Baja Sea and Land Wildlife Expedition November 2018 [8 days]

Dive or snorkel in world renowed Cabo Pulmo National Park – release baby sea turtles – kayak at El Arco and Lovers Beach in Cabo San Lucas – swim with whale sharks  – swim with the friendly sea lions of Los Islotes and San Rafaelito, snorkel in some diverse rocky reef habitats, hiking around the hilltops of Balandra Bay, a cultural trip to Todos Santos  …. plus the chance of encounters with whales, dolphins, rays, marine birds and other creatures that frequent our region.

Can you even begin to imagine experiencing all of these bucket-list adventures in just one wildlife expedition? This is possible on the Baja Peninsular in Mexico, a 1200 kilometer strip of land that separates the Pacific Ocean from the Gulf of California [AKA the Sea of Cortez] in Mexico.

This 8 day wildlife expedition will run from November 10 -17, 2018.

Cabo Pulmo Diving / Snorkeling 

  • As a result of over 20 years of protection, Cabo Pulmo National Park is abundant with all kinds of marine life and a must-see for any ocean enthusiast visiting the area. It is widely considered one of the most successful community directed marine protected areas globally and a benchmark for sustainable wildlife tourism.


Sea Turtle Conservation 

  • Releasing the newly hatched sea turtle babies into the Pacific Ocean after gently assisting them out of their protected nest is a rewarding experience for all. Futhermore, your participation contributes to the daily running costs of this all important sea turtle conservation initiative located on the Pacific shore roughly 20 minutes north of Cabo San Lucas.

Kayaking in Cabo San Lucas

  •  Half-day kayaking and snorkeling tour to the popular El Arco and Lovers Beach destinations. A moderate paddle past the famous El Arco (The Arch) in Cabo San Lucas followed by a snorkel out to Neptune’s Finger, a biodiverse marine oasis only accessible by sea.


Swim With Whale Sharks 

  • The whale shark, Rhincodon typus, is the largest living fish/shark species and is categorised as “endangered” on the Internation Union for the Conservation of Nature and Wildlife’s [IUCN’s] red list of threatened species. Swimming with these gentle plankton-eating giants is an unforgettable experience and each trip contributes to the conservation of the species through collaborate research, awareness and education.

Sea lions of Los Islotes & San Rafaelito

  • Los Islotes consists of two small islets at the northern end of the Espiritu Santo Archipelago. It is home to the areas largest colony of California sea lions, Zalophus californianus. Here you can snorkel with the friendly, inquisitive juveniles whilst exploring the caves, rocky coral and diverse marine life.


Our wildlife expedition host, Natalie Lynn, will be escorting a group of expedition participants from her hometown of Chicago on November 9, arriving to San Jose Del Cabo on the 10th. If you are travelling from Chicago or close by, you can join Natalie and the group. Alternatively you can self-arrive to San Jose del Cabo International Airport from anywhere in the world where you will be greeted by one of our team and united with the other guests and Expedition Director at our starting venue.

Whale Shark Conservation Internship

Whale Shark Diaries Conservation Internship Programs are available seasonally in La Paz, Baja California Sur and Cancun, Quintana Roo, Mexico

The whale shark, Rhincodon typus, is listed on the International Union for Conservation of Nature’s (IUCN) red list of threatened species as endangered. The need for placing whale sharks into this classification is due to significantly decreasing sightings and landings of the species at some localities – a trend resulting partly from targeted fisheries at a number of sites globally.
Meanwhile, natural encounters with the majestic whale sharks are growing in global popularity due to their massive size, docile nature and the high likelihood of an interaction at certain aggregation sites.
Concerns have been raised about situations where this lucrative and economically important tourism activity has had a negative impact on certain species including whale sharks.
One issue is injuries inflicted on the whale sharks from boat strikes. Injuries can range in severity from small nicks to deep lacerations and amputations caused by boat propellors. Blunt traumas also occur from boat collisions. However, human-caused mortality rates of whale sharks are unknown.

