atacama is for getting out and about in so I didn't spend much time in the town centre except to visit the excellent museum and the artisan markets. Explora is expensive but after roughing it in other parts of Latin America for 5 weeks, it was a treat that combined activity and luxury in sufficient doses to totally recharge the batteries.
