We Offer You the Best Things to Do on Saipan

When I started Marianas Trekking 19 years ago, the idea was simple: Create adventures worthy of your very best friend. It’s what drives us every day.

We’ve grown quite a bit over the years, and I think it’s because of our commitment to make sure each adventure is unforgettable and because we really love what we do. We believe in small groups, strong guides, great equipment, and memorable photography.

Vacation days are like gold, and most people don’t get enough of them. If you give us one of those days, we do all we can to make sure it’s the best part of your vacation.

Island Adventure!

"Strongly recommend Marianas Trekking. Great guides for both days. The bikes are assisted which makes it easier to ride up the hills. Great history sites and beautiful ride. The hiking was great, snorkeling, and even went to the secret cave. The staff is great! Great communication. We really enjoyed our time with them."

Forbidden Island + Spa

"The hike to forbidden Island is great if you are in reasonable shape. It's 1km there and 1km back with 160m of ascent/decent. The trail is steep and slippy in places. Also there is a bit of scrambling over the rocks to get down to the rock pool. Well worth it. Kuma did good job looking after us and giving us a laugh..."

Great tour

"Did the "best day of saipan" tour. The bike ride was awesome. Gorgeous scenic views. Great staff especially Johnny who took creative pictures along the way. Saw an octopus while snorkeling. The ATVs were great fun as well. Everything worth the price for a full day of fun."

In Grotto they take a photo (include underwater). After snorkeling we went to spa (many pools, sauna, massage). We spent very pleasure afternoon."