Whale shark tourism needs to be properly managed to protect both the species and the tourism industry, which is important for the local economy.
Whale Shark Diaries contributes to global research, collecting vital data necessary to gaining a better understanding of the whale sharks of the Gulf of California (aka – the Sea of Cortez) and in the Mexican Atlantic / Caribbean.

Whale Shark Diaries is seeking individuals to join our team as conservation interns. You’ll be given a unique opportunity to gain a basic grounding of the work of conservation biologists working for the conservation and protection of whale sharks in the Gulf of California / Sea of Cortez in Mexico.


  • Photo identification

The spots and stripes pattern of a whale shark is unique to each individual much like the fingerprint of a human being. This whale shark ‘fingerprint’ does not change as the animal grows which means we can monitor the movements of individuals between localities, make estimates of abundance, study population dynamics and evaluate site fidelity. The accepted ‘standard fingerprint’ is the area between the fifth gill slit and the first dorsal fin as shown in the photograph. We maintain our own photo identification library and newly discovered whale sharks are also uploaded to the Wildbook for Whale Sharks, a Wild Me project engineered by Jason Holmberg which consists of a global whale shark database and visual library of whale shark encounters. The database is maintained by marine biologists and citizen scientists from across the globe and the information is used for collaborative research to better understand and protect the species.

  • Migratory studies

Little is known about where all of the whale sharks go when they migrate. Connectivity has been demonstrated between localities within the Gulf of California and also at one site on mainland Mexico but we can not account for all of the sharks. This means there are many pieces missing of the migratory pathways of the whale sharks in our region. Could they be residing in deeper water out of our reach during certain months of the year? Or are they simply feeding in surface waters in a place that we have not yet looked due to remoteness of the area(s)?

Whale Shark Diaries has recently began a collaborative project to search for likely unidentified locations that may have the right seasonal conditions to support a feeding aggregation of whale sharks.

  • Injury analysis

It is common knowledge that around 60% of the whale sharks in La Paz bay have visible boat-caused scarring . Often when new, un-scarred sharks are identified in the bay, later encounters show that some are inflicted with boat injuries within weeks or months of their arrival. The injury analysis data, including video footage and photos, give us the opportunity to raise awareness and improve training with local whale shark tour operators. We are looking to back up this study with some behavioural data in the near future (see behavioural studies below).

Please note: The exact projects you will work on will depend on the time and duration of your stay. We work on photo identification and injury analysis throughout the season but other studies may be shorter in duration. We will ensure you get to work on as many projects as possible during the time you are here to give you a good insight into the life and work of a whale shark conservationist.

All in-water activities that interns are involved in around the whale sharks are within the confinements of the codes of conduct concerning tourist interactions with the species.

Internship Opportunities 2018/2019 season

Whale Shark Diaries Internship Program has limited spaces for conservation interns. Our small team size means that each intern will receive a personal level of attention to their skills development throughout the program. We take your training very seriously and hope you will make the most of your time with us and maybe even go on to use your newly-found skills on other conservation projects in the future.

It is possible to join a program for as little as one week but preference will be given to candidates who can commit to a longer term.

Whale Shark Diaries provides a house for the interns close to the city centre and other ammenties. Utility bills are covered (internet, gas, municipal water and electricity). Food is not included in the project participation fee however cooking facilities are provided. A wide choice of good quality fresh food is readily available and relatively inexpensive.

Please note that flights and travel insurance are not included in the participation fee.

Cultural immersion activities
We will arrange a number of fun cultural activities including (but not limited to);

  • Activities and talks in schools, orphanages, community centres and other venues [school talks are not possible in holiday periods or at times of school examinations
  • Beach and mangrove clean up events
  • Mexican cooking classes
  • Various social events
  • Optional additional trips (*some trips may have an additional fee as we use responsible local tour operator partners for these)

Applications are welcome from anyone eligible who has a genuine interest in marine conservation and of course, whale sharks.
