The amenities that really stand out for the Crystal Endeavor is its pair of eight-passenger helicopters for excursions and an onboard submarine for underwater exploration.

Crystal offers some of the best shore excursions, including highlights sightseeing tours for first-time visitors to recreational tours that include some gentle exercise. A refreshing part of their excursions is their You Care, We Care voluntourism outings where you can volunteer in the community for no charge. We suggest you make your reservations for shore excursions before the cruise departs as the popular ones will sell out.

From the Endeavor's marina, passengers board tenders to ports of call, swim off a platform attached to the ship's hull and take advantage of recreational options that include snorkelling, water skiing, kayaks and Jet Skis.

There is no theatre, but evening entertainment options are available.

Considering the size and type of ship, Endeavor has plenty of enrichment programmes, including guest lectures, classes and more.

A two-story solarium on the upper decks features a glass-domed pool.

Here, you can relax and recharge in serene treatment rooms, and experience rejuvenating services such as Aroma Stone Therapy, Japanese Silk Booster Facial and Well-Being Massages. The salon offers haircuts, styling and treatments using Kerastase products; manicures and pedicures; waxing; teeth whitening; men's barbering services; and lash enhancing.

The fitness centre offers state of the art Technogym machines as well as a range of free weights. The centre also offers complimentary yoga, Chi-energizing, mat Pilates and stretch classes, as well as Tour de Spin indoor cycling, circuit training, and aerobics.

In the evening, you'll find live music and dancing.

The Endeavor even has an onboard casino, which is pretty special as it's the only one available on an expedition yacht.

Crystal Endeavor's family-friendly program details have not yet been released.
