At half past six in the morning, the boats leave Mirissa harbour in search of blue whales, the largest animals that have ever lived, which pass close to Sri Lanka's southern tip between November and April. Wavelength sits about seven minutes on foot from that harbour, on Sunanda Road, a quiet lane slightly inland from the main coastal road, with Mirissa Beach roughly five minutes away.
The hotel is a small property of around seventeen rooms with air conditioning, minibars, safes and patios, set around a pool with a separate children's pool, hammocks and a garden. A full breakfast buffet is included, bicycles and scooters can be rented, barbecue evenings are organised, and parking and airport transfers are available. Guest ratings range between eight and nearly nine out of ten, with many praising the attentive staff and the breakfast.
